Red, white and maybe feeling blue?

BEIJING — Coming into these 2015 track and field world championships, it looked for — and to —  all the world like this could be the meet when the American team finally reached that elusive 30-total medal count.

With the meet now at its (just-past) halfway point, that looks exceedingly unlikely. The question now is more fundamental: is this 2015 performance a blip or a precursor for next year’s Rio 2016 Summer Games and, indeed, beyond?

Coming into Wednesday, four nights into the nine-day meet, the United States had exactly as many golds as Canada: one.

The American Joe Kovacs won the men’s shot put; the Canadian Shawn Barber, the men’s pole vault.

After Wednesday, the United States still had -- one. 

The Brits? Three. The Americans' new political friends in Cuba? Two.

Overall, Kenya led the medal count, with 11, six gold; the Americans were next, with nine (that one gold, three silver, five bronze).

Kenya is not just marathoners anymore. Julius Yego won the men's javelin Wednesday night with the farthest throw in 14 years, 92.72 meters, or 304 feet, 2 inches.

Meanwhile, the IAAF announced earlier in the evening that two Kenyans, Francisca Koki and Joyce Zakari, had tested positive after providing samples on August 20 and 21, respectively — that is, immediately before the meet started. These “targeted tests were conducted by the IAAF at the athlete hotels,” the federation said in a statement. No other details were immediately available.

The run-up to the 2015 championships has been marked by waves of media reports alleging doping positives and cover-ups in the Kenyan track and field scene.

Zakari had run second in her 400 heat in 50.71, then proved a no-show for the first of Tuesday’s three semifinals.

Koki, in the 400 hurdles, ran 58.96 in her opening round, second-slowest in the entire field.

For the U.S. to prevail in the medals count next year at Rio, as it did in London 2012, with 103, China next at 88, the weight rests on its track and swim teams.

In London, the swim team won 30 medals at the pool, 31 including Haley Anderson’s silver in the open-water competition. The track team: 29.

A few weeks ago at the 2015 world swim championships in Kazan, Russia, the U.S. team ended up with 23 medals, eight gold. That’s arguably misleading, though, because two of those medals came in the mixed relays, which would be new Olympic events. So: 21.

Of course, Michael Phelps did not swim in Kazan and threw down three world-best performances that same week at the U.S. nationals. Even so, it was arguably the American team’s poorest performance at a worlds dating to 1973; in 1994, the Americans went home from Rome with 21 medals, four gold.

For the track team, expectations had soared before this meet in Beijing, the U.S. sending arguably its deepest team ever.

To be sure, the Americans have had some successes. In the women’s 10,000 meters, for example, U.S. runners went 3-4-6, Emily Infeld passing Molly Huddle at the line for the bronze, Shalane Flanagan taking sixth.

Shamier Little, with a bright green bow in her hair, and Cassandra Tate went 2-3 Wednesday night in the women's 400 hurdles. Zuzana Hejnova of the Czech Republic, the Moscow 2013 champion who had spent most of 2014 recovering from a broken bone in her left foot, dominated again in a 2015 world best 53.50. Little ran 53.94, Tate 54.02.

The final events Wednesday night, however, proved hugely emblematic of American performance:

Only one American, Justin Gatlin, had even made it through the heats to the semifinals of the men’s 200. He ran an easy 19.87 to move on to the finals, that 19.87 the second-fastest semifinal time ever at a worlds; Francis Obikwelu ran 19.84 in 1999.

Justin Gatlin's 19.87 in the men's 200m semi tonight was the second-fastest semifinal time ever at the World Championships. The fastest: Nigeria's Francis Obikwelu's 19.84, in 1999.

In the next heat, Usain Bolt, who defeated Gatlin in the 100 Sunday night by one-hundredth of a second, ran a season-best 19.95, chatting with South Africa's Anaso Jobodwana in the next lane, second in 20.01, as they crossed the line. 

In the women's pole vault, American Jenn Suhr, the 2012 Olympic champion, afforded a huge opportunity because Russia's Yelena Isinbayeva was not jumping (the all-time pole vault diva gave birth last June to a daughter), managed a tie for fourth, at 4.70 meters, or 15 feet, 5 inches -- along with another American, Sandi Morris, a rising college star, and Sweden's Angelica Bengtsson.

