ZURICH (AFP) A US quartet featuring Tyson Gay ran the fourth fastest time ever in the 4x100 metres relay at the Diamond League meeting here on Thursday. Trell Kimmons, who had earlier run 9.95 seconds in a 100m 'B race, teamed up with Gay, newly-crowned Diamond League 200m champion Wallace Spearmon and Michael Rodgers to clock a world lead and meet record of 37.45sec. Only Jamaica, in winning gold at the 2008 Beijing Olympics, and two previous US teams (in Barcelona and Stuttgart in 1992 and 1993 both 37.40sec) have gone faster. It was a lot of fun, one of the funniest moments of the season for me, beamed Gay, who had opted not to compete in the 200m. Im happy we got the stick around, that was the most important thing, he said in reference to the US quartet being disqualified from the 2009 worlds in Berlin and dropping the baton at the Beijing Games. Gay, pole sitter in the blue riband event of the 100m in the absence of injured Jamaican rival Usain Bolt, added: My groin is okay, it felt good. I have the 100m in Brussels but possibly it will not be the last race of the season for me. The 28-year-old Gay claimed a victory over Bolt in Stockholm earlier this month, the Jamaican world record holders first since pre-Beijing Olympics in 2008. Last weekend, Gay ran an impressive 9.78sec in miserable, damp conditions in Londons Crystal Palace. Gay has targeted beating his personal best (and second fastest time ever) of 9.69sec set in Shanghai last year in the final Diamond League meet in Brussels next week. But on the eve of this meet the triple world sprint champion from the 2007 Osaka worlds admitted that he needed a break from competition. At the end of the season, I need a vacation. Ive never taken one, he said. This will be the first time. Not sure where I am going to go, but it will be nice to just relax.
