John Isner

John Isner was born April 26th, 1985 in Greensboro, North Carolina. He achieved his career highest rank of number 55 on August 10, 2009.

Isner is known for his booming serve which is attributed, at least in part, to his 6 ft 9 in height. Commentators have also praised his composure during matches, as displayed during his five consecutive 3rd-set tiebreaker wins in Washington, which were marked by his ability to bring out huge serves when it mattered most. Additionally he is known to back up his huge serves with approaches to the net, though he does not strictly serve-and-volley.
