Gay powers through to 100m title

EUGENE - Tyson Gay is back on top as America's 100 metres champion, but he had to run down teenager Trayvon Bromell for the honour at the US world championships trials on Friday.

The victory, in 9.87 seconds, returned the 32-year-old Gay to the world championships for the first time since 2009 and fans lauded him with a teddy bear, a book and some high fives during a victory lap.

Bromell, just 19, clearly had the jump on Gay early in the race but could not retain the advantage as the 2007 world champion powered to the lead and won by almost a tenth of a second.

"That kid - he's tough," Gay said of Bromell. "He got out good, it was just one of those 10 years of experience, dig-down moments I had to get him. It felt good though.

"This win right here may be (my) most important win. I feel like it was the toughest."

Bromell clocked 9.96 to become the first teenager to the make a US world championship team in the 100m.

Mike Rodgers claimed third in 9.97 seconds as he also won a ticket to Beijing.

Justin Gatlin, the year's fastest at 100m, has a bye for Beijing in the event and will compete only in the 200m at the trials. His first race is on Saturday.

Tori Bowie won the women's final in 10.81 with English Gardner the runner-up at 10.86.
