At 6’10” with a serve that’s shot out of a cannon, John Isner is one of the most physically imposing players on tour. In 2007, mere weeks into his pro career, Isner made waves by winning five consecutive matches on third-set tiebreakers en route to making the final in Washington. He also made it to the third round of the U.S. Open in his inaugural season before losing to Roger Federer. His next victory at a major didn’t come until 2009, when he made an impressive run to the fourth round of the U.S. Open, defeating fifth-ranked Andy Roddick in the process. The most memorable moment of his career came the following year, at Wimbledon. At the All England Club, Isner triumphed over Nicolas Mahut in what became the longest match in tennis history. Isner won, 6-4, 3-6, 6-7 (7), 7-6 (3), 70-68, in the three-day, 11-hour first-round showdown. In 2012, he cracked the Top 10 for the first time after beating world No. 1 Novak Djokovic to reach the final in Indian Wells.
