Former world champion runs his fastest time of the year, while Sherika Nelvis goes seventh all-time in the heats of the women’s 100m hurdles

US record-holder Tyson Gay beat new star Trayvon Bromell in the final of the 100m on day two at the US Championships.

Gay clocked 9.87 to finish nine hundredths in front of runner-up Bromell, who had run 9.84 in the heat. Mike Rodgers took the third automatic qualifying spot with 9.97. The wind was legal at 0.0m/sec.

Earlier Bromell was quickest in the semi-finals with a windy 9.76 to beat Gay’s 9.79, assisted by a gust of 3.7m/sec.

Justin Gatlin, the fastest in the world this year, is concentrating on the 200m, which begins Saturday, as he already has a bye to compete at the Worlds in the 100m as last year’s Diamond League winner.

However, arguably the performance of the day came in the heats of the women’s 100m hurdles where Sharika Nelvis went to seventh on the world all-time list with 12.34. The wind was an almost ideal 1.9m.sec as the 25-year-old took 0.18 off her PB. The second quickest in the heats was Keni Harrison with a wind-aided 12.46, while also windy was the 12.47 by former world No.1 Jasmin Stowers. World champion Brianna Rollins was only seventh quickest and may value her automatic bye to compete at the World Championships.

In the final of the women’s 100m, Tori Bowie went to third on the world list for 2015 with 10.81 to beat English Gardner (10.86) as Jasmine Todd was third (10.92) with a 1.2m/sec following wind. Gardner had clocked a world lead of 10.79 in the semi-finals.

Twice world champion Trey Hardee topped the year’s rankings in the decathlon with 8725 as he easily overcame the rest of the field. Olympic champion Ashton Eaton, who has a bye for Beijing as world champion, did not compete.

Erik Kynard won the highest-quality field event of the day, high-jumping 2.37m. JaCorian Duffield was second with 2.34m and Jesse Williams third with 2.31m.

The javelin title went to Kara Winger with 64.94m and Christina Epps won the triple jump with 14.09m.

Building up to a highly anticipated women’s 800m final, a time of 2:00.48 was not quick enough to go through from the semis as Chanelle Price was fastest with 2:00.05.

Francena McCorory was quickest to proceed from the semi-finals of the 400m, clocking 49.85. Olympic 200m champion Allyson Felix also qualified, having a bye for the half-lap event as 2014 Diamond League winner.

World champion Lashawn Merritt went safely through to the final of the 400m behind David Verburg, the quickest at 44.41, but twice world champion Jeremy Wariner went out, running only 45.90.
