LONDON (AP) — The Latest from the world championships (all times local):
Tori Bowie won the 100 meters at the world championships and made it 2-0 for the United States over Jamaica in the battle for sprint supremacy.
Bowie threw her chest forward with a final lunge to nip Marie-Josee Ta Lou and win in 10.85 seconds. She beat Ta Lou by .01 seconds.
Once over the line, she fell on the track without a clue whether she had won gold.
"I had no idea," Bowie said.
Dafne Schippers, the 2015 world champion in the 200, took bronze in 10.96.
Two-time Olympic champion Elaine Thompson was a big favorite to add more gold for Jamaica but was never a factor and finished fifth in 10.98.
On Saturday, Justin Gatlin won the men's 100, beating Usain Bolt.
Tomas Walsh now has a shot put gold medal from the world championships to add to his Olympic bronze.
The New Zealander already earned gold when he threw 22.03 meters on his last attempt, 37 centimeters more than defending champion Joe Kovacs.
The American also had a huge throw on his last attempt but was given a red flag for a foot fault. Stipe Zunic of Croatia took bronze with a toss of 21.46.
Ryan Crouser of the United States, the Olympic champion and the season's top performer, never got it going and finished sixth with a throw of 21.14.
In another duel for gold, Ekaterini Stefanidi again held off Sandi Morris to claim pole vault gold.
Morris and Stefanidi were involved in an epic battle when the Greek won on a countback at the Olympics in Rio de Janeiro. It was almost as good at the world championships.
This time, neither had a failure through 4.75 meters — they were tied at the top with all opposition already out. Then, Stefanidi scaled 4.82 while Morris failed.
When gold was already assured, Stefanidi cleared 4.91 for a Greek record.
In a tie for bronze at 4.65, Robeilys Peinado got Venezuela's first-ever medal in the championships. She tied with 2015 champion Yarisley Silva of Cuba.
Nafi Thiam added a world championship gold medal to her Olympic title.
The 22-year-old Belgian already had a huge lead coming into the concluding 800-meter race in the two-day competition. Thiam finished last in the final heat but had more than enough points to win.
She finished with 6,784 points, 88 more than silver medalist Carolin Schaefer of Germany. Anouk Vetter of the Netherlands took bronze with 6,636 points.
Thiam, still only 22, won three of the seven events — the high jump, shot put and long jump.
Olympic champion Omar McLeod of Jamaica won the first semifinal heat in the 110-meter hurdles at the world championships.
Defending champion Sergey Shubenkov of Russia, competing as a neutral athlete, finished third and went through as the fastest non-automatic qualifier.
Aries Merritt, the 2012 Olympic champion, was second behind Balazs Baji of Hungary in their heat, but that was good enough to give him an automatic place in the final.
Wayde van Niekerk is the star of the 400 meters, but even he was forced to work hard to win his semifinal heat at the world championships.
The South African was trailing Baboloki Thebe of Botswana coming into the home straight and had to push to get ahead. Once there, the two briefly locked glances and turned down the power as they both automatically advanced into the final.
Thebe will likely not be the biggest threat from Botswana in the final since Isaac Makwala easily won his semifinal heat, too.
In the first heat, Steven Gardiner turned in a sub-44 second performance with a Bahamian record of 43.89.
Fred Kerley was the only American through to the final, finishing third in the opening heat and advancing only as the fastest non-automatic qualifier.
Olympic champion Elaine Thompson set the top time in the semifinals of the 100 meters.
Thompson won her heat in 10.84 seconds. Rosangela Santos of Brazil was second in a South American record of 10.91.
After Justin Gatlin beat Usain Bolt to get the United States first on the board in the great U.S.-Jamaican sprint rivalry, it will be up to Thompson to get even. The Americans have only one runner in Sunday's final, Tori Bowie. She won her heat in 10.91.
In the first heat, Marie-Josee Ta Lou of Ivory Coast finished in 10.87 to advance along with Dafne Schippers of the Netherlands.
Justin Gatlin came into the Olympic Stadium again, and sure enough, the boos were there again.
At the medal ceremony for the 100 meters, Usain Bolt received massive cheers for his bronze medal and American silver medalist Christian Coleman was also warmly greeted by the crowd of about 60,000 spectators.
However, when Gatlin came up to receive his gold medal from IAAF President Sebastian Coe, the derisive booing returned but there was also a smattering of applause — some of it from Bolt. The negative intensity didn't quite reach the peaks of the previous days when Gatlin ran.
With his doping past — his suspension ended in 2010 — the American has long been portrayed as the bad guy set against Bolt's charismatic, fun-loving personality.
