• Gay Impresses With 9.75 at US Champs
Tyson Gay won the 100m at the US athletics championships in an impressive 9.75sec on Friday June 21 to put himself on top of the worlds season list.
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).
The top trio will spearhead the US challenge to six-time Olympic gold medallist Bolt and his fellow Jamaican sprinters at the World Championships in Moscow on August 10-18.