Cuba's Yarisley Silva won, with 4.90, or 16-0 3/4. Brazil's Fabiana Murer took second, at 4.85, 15-11. Greece's Nikoleta Kyriakopoulo got third, at 4.80, 15-9.

Silva made three attempts at 5.01, 16-5, but did not clear. Isinbayeva holds the world record, 5.06, 16-7, set six years ago.

Emma Coburn had been a medal hope in the women's 3000 steeplechase. She finished fifth, in 9:21.78. Hyvin Kiyeng Jepkemoi of -- where else? -- Kenya took gold, in 9:19.11. Habiba Shribi of Tunisia came second, 13-hundredths back, Gesa Felicitas Krause of Germany in a personal-best 9:19.25, 14-hundredths behind.

The men's 400 proved super-crazy fast.

The American LaShawn Merritt, the Moscow 2013 and Beijing 2008 Olympic champion, in Lane 8, went out hard early on the way to personal-best 43.65. He got second.

South Africa's Wayde Van Niekerk ran 43.48, unequivocally the fastest time of 2015. Kirani James of Grenada got third, in a season-best 43.78, Luguelin Santos of the Dominican Republic fourth in a national-record 44.11.

Van Niekerk's best before Wednesday had been more than a half-second slower, 43.96. His 43.48 makes him the fourth-fastest man ever at the distance: Michael Johnson (43.18), Butch Reynolds, Jeremy Wariner.

The second-, third- and fourth-place finishes? The fastest times for those positions ever at a worlds.

Van Niekerk was taken off the track in a stretcher. His condition was not immediately available.

Merritt's silver tied him with Carl Lewis as the most successful American man in worlds history, with 10 medals. He has five 4x400 relay medals (all gold, dating to 2005) and five in the open 400 (two gold, three silver).

Watch out going forward, meantime, for Isaac Makwala of Botswana, fifth in 44.63.

Makwala had shown up big-time in the semifinals, with the field’s top time, 44.11, and from the outside lane. With an electric-green sleeve on his right arm, he dropped after the finish line and gave the crowd five push-ups, a signal that the semis amounted to nothing more than a training run.

For literally decades, the 400 has been an American stronghold, dominated by the likes of Johnson, Reynolds, Wariner and Merritt. Indeed, aside from 2011 and 2001, an American athlete had won the 400 at every worlds dating to 1991.

Merritt took second in 2011 when James announced his arrival on the world stage; Merritt was coming back that year from a doping ban, and he and James have since traded off titles, James winning in London in 2012, Merritt in Moscow in 2013.

Any discussion of what this all means, if anything, must start with the acknowledgement that the rest of the world has gotten way better at events that Americans used to regularly be able to count on for production in the medals count.

To take another beyond the men’s 400, consider the men’s 400 hurdles:

Helsinki 2005, for instance: two medals, gold and silver. Osaka 2007: one, gold. Berlin 2009, one, gold.

Daegu 2011: zero, with Britain, Puerto Rico and South Africa 1-2-3, the best Americans sixth and seventh.

Moscow 2013: one, a silver, Jehue Gordon of Trinidad & Tobago winning, Emir Bekric of Serbia taking third.

Beijing 2015: Kenya-Russia-Bahamas went 1-2-3.

The Americans finished fourth (Kerron Clement, the 2007 and 2009 world champion who had spent 2014 battling injuries) and eighth (Michael Tinsley, the 2012 Olympic and 2013 worlds silver medalist, in 50.02, after crashing through the eighth hurdle).

Two Americans had put down the year’s best time before this meet, Bershawn Jackson, 48.09, and Johnny Dutch, 48.13. Neither made it to the final.

For emphasis: Kenya had won 45 gold medals at the worlds, dating to 1983, but none before Tuesday night had come in an event shorter than 800 meters.

Tuesday night’s winner: Kenya's Nicholas Bett, in a national record and 2015 world-leading time, 47.79. From Lane 9, again far on the outside.

