June 21 (Reuters) - Veteran American sprinter Mike Rodgers cruised to the year's fastest 100 metres when the 33-year-old clocked 9.89 seconds in qualifying at the U.S. championships in Iowa on Thursday. The performance stole the show from America's younger generation of sprinters on the first day of the meeting that will decide the United States team for next month's Athletics World Cup in London.
Talented 20-year-old Noah Lyles had the second fastest time, 9.92 seconds, but unlike Rodgers, his run was wind-assisted, coming with an aiding wind of 3.4 metres per second.
The wind on Rodgers' race was 1.4 mps, under the allowable 2.0 mps.
Two others broke 10 seconds on the fast track at Drake University in Des Moines.
The 28-year-old Isiah Young won his preliminary race in 9.93 seconds while Cameron Burrell recorded the same time in finishing behind Rodgers.
Co-favourite Ronnie Baker, the world indoor 60m bronze medallist, was next in 10.00 seconds as he won his preliminary.
The previous best time for the year was 9.91 seconds by Britain's Zharnel Hughes. (Reporting by Gene Cherry in Raleigh, North Carolina; Editing by Greg Stutchbury)
