Gay, trailing out of the blocks, exploded near the midway point and powered home to win in the fastest time in the world this year.
Justin Gatlin, the 2004 Olympic gold medallist who handed six-time Olympic champion Bolt a rare defeat in Rome this month, just couldn’t match Gay in the closing stages. Running warily with a mild right hamstring strain, Gatlin finished second in 9.89.
Charles Silmon seized the third World Championships berth on offer by the narrowest of margins, finishing third in 9.98sec (9.972) with Michael Rodgers relegated to fourth by just two-thousandths of a second (9.974).