“I am happy to win this first 400-meter hurdles medal ever for Kenya,” Bett said afterward. “I am thankful.”

Russia’s Denis Kudryavtsev, in 48.05, took one-hundredth off a national record that had stood for 17 years.

Jeffrey Gibson of the Bahamas ran a national record 48.17. That broke his own record, 48.37, which he had run in the semifinals.

“I am looking forward to more races and more training for the Olympic season,” he said afterward.

It must be acknowledged, as the New York Times pointed out in a story after Tuesday's finals, that U.S. coaches are playing a significant role in the success of other nations, and in events, such as the long jump, where memories of American success — Carl Lewis, Mike Powell, Dwight Phillips — run long.

In Tuesday night’s long jump final, the gold (Britain’s Greg Rutherford) and silver (Australian Fabrice Lapierre) medals went to athletes who train near Phoenix with the American Dan Pfaff; the bronze, China’s first long jump medal at a worlds, went to Wang Jianan, who trains with the American Randy Huntington.

The top American? Jeff Henderson, the 2015 Pan Am Games champion, ninth, one spot out of the finals.

Barber, the Canadian pole vault winner? He goes to college at the University of Akron.

As in any meet, injuries always play a role. The American 200-meter specialist Wallace Spearmon, for instance, scratched out of Tuesday’s heats upon reporting a small tear in his left calf muscle.

Beyond all that, it’s track and field, and stuff happens. Alysia Montaño, one of the best American racers in the women’s 800, in contention for a top-three finish in Wednesday’s heats, fell on the second lap after a tangle. She ended up getting disqualified.

In Tuesday night’s women’s 1500, Jenny Simpson, the Daegu 2011 gold and Moscow 2013 silver medalist, lost a shoe. She finished 11th. Ethiopia’s Genzebe Dibaba, one of the sport’s brightest new stars, won in 4:08.09.

Hopes were high in the men’s steeplechase Monday night that, for the first time ever at a world championship, the Americans — specifically, Evan Jager — might win a medal. Jager led at the bell lap but finished sixth. The Kenyans went 1-2-3-4.

How, meanwhile, to explain the men’s triple jump?

Two Americans, Marquis Dendy and Will Claye, could not summon enough Wednesday morning to make the final.

Coming in, Dendy had the year’s fourth-best jump, Claye the fifth; Claye, moreover, is an incredibly versatile athlete who at the 2012 London Games became the first man since 1936 to win medals in both the long jump (silver) and the triple jump (bronze).

Wendy, afterward: “I can’t be too, too mad, but I am disappointed.”

Claye: “I’m still in shock. I don’t even know what happened. It just wasn’t my day. That’s the only way I can see it. I went out there and gave it my all. It just wasn’t my day. I have to make my rules and get ready for next season.”

Kenya super, US again kryptonite in steeple

BEIJING — Amid keen anticipation that this would finally be the year an American man would medal in the steeplechase at the world championships, Evan Jager headed into the bell lap in the lead.

And then came a fleet of Kenyans. Jager could not keep up. The Kenyans went 1-2-3-4, the master Ezekiel Kemboi winning in 8:11.28.

You’d say it was incredible but, for about 30 years, this is what the Kenyans have been doing in the steeplechase.

The Americans could take some consolation in a 5-6 finish — Daniel Huling passing a weary Jager down the homestretch for fifth.

Or you might say that the steeplechase is, for some inexplicable reason, the American track and field version of kryptonite, for generations now warding off any and all big-meet success.

Or it’s like the summer sport version of biathlon. Lots and lots of smart people, hard work, real promise — and then, regrettably, nothing.

To quote Bruce Springsteen, how can a poor man stand such times and live?

“Our plan was to go for gold, silver and bronze,” the second-place finisher, Conselsus Kipruto, said afterward. “I am happy that I was able to assist my team. I sacrificed myself for the team. We have a lot of experience but we are still young. Now we want to prepare well for the Olympic Games next year.”

Brimin Kipruto, in third, said, “We could not hope for a better result. I am so proud of my country and my team.”

