Gay clocks second best 100m ever

Tyson Gay equalled the second fastest time ever over 100m with 9.69 seconds at the Shanghai Golden Grand Prix. The American has struggled with a groin injury of late but still won a Worlds silver medal behind Usain Bolt. At China's end-of-season meet, Gay, 27, equalled the world record Bolt set when he won Olympic gold last year before he reduced it to 9.58 secs in Berlin. Gay, who has been suffering from a strained groin and is set to have an operation, admitted at the start of the month he had been "running on one leg". After running the third-fastest 100m in history, 9.71, at the World Championships, where he had to pull out of the 200m, Gay beat Jamaican Asafa Powell by 0.16s in China with American Darvis Patton in third (9.89).

American Carmelita Jeter ran 10.64 secs to overtake Marion Jones as the world's second fastest woman over 100m. Only the late Florence Griffith-Joyner has run faster having run 10.49s.
