Gay starts in 400 m
Tyson Gay returned to the track. The 2007 World Champion competed for the first time since Gateshead Meeting on August 31 last year (20.26 win at 200 m).
At Sun Devil meet in Arizona he won the 400 m in his first ever outdoor race at the distance and clocked solid PB 46.34. To compare with other top sprinters Usain Bolt achieved this year 45.54 (but has 45.28 PB) and Asafa Powell improved in 2009 to 45.94.
