GATESHEAD, England -- Tyson Gay won his first race since a second-place finish at the world championships, then said he would be having surgery at the end of the season to cure a lingering groin injury.
Gay clocked 10.15 seconds running into a headwind at the British Grand Prix on Monday, finishing well ahead of Kim Collins and Marc Burns. It was Gay's first race since he was beaten by Usain Bolt's blistering performance in Berlin, where the Jamaican set a world record of 9.58 on Aug. 16.
"I'm looking forward to Brussels [Friday], maybe one more race and then we're going to get surgery," Gay said after finishing 0.29 seconds ahead.
"I felt great with my second-place finish [in Berlin]. I ran a great time, just wasn't fast enough."
Gay had a great start at Gateshead and was well away from the field by halfway to win by more than 2 meters. Collins, the 2003 world champion from St. Kitts and Nevis, was given second place ahead of Burns of Trinidad and Tobago, even though they had the same time of 10.44.
Olympic and world 400-meter champion LaShawn Merritt won his 15th race in a row but clocked a slow 45.11 seconds in the damp and blustery conditions, ahead of Britain's Martyn Rooney with Angelo Taylor third. Kerron Clement, the two-time 400-meter hurdle world champion from the U.S., placed sixth in 45.77.
"I'm feeling great," Merritt said. "I had a great season last year -- won Olympic Games. Came to this year and my main focus was the world championships. I got there, took it through the rounds, got to the final. I'm world champion now.
"I ran in Zurich two days ago and ran 44.2, second-fastest time in the year. I just want to finish my season off."
Shawn Crawford, the 2004 Olympic champion, held off Wallace Spearmon to win the 200 meters in 20.80 seconds.
American sprinter Carmelita Jeter won the women's 100 meters, running 11.08 seconds into a strong headwind. Countrywoman Allyson Felix, the three-time world champion, recovered from a poor start to cruise to an easy but slow victory in the 200 in 23.13.
World champion Brigitte Foster-Hylton of Jamaica pulled away to win the 100 hurdles in 12.88.
Bernard Lagat was surprisingly beaten in the 3,000 meters by Moses Kipsiro of Uganda.
