Olympic champion Justin Gatlin won the 100 meters in 9.89 seconds yesterday at the Crystal Palace meet in London, while world record holder Asafa Powell pulled up with a groin injury and could be in doubt for next month's world championships.

Russia's Yelena Isinbayeva cleared the five-meter barrier for her 17th world pole vault record, while Jeremy Wariner took a stunning defeat in the men's 400 and Veronica Campbell had her five-year winning streak snapped in the 200.

The men's 100 final was the first race between the world's top two sprinters since Powell set the record at 9.77 in Athens last month. But the highly anticipated matchup turned into a one-man show for Gatlin, who clocked the fastest 100 time ever in Britain.

Isinbayeva cleared 16 feet 31/4 inches, surpassing by a half-inch the record she set in Madrid six days ago. Then, she raised the bar to five meters (16-43/4) -- considered a landmark height -- and cleared it with ease on her first attempt.

In a major upset, Britain's Tim Benjamin beat Wariner -- the Olympic and U.S. champion -- in the 400. Benjamin won in a career-best 44.75. Wariner was second in 44.86.

American Allyson Felix blew past Campbell in the final 30 meters to win the women's 200 in 22.16, with Campbell second in 22.29.
