YOKOAHAMA — Track and field is an all-weather sport. But with Sunday's conditions the competitors could be forgiven for failing to post any convincing outcomes in an event in which nearly all the contests were hit by a steady, chilly rain.

But world champion Tyson Gay still got the job done, winning the men's 100-meter race by a large margin with a time of 10.23 seconds at The Seiko Super Track and Field Meet 2007 at Nissan Stadium in Yokohama on Sunday afternoon.

"It feels pretty good," said the 25-year-old American sprinter, who triumphed in the 100, 200 and 4x400 relay races in August's World Championships in Osaka. "The race was OK, considering the conditions."