In other action Monday, the U.S. woman recorded a best-ever finish in the 10k, 3-4-6, Emily Infeld going by Molly Huddle at the line for third; Shalane Flanagan took sixth. Infeld’s third matched the best American worlds finish in the event, Kara Goucher’s Osaka 2007 bronze.

Goucher may be in line for an upgrade to silver for that 2007 race. The second-place finisher, Turkey’s Elvan Abeylegesse, has been linked in recent weeks to doping reports.

Kenya’s Vivian Cheruiyot took gold Monday night, in 31:41.31, Ethiopia’s Gelete Burka silver, 46-hundredths back. Huddle appeared to celebrate too early, raising her arms as she approached the line, Infeld kept going. Infeld: 31:43.49, Huddle nine-hundredths behind.

Colombia’s Caterine Ibarguen affirmed her standing as the world’s best female triple jumper, winning in 14.09 meters, or 46 feet, 2-3/4 inches.

The men’s pole vault saw a shocker: 21-year-old Canada’s Shawn Barber, the 2015 Pan-Am Games champion who attends the University of Akron, winning with a jump of 5.90 meters, or 19 4-1/4. Germany’s Raphael Holzdeppe, the Moscow 2013 champion, took second, at the same height. Renaud Lavillenie of France, who has for the past several years dominated the event, finished in a three-way tie for third, at 5.80, or 19 0-1/4.

And, finally, in the women’s 100, the stellar Jamaican Shelly-Ann Fraser-Pryce, twice an Olympic champion, the reigning world champion at 60 meters, 100, 200 and in the 4x100 relay, did it again. She overpowered a strong field to win in 10.76, green hair flowing behind her, right arm up in triumph as she crossed the line.

The former heptathlon standout Dafne Schippers of Holland took second, in a national-record 10.81. American Tori Bowie got third, in 10.86.

Fraser-Pryce in the 100 at major championships: 2008, 1. 2009, 1. 2011, 4. 2012, 1. 2013, 1. 2015, 1.

"My message always is: no matter where you are from, no matter which past you have, it is all about your future and your goals," Fraser-Pryce said afterward.

A few moments later, she said, "When I ran the heats, I remembered when back in 2008 at the Olympic Games, I was 21 years old -- I expected nothing then. And I came out here tonight -- with a gold medal. Every championship is different. I am really excited."

Two notes of intrigue from the field in that women’s 100: the Jamaican Veronica Campbell-Brown, with seven medals across four Olympics, including three golds, finished fourth, in 10.91. And Nigeria’s Blessing Okagbare, who excels in both the sprints and the long jump, ended up last, in 11.02.

In the American camp, meanwhile, there had been such considerable hope before the men’s steeplechase that Monday, finally, be the night.

Some history:

With the exception of two wins — Paris 2003, Helsinki 2005 — by Saif Saaeed Shaheen representing Qatar, a Kenyan runner has won every worlds steeplechase since Tokyo 1991.

For those not up to speed on the details of the sport, Shaheen was born in — Keiyo District, Kenya. As Stephen Cherono, he ran for Kenya until 2002; he still holds the world record, 7:53.63, set in September 2004 in Brussels.

Every year, worlds or Olympics, the Kenyans seemingly just re-load.

Jairus Birech came into Monday night’s final as the world No. 1, winner of the final six Diamond League steeples in 2014 and three more this year. He has a 7:58.83 to his name.

Consensus Kipruto, the Moscow 2013 silver medalist, had been the only guy to have beaten Birech this summer — in London on July 25. He’s only 20 years old.

Brimin Kipruto is the 2008 Olympic champion (he fell on the sixth lap in London in 2012). Four years ago, at the Monaco Diamond League meet, he missed the world record by one-hundredth of a second. This year, he had run 8:10.09, No. 5 in the world.

And then there is Kemboi.

Kemboi is now 33. He used to be Shaheen’s apprentice.

But for nearly a decade he has been the master of the steeplechase.

Kemboi finished second at the worlds, behind Shaneen, at Helsinki and Paris and then again, behind another Kenyan, Brimin Kipruto, at the Osaka 2007 worlds.

