World track and field championships: Dafne Schippers wins 200m in record time
Former heptathlete denies Jamaica its 4th sprint gold
Dafne Schippers completed an incredible switch from heptathlete to sprinter by winning the 200-metre world title Friday, denying Jamaica its fourth gold medal in the two fastest races on the track.
Two years after winning bronze in the punishing seven-event discipline, she swept past Jamaican sprinters Elaine Thompson and Veronica Campbell-Brown with a perfect dip for the line to add gold to the silver she won in the 100.
She crossed in 21.63 to beat the 28-year-old championship record by 0.11 seconds.
Canada's Nettey just misses long jump medal
Tianna Bartoletta won her second long jump world title, 10 years after her first.
The American took the lead for the first time in the final when she jumped 7.14 metres with her last attempt.
Shara Proctor of Britain took silver with a best mark of 7.07 metres, and Ivana Spanovic of Serbia was third at 7.01.
Canada's Christabel Nettey placed fourth with a jump of 6.95.
Canada's Warner trails Eaton in decathlon
Ashton Eaton, coming back after a two-year absence, needed only 10.23 seconds to establish himself again as the favourite to win the decathlon. That's how long it took the American to run the 100 metres in a championship decathlon record on Friday at the start of the two-day competition.
And at the end of the first day, he set a world decathlon record over the 400 meters to show he is in shape to challenge the overall world record in the 10-event discipline on Saturday.
He finished the 400 in 45.00 seconds, slashing 0.68 seconds off the mark he shared with 1968 Olympic champion Bill Toomey.
Eaton also won the long jump with a leap of 7.88 meters, and then had good showings in the shot put and high jump to put him in a dominating position after five events.
Eaton leads with 4,703 points, 173 points more than Damian Warner of Canada.
Jamaica's Williams wins 100m hurdles
Danielle Williams won the 100-metre hurdles in 12.57 seconds in a final that didn't feature an American in the top three.
The 22-year-old Jamaican held off Cindy Roleder of Germany, who won silver in 12.59. Alina Talay took bronze in a Belarus record 12.66.
Defending champion Brianna Rollins of the United States was fourth in 12.67, 0.01 ahead of European champion Tiffany Porter of Britain.
Sharika Nelvis, who had the fastest time of the season and was a medal contender for the United States, placed last in the final.
Dawn Harper-Nelson, the 2008 Olympic champion, crashed in the semifinals.
Shubenkov takes men's hurdles
Sergei Shubenkov lunged late to win the 110-metre hurdles final in a Russian record 12.98 seconds.
Hansle Parchment of Jamaica took silver in 13.03, edging Olympic champion and world-record holder Aries Merritt of the United States by 0.01.
Merritt, who has a kidney condition which will require a transplant early next week, took the bronze.
