On his 30th birthday, Andy Roddick announced that this year's U.S. Open will be his final tournament. Roddick won the U.S. Open in 2003 and after playing Davis Cup for years, helped the U.S. team win the championship in 2007. The only active players who have won more titles than Roddick are Roger Federer (76) and Rafael Nadal (50). The tennis world reacted to the news on Twitter.

Fan reaction

Grew up watching Roddick perform at a high level. Too bad it came at the same time as Federer and Nadal. Going to be tough to watch tennis without you Andy!!

He seems too young to retire.