He won at the 2004 Athens Olympics (8:05.81, a Kenyan sweep, Kemboi, Brimin Kipruto, Paul Kipsiele Koech).

Kemboi finished seventh in 2008 here at the Bird’s Nest, his worst international performance.

At major meets since, Kemboi has since been virtually unchallenged — winning the last three world championships, in Berlin 2009 (8:00.43), Daegu 2011 (8:14.85) and Moscow 2013 (8:06.01).

He also won at the London 2012 Summer Games (8:18.56).

Kemboi is not just a winner. He is what you might gently call a character.

After he won in Moscow, for instance, amid a dance-filled victory lap, he showed off his Mohawk haircut and a message on his T-shirt that said his victory was dedicated to the Kenyan president and deputy, “my heroes/my kings/I love Kenya.”

In Daegu, he partially shaved his hair. After he won, he threw his singlet into the stands and took his victory lap with the Kenyan flag tied, sweatshirt-style, around his waist.

In 2002, after winning his first major medal, a silver at the Commonwealth Games, Kemboi was so moved that he named his son (he is now the father of two boys) after the venue: Manchester.

And so on.

As a retort of sorts, Jager has a blonde man-bun.

The Kenyan domination over the years in the steeplechase has been matched, if you will, by American futility.

The American medal record in the steeplechase at the Olympics — in all, five:

Silver, 1920 (Patrick Flynn); bronze, 1932 (Joe McCluskey, and a historical note, in 1932 the race was 3460 meters long, not 3000); gold, 1952 (Horace Ashenfelter, who worked for the FBI and beat the Soviet Vladimir Kazantsev for the win, the only U.S. gold in the event); bronze, 1968 (George Young, behind two Kenyans); and bronze, 1984 (Brian Diemer, the winner, Julius Korir, of course Kenyan).

The American medal record at the world championships: zero.

Again, dating to the first world championships in Helsinki in 1983: zero.

Diemer took fourth at the edition in Rome in 1987.

Overall, before Monday night, Kenya at the worlds: 25 of 42 medals. United States: only seven guys to finish, ever, in the top eight.

As recently as four years ago, the United States did not qualify a single guy for the steeplechase final at Daegu.

Three guys then emerged:

Donn Cabral, the 2011 NCAA champ from Princeton; the next year, he dropped 12 seconds off his personal-best.

Dan Huling, 10 seconds off the final time qualifier in Daegu, endured a dismal two years — he didn’t break 8:20 from 2011 to 2013 — but came back strong this year. His last two races: 8:14 and 8:15.

Two years ago in Moscow, meanwhile, Jager took fifth.

In Paris earlier this summer, Jager set an American record, 8:00.45; he looked set to break eight minutes, saying afterward he thought he was on 7:56 pace, but while ahead fell over the last barrier.

The race is designed to be a physical and mental test. There are 28 hurdles, four each lap, and seven water jumps, one per lap. For those super-interested in the IAAF technical manual, the water depth at the barrier must — repeat, must — be 50 to 70 centimeters, 19.7 to 27.6 inches.

Why is the race called the “steeplechase”? Because, as the story goes, it was first run from the church steeple in one village to the church steeple in the next village.

Saturday’s heats underscored the different ways the race can play out — fast, slow, tactical or not.

— One, Conselsus Kipruto won in 8:41.41. Jager, fifth off the final turn, had to turn on the burners to finish second, one-tenth back. The European champion, France’s Yoann Kowal, took fourth — out of the finals.

If Jager had run just 15-hundredths of a second slower, he would have been out — watching the final on TV or somewhere.

— Two, a much-faster heat. The leaders reached two kilometers in 5:43.18, more than 20 seconds faster than heat one. Birech won, in 8:25.77, followed by Bilal Tabti of Algeria and Cabral.

— Three, Kemboi sat back and waited until the last 200 meters, then kicked to victory in 8:24.75, followed by Brahim Taleb of Morocco and Brimin Kipruto.

The strategy going into the final looked straightforward: four Kenyans against the one American, Jager.

They went through the first 1k in 2:49, Cabral second, Jager fourth, Conselsus Kipruto in front.

