Tyson Gay warmed-up perfectly for the London Olympics by winning the 100 metres in the London Grand Prix in Crystal Palace.
Gay, one of the main contenders for the 100M title in the Olympics, stormed home in 10.03 seconds into a headwind of 1.2 metres per second. Fellow American Ryan Bailey finished second with Jamaica's Nesta Carter taking third.
"I'm in pretty good shape, I just need to work on some things on my groin area with my physio and I should be good to go," Gay said.
"I feel I know how to mentally prepare for this type of weather, and this was the best place to prepare for the Games."
Gay, the second fastest man in the world, will look to win his first Olympic gold medal in London when he takes part in one of the toughest, most competitive 100 metres in years. The 29-year-old will compete against Usain Bolt, who pulled out of this event due to tax reasons, Yohan Blake, Asafa Powell, missing because of a groin strain, and Justin Gatlin for the most coveted medal in the summer showpiece.
In the 110 metre hurdles, Aries Merritt won the gold in 12.93 seconds, after 2004 Athens Olympics gold medallist Liu Xiang pulled out of the finals due to a back injury.
"The conditions were the same for all of us and this will be great preparation for the Olympics if the weather is like this," said Merritt.
"I got here just two days ago so I am a little under the weather as far as my sleeping patterns are concerned. So it's amazing that I am running this well, I can't be more excited.
"I have to do it when it counts -- this means nothing if I can't do it at the Olympics."
Mo Farah established himself as the clear favorite for the Olympic crown, with a comfortable win in the 5000 metres in 13 minutes, 6.04 seconds.
"I'm in great shape," Farah said after the race. "It was important to work on my speed a bit.
"Conditions were not great, but, I'm looking forward to the Olympics. It's not long to go.
"I just have to think of it as another race and forget it's the Olympics, but I'm quite looking forward to it."