Jessica Ennis-Hill received a massive ovation from the home crowd at the Olympic Stadium when she was given the gold medal for the 2011 heptathlon.
Ennis-Hill was promoted to first place in the event because Russian rival Tatyana Chernova was stripped of the title for doping.
The cheers brought back fond memories for Ennis-Hill, who won the 2012 Olympic gold medal in the heptathlon in the same stadium.
"It was truly incredible," the pregnant Ennis-Hill said.
It was the third and last day of such ceremonies recognizing athletes who were bumped up in the results after others were caught doping.
The IAAF has been retesting samples of athletes suspected of doping and annulling their result if they belatedly were shown to have been positive.
Rose Chelimo, a runner from Kenya now competing for Bahrain, pulled away near the finish to win the women's marathon at the world championships.
In a back-and-forth race, Chelimo held off two-time world champion Edna Kiplagat by seven seconds, with American runner Amy Cragg taking third. Chelimo finished in 2 hours, 27 minutes, 11 seconds.
Kiplagat barely beat a hard-charging Cragg.
Ronald Levy of Jamaica was a medal contender in the 110-meter hurdles but failed to make it into the semifinals after clipping the first hurdle with his trailing leg.
Levy had the third-best time in the world this year and also won the Diamond League meet in Paris. Despite a good clearance out of the blocks, he inexplicably hit the first hurdle hard and was so out of balance he came to a stop at the second obstacle. He left the track seemingly injured.
Aries Merritt of the United States, who won the Olympic title in London five years ago, easily went through with a top time of 13.16 seconds, .07 seconds ahead of reigning Olympic champion Omar McLeod of Jamaica.
Defending champion Sergei Shubenkov of Russia was also through as third finisher in his heat.
Nafi Thiam extended her lead with a strong showing in the javelin, the penultimate event in the heptathlon at the world championships.
With only the 800-meter race to go later Sunday, the Olympic champion has 5,980 points, 172 more than Carolin Schaefer of Germany.
If Thiam gets around the two laps of the Olympic Stadium without a serious incident, she should be able to add the world title to her Olympic gold.
Anouk Vetter of the Netherlands set a huge javelin mark of 58.41 meters to move into bronze medal position overall. Thiam was second with a throw of 53.93.
Geoffrey Kirui of Kenya won the men's marathon at the world championships with a come-from-behind run finishing on Tower Bridge.
The 24-year-old Kirui became the fifth Kenyan man to win the marathon title at the worlds.
Kirui cruised through the last portion of the race with little worry as he made his way across the finish line. He won in 2 hours, 8 minutes, 27 seconds, and was 1:22 ahead of Tamirat Tola of Ethiopia. Alphonce Simbu of Tanzania finished third.
Tamirat Tola of Ethiopia took the lead in the men's marathon near the halfway point of the race at the world championships.
Tola earned a bronze in the 10,000 meters at the Rio de Janeiro Olympics. He won a marathon in Dubai this season and a half-marathon in Prague.
Evan Jager of the United States was the top qualifier for the steeplechase final.
Jager is trying to break the 30-year stranglehold of Kenyan and Kenyan-born runners on the event.
Jager was in control all through and finished in 8 minutes, 20.36 seconds. The top Kenyan in Jager's heat was fourth and Ezekiel Kemboi, a four-time world champion and two-time Olympic champion, qualified only as one of the fastest finishers outside the three automatic qualifying spots.
The last runner who was born outside Kenya to win was Francesco Panetta of Italy at the 1987 world championships in Rome.
Olympic champion Nafi Thiam regained the lead in the heptathlon with only two events left at the world championships when she won the long jump with a leap of 6.57 meters.
With overnight leader Carolin Schaefer jumping only 6.20, the lead switched again between the two. Thiam now has 5,044 points, 96 more than the German.
After a bad start to the competition, Katarina Johnson-Thompson brought herself back into medal contention with a jump of 6.57. That put her into third place with 4,865 points.
The javelin and the 800 meters are the final two events.
The heptathlon enters its final day with Olympic champion Nafi Thiam and Carolin Schaefer in the chase for gold at the world championships.
Other finals on Sunday are the two marathon races, the women's 100 meters and pole vault, and the men's shot put.
After the Americans went 1-2 in the men's 100 meters with Justin Gatlin taking gold and reducing Usain Bolt to bronze, Olympic champion Elaine Thompson will be seeking to get one back for Jamaica. Tori Bowie leads the U.S. challenge.
The U.S. team could well win more medals with Ryan Crouser favored to add the world title to his Olympic shot put gold.