At 2k, it was Conselsus Kiputo at 5:36.77, Cabral 12th, Jager cruising along in the pack at 10th.

At the bell lap, it was 7:14.07, and Jager in front.

And then the Kenyans took off, as if lit by rocket fuel, and Jager faded.

Kemboi’s last lap made for what would have been an incredible stand-alone 400 hurdles. He sprinted to the finish in 8:11.28.

Consensus Kipruto took second, a tenth of a second back.

Sixteen-hundredths behind that, Brimin Kipruto.

Fourth: Birech, eight-hundredths out of the medals.

Jager could not keep up the pace. He slipped to sixth, 8:15.47.

Huling passed him down the homestretch. He grabbed fifth, in 8:14.39.

Afterward, Kemboi again wrapped the Kenyan flag around his waist and danced. Ever-so-briefly. And he kept his shirt on.

Kemboi now in major meets: 2003, 2. 2004, 1. 2005, 2. 2007, 2. 2008, 7. 2009, 2011, 2012, 2013, 2015: 1.

Huling would say later that his race aim was “sixth or seventh,” a medal “probably outside my talent level, my fitness level, obviously.

“So I wanted to run for sixth to seventh and if I did that and it gave me the opportunity to pick off someone, unfortunately, like Evan. I’m really gutted for him, I really wanted for him to get a medal. He probably spent a lot more energy to try and get a medal today. He probably had a better race than me.”

Jager, referring to the Kenyans, said, “Those guys are so freaking tough over the last lap, running extremely fast over barriers. It’s something that I haven’t figured out yet; I’m working on my entire career how to handle that. It’s definitely different than having a fast last lap in the flat race. It’s just a different element to it. There’s a reason why the Kenyans have won every single steeple world championships they’ve competed in the last 12-13 years. So it’s really tough. I have to figure out something for myself.”

He also said, "I’ll go back to the drawing board.”

Kemboi, meanwhile, got to bask in victory, as ever: “I am so happy about my fourth consecutive world title. It was a strong race. We maintained the pace but I never went in front — only [over] the last 400 meters.”

He also said about that killer kick, “On the last lap nobody could follow me. I will be celebrating tonight with my teammates.”

The sensation Brianna Rollins

It's an unusual thing, indeed, when Usain Bolt storms to victory -- this time, in the 200 meters -- and he is not the star of the show on an action-packed night at the world championships at Luzhniki Stadium in Moscow. That would be the new sensation of the women's 100 meter hurdles, Brianna Rollins of the United States, who -- in a race that many track aficionados had been looking forward to as the showdown of the meet -- came from behind to defeat the reigning Olympic champion, Sally Pearson of Australia.

Rollins' winning time: 12.44.

Pearson's: 12.5 flat.

Ponder this:

Rollins has made herself, in one year, NCAA champion, U.S. champion and, now, world champion. She finished up at Clemson this spring. She turns 22 tomorrow. She has now won 34 straight races, including heats, across four different disciplines.

Rollins ran an American-record 12.26 to win the U.S. outdoors in June. That 12.44 is her third-fastest time of the year even though it was run into a slight -- 0.6 meters per second -- headwind.

"I'd call it a great year for me," Rollins said. "I'd call it a blessed year."

As Benita Fitzgerald Mosley, the 1984 Los Angeles Games 100 hurdles gold medalist, now the U.S. Olympic Committee's chief of organizational excellence, put it in a telephone interview, Brianna Rollins "is something else -- she really is."

As for Bolt, who had dropped a starting block on his foot in the 200 heats but then got himself taped up and ran, anyway:

Sitting in the blocks, now his style, he got off to the slowest start in the field but nonetheless, as usual, had the race won by the curve. He eased up and still finished in 19.66.

By anyone else's standards, 19.66 would be extraordinary.

For all the understandable to-do about what Bolt does in the 100, the 200 always has been his best event.

To show how he has re-ordered time: 19.66 is his 10th-best 200 mark. Of course he holds the world-record in the event, 19.19, set at the 2009 world championships in Berlin.

