ATLANTA -- Top-seeded John Isner overpowered Dudi Sela on Sunday to successfully defend his Atlanta Open title, blowing serve after serve past the 1.75-meter Israeli player in a 6-3, 6-4 victory.
Serving for the match, the 2.08-meter Isner fell behind 30-0 before Sela sent a backhand into the net, and then watched almost helplessly as the American ripped three straight aces for the win. Isner finished with 15 aces to Sela's two.
Ranked 12th, Isner has won two of his nine career titles in Atlanta, where he also lost to Mardy Fish in the 2010 and 2011 finals and to eventual champion Andy Roddick in the 2012 semifinals.
In running his Atlanta record to 16-3, the former University of Georgia star had the crowd on his side on a hot afternoon under bright sun.
Isner served beyond 225 kph on several occasions, while Sela was in the 185 kph range. Isner also crushed Sela's second serves, which often travelled at around 130 mph, to win 61 per cent of Sela's second serves.
Sela was playing in just his second ATP final after losing to Roddick in Beijing in 2008.
Isner earned $103,100, and Sela made $54,300.
American Jack Sock and Canadian Vasek Pospisil won the doubles title. Sock and Pospisil, the Wimbledon doubles winners three weeks ago in their first tournament together, beat Americans Steve Johnson and Sam Querrey 6-3, 5-7, 10-5.
