Roddick keeps retirement at bay

Andy Roddick set up a blockbuster fourth-round clash against Juan Martin Del Potro at the US Open as he kept the fat lady at bay for at least a couple more days.

The American’s announcement on Thursday that this would be his last tournament has put a completely different spin on his matches and he was roared on by the Arthur Ashe crowd on Sunday as he defeated Italy’s Fabio Fognini 7-5 7-6 (7/1) 4-6 6-4.
