John Isner was able to win his opening round match at the 2012 U.S. Open as he defeated Belgium's Xavier Malisse on Wednesday by a score of 6-3, 7-6 (5), 5-7 and 7-6 (9). The match was much close than expected for the No. 9 seeded Isner, but he used his serve to help get the win as he had 20 aces.

Isner also shined when the set was on the line as won both sets that required a tiebreaker, which were the second and fourth. In the final set Malisse tried to hang on to force a fifth and final deciding set, but on an easy backhand volley the ball fell short and hit the net which allowed Isner to get the win.

Isner's next match will be against Finland's Jarkko Nieminen.
