America's number 1 Andy Roddick will take on compatriot Sam Querrey in the Quarter Finals in the ATP Event in Memphis later today.
Roddick is the defending champion in Memphis and he will be looking to go deep in the tournament once again this year but he is likely to be sternly tested by the young Californian.
Querrey beat Roddick in the 3rd round of the Masters 1000 event in Cincinnati last year 7-6 7-6.
Roddick however won their last match in the last 8 in San Jose last week, 2-6 7-6 7-6. Roddick went on to reach the final in San Jose before being beaten in 3 sets by the Spaniard Fernando Verdasco.
Roddick also won his 1st tournament of the year in Brisbane in January when he defeated Radek Stepanek 7-6 7-6.
However the American was beaten in the last 8 of the Australian Open by Marin Cilic of Croatia in 5 sets.
