Tyson Gay, back on the track hours after his world leading 9.75 seconds in the 100 meters, comfortably advanced through the opening round of the 200 meters at the U.S. world championships trials in Des Moines, Iowa on Saturday.
"I am not trying to be Superman," said Gay, who clocked a wind-assisted 20.14 seconds in his bid to run a sprint double at the August 10-18 championships in Moscow.
Although he managed only a couple hours' sleep after his speedy 100 meters win over Olympic bronze medalist Justin Gatlin, Gay told reporters: "After I warmed up this morning I decided to go ahead (and run) because I am healthy. That's the key."

The 200m semi-finals and finals are on Sunday, the concluding day of the meeting.
