DES MOINES - Tyson Gay flew to the year’s fastest 200m of 19.74 seconds at the US athletics championships on Sunday to set himself up for a World Championship sprint double challenge. Gay, who notched the season’s fastest 100m on Friday with a victory in 9.75, again demonstrated he is fit and ready to take on six-time Olympic champion Usain Bolt and his fellow Jamaican sprinters at the World Championships in Moscow on August 10-18. Gay refused, however, to be drawn into any predictions as to how the US sprinters would stack up when the world’s best gather. “I am going to do the best I can,” Gay said. “I can’t speak for the other guys but I am going to go out there and give it my best. I wish my 100 was a little bit better. I have enough time to work on that,” he said.–AFP
