The day also saw the triumphant return of Tyson Gay in a B-level 100 race, a romp by 800m world champion David Rudisha and another failure to reach an Olympic time standard for South African Oscar Pistorius.
Blake battled back to edge Trinidad and Tobago’s Keston Bledman at the line in 9.90 seconds, winning by .03, with American Michael Rodgers third in 9.99 and 2008 Olympic runner-up Richard Thompson fourth in 10.09.
“I just wanted to keep a clean sheet going into the Olympics,” Blake said. “I feel a little disappointed. I wanted to do something better. Just one of those days.”
Blake, aided by a 0.7m/sec tailwind, will best tested by training partner Bolt, Asafa Powell and a host of rivals at the Jamaican Olympic trials in late June and says a Jamaican 100m Olympic podium sweep is “more than possible”.
