Justin Gatlin beats Bolt in his last 100m

Athletics - World Championships 2017

Justin Gatlin defeated Usain Bolt in the Jamaican’s last 100m competition.

In a pulsating 100m final in a packed Olympic stadium in London, Justin Gatlin clocked 9.92 to become world champion.

Another athlete from the United States Christian Coleman pipped Bolt for the silver meadl with 9.94.

Usain Bolt had to settle for third place with 9.95 seconds.

Andrius Gudzius of Lithuania won his first major discus title, holding off favorite Daniel Stahl of Sweden by only 2 centimeters at the world championships.

Gudzius threw 69.21 meters on his second of six attempts, while the Swede finished just short. Mason Finley of the United States took bronze.

Defending champion Piotr Malachowski of Poland finished fifth.

Almaz Ayana is turning massive victories into a tradition.

The Ethiopian produced the biggest one of all in the 10,000 meters at the world championships in London.

After winning the Olympic title in Rio de Janeiro with a runaway world record, she made sure that her margin was even bigger at the worlds — make that three times as big.

Ayana won in 30 minutes, 16.32 seconds, 46.37 seconds ahead of Ethiopian teammate Tirunesh Dibaba. In track terms, that is more than 300 meters in a 10-kilometer race. Agnes Tirop of Kenyua took bronze.

Ayana came into the championships swirled in mystery. She had no official time for the 10,000 this season and had been hampered by injury.

South Africa’s Luca Manyonga obtained the medal with a jump of 8.48m.

The silver medal went to Jarrion Lawson of the United States who managed a jump of 8.44m.

Another South African, Ruswahl Samaai won the bronze with a jump of 8.32m.

Olympic champion Jeffrey Henderson, who beat Manyonga by one centimeter in Rio de Janeiro, failed to qualify for the final.

Defending champion Genzebe Dibaba skirted a major upset in the semifinals of the 1,500 meters, finishing sixth in her heat with only five automatic qualifiers at the world championships.

The Ethiopian had to wait until the results of the second semifinal heat came through and qualified when her time was among the top two of the non-automatic qualifiers.

Dibaba was still in the mix with 200 meters to go in her race but instead of producing her devastating final kick, she faded.

Faith Kipyegon of Kenya and Caster Semenya of South Africa both advanced from the same heat.

Van Niekerk is seeking to win gold in both the 400 and 200 meters over the next week. He is tipped by many to become the sport's next star now that Bolt is retiring after the world championships.

In both races, though, he might find his toughest rival in Isaac Makwala of Botswana. Makwala was just as good in his heat. Following a fast start, it was a jog in the finishing straight as he finished in 44.55 for the top time of the day.

The two are equally tight competitors in the 200, too, yet there is no bitterness in their rivalry.

"Wayde van Niekerk is my brother," Makwala said. "We want to conquer the world together and make the final for Africa. He is so friendly and a lovely guy."

The pair dominated the morning session at the Olympic Stadium, but by dusk, all eyes will be on Bolt as he tries to bow out with a last individual gold in the 100 meters.

The two-day heptathlon also started and after two events Olympic champion Nafi Thiam took the lead. She scaled 1.95 meters in the high jump to reach a total of 2,215 points.

In a battle of 22-year-olds, Yorgelis Rodriguez matched Thiam in the high jump with an incredible 8-centimeter improvement of her personal best to keep in touch in the overall standings with 2,207 points. Caroline Schafer of Germany was third with 2,165.

One of Thiam's toughest rivals, Katarina Johnson-Thompson, only cleared 1.80 in the high jump, well short of her best of 1.98, to dent her gold-medal hopes. She was in fifth position with 2,053 points.

In the women's 100, all the favorites advanced to the semifinals despite a downpour that affected many of the runners.

Twenty-year-old Gina Luckenkemper of Germany, who raced before the rain came, had the top time of 10.95 seconds. She was the only woman to break the 11-second mark.

Olympic champion Elaine Thompson of Jamaica easily won her heat in 11.05, while Dafne Schippers of the Netherlands had more of a struggle finishing second to Marie-Josee Ta Lou of Ivory Coast. Ta Lou had the second-best time of 11.00.

Tori Bowie of the United States got the worst of the rain but still looked very strong as she took her heat in 11.05.

The semifinals and final are set for today.