Jamaica's Warren Weir, the London 200 bronze medalist, took second, in 19.79.

American Curtis Mitchell prevented a Jamaican sweep by coming on hard in the final 50 meters, finishing in 20.04 for third.

This is how close it was for third: Jamaica's Nickel Ashmeade crossed in 20.05 for fourth.

It was the first time in 200 history that all eight guys went a wind-legal 20.37 or faster.

Some more facts and figures to underscore not only Bolt's place in the record books but his hold on the imagination:

-- He became the first to win the 100-200 sprint double twice at the world championships.

-- His third 200 worlds gold surpasses Michael Johnson and Calvin Smith.

-- He now has seven world gold medals to go with the six he has won at the Olympics. A presumed eighth, the 4x100 relay, is coming up Sunday.

Pearson came into the women's 100 hurdles after overcoming an early-season hamstring problem. She ran 12.62 in the heats, then threw down a 12.5 in the semifinal, the fastest qualifying time, signaling that she was indeed ready to go.

Make no mistake: Sally Pearson is a big-game racer.

Rollins ran 12.55 in the heats, 12.54 in the semifinals.

This would be, of course, Rollins' first major international final. Also in Saturday's final: Dawn Harper, the 2008 Beijing gold medalist and 2012 London silver medalist.

In the first half of the race, it looked as if Pearson might just pull it off.

Rollins reacted horribly to the gun, 0.263. Pearson, meanwhile, got off to a good start, 0.154, and led through the first few hurdles.

But Rollins eventually made her move, passing Pearson over the eighth and ninth hurdles.

With the victory, Americans won both the women's and men's sprint hurdles at the worlds for the third time; David Oliver won the men's 110 hurdles on Monday. Americans won previously in 1995 and 2001.

"Today I didn't have the best start but I didn't panic," Rollins said. "I was just focusing on my own lane and working hard, trying to finish strong. Today was about the victory, not about the time. The fast times will come. I have a huge respect for Sally Pearson. She is a great athlete and it was great to compete with her today. I was nervous but nervousness is normal. It's just about the way you handle it."

For her part, Pearson said, "Of course you are going to a race to win but I am satisfied. It is not gold but the best I could produce tonight. It was a hard year for me. In July, others were smashing me. Tonight I was only beaten by one. Next year, I won't be getting any silver!"

Great Britain's Tiffany Porter ran a personal-best 12.55 for third place, Britain's first women's 100 hurdles medal at a world championships. Harper took fourth in 12.59, with another American, Queen Harrison, fifth in 12.73.

"It was a horrible race, and I don't know what happened," Harper said.

In other action, the illustrious Meseret Defar of Ethiopia won the women's 5000 meters, in 14:50.19, the fastest time in the race at the worlds in eight years -- despite a last 200 meters run in a relatively pedestrian 29.43.

Defar is 5-foot-3, 92 pounds of tough. Her record:

Three Olympic 5k medals -- 2012 and 2004 gold, 2008 bronze.

Five worlds 5k medals, a record -- two golds, one silver, two bronze.

In her typically understated way, Defar said afterward, "It is a big achievement for me."

Molly Huddle finished sixth in 15:05.73, the best finish ever by an American.

The U.S. women's 4x400 relay team's world championship winning streak -- five -- came to an end. Russia won, in 3:20.19. The Americans -- running without the injured Allyson Felix -- took second, in 3:20.41. Great Britain came in third, in 3:22.61.

In the women's high jump, Russia's Svetlana Shkolina, the 2012 bronze medalist, took gold Saturday at 2.03 meters, or 6 feet, 8 inches. American Brigetta Barrett, the London silver medalist, took second again; she cleared 2.00, or 6 6-3/4, but not 2.03.

"Two silver medals in the course of 12 months -- it's been one heck of a year," Barrett said later.

Finally, this:

Kenya's previous best performance at the worlds in any field event had been 15th in the triple jump qualifying.

In the men's javelin, won by the Czech Republic's Vitezslav Vesley with a throw of 87.17 meters, or 286 feet, Kenya's Julius Yego took fourth. He threw a national-record 85.40, or 280-2.
