The American, however, could only managed a mere 10.13 seconds to win the men’s 100 meters at the meeting.
Japan’s pair of Masashi Eriguchi and Naoki Tsukahara both clocked 10.31secs for second and third, respectively.
“I didn’t get the time I wanted,” Gay said. “They said it was a positive wind but it felt more like a headwind because I felt the wind blowing in my face. I don’t know if it was a swirl or crosswind.”
Gay was stunning on Sunday in Shanghai when he equaled the second-fastest time for the 100, when posting a time of 9.69 seconds to match Usain Bolt’s previous world record from last year’s Beijing Olympics.
Bolt has since beaten that mark, running 9.58 at last month’s world championships in Berlin. Gay was second in 9.71.
Three time world 200m champion Allyson Felix of the United States won the women’s race with a time of 11.22.
“I didn’t know what to expect because it’s been about two months since I ran the 100,” Felix said. “I was a bit rusty and was going through the motions a bit.”
Meanwhile, Canadian Perdita Felicien won the women’s 100m hurdles in 12.74secs and Jamaica’s Dwight Thomas ran 13.37 for the men’s 110m hurdles.
Former world and Olympic champion Felix Sanchez of the Dominican Republic won the men’s 400 hurdles in 48.91, while American Tiffany Williams took the women’s event in 55.31secs.
“This year has been difficult because my rhythm has been off, but I’m starting to find my form,” Sanchez said. “I’m getting my confidence back and, hopefully, I can build on this.”
Elsewhere, Congo’s Gary Kikaya won the men’s 400m in 45.73, while USA’s Reese Hoffa won the men’s shot put with 20.21m.
