Sam Querrey of the USA won the biggest title of his career to date last week when he brought home the ATP 500 event in Memphis, beating fellow American and doubles partner John Isner in the final. Querrey also managed to beat Wimbledon finalist and compatriot Andy Roddick in the Quarter Finals, it was Querrey’s 2nd win against Roddick, having beaten him in Cincinnati, Ohio last year. Sam Querrey is tipped by many experts to become America’s next number 1 player once Andy Roddick does finally retire. In the US Open 4th round in 2008 Querrey also managed to take the then World Number 1 Rafael Nadal to 4 sets. Perhaps even more impressively, later that year Querrey also managed to take a set off Nadal in the David Cup final which was played at Madrid on Clay. Next week Sam Querrey and Isner will lead the USA in the 1st round of their 2010 Davis Cup campaign in Serbia.
