Isner downs Harrison at Atlanta

John Isner claimed his fourth ATP Atlanta title, saving a set-point in both sets en route to a 7-6 (8/6), 7-6 (9/7) win over Ryan Harrison.

Second-seeded American Isner notched his second ATP title in as many weeks after lifting the trophy in Newport last week.

Atlanta was the perfect place for him to keep the momentum going. Isner, who has reached the final in seven of eight editions of the tournament, added a fourth title to those he won in 2013, 2014 and 2015.

Harrison, seeded fourth, was denied a second career ATP title, to go with his victory in Memphis in February. "There wasn't much that separated us at all," Isner said yesterday. "So I'm happy to win that match in straight sets ... very happy to win."

Both players held serve throughout the opening set to force the tiebreaker, in which Isner faced a setpoint at 5-6 but saved it with a booming serve.

He then converted a setpoint of his own at 7-6 with a forehand winner.

Harrison ended Isner's run of 75 straight service holds -- dating back to last week's Newport tournament -- when he broke for a 2-0 lead in the second set. But Isner broke back immediately, and they held serve to another tiebreaker. Harrison made Isner work for it, saving a match point with a forehand winner before giving himself a setpoint at 7 -6. "We've both got that competitive side where we want to dig in and win," Harrison said later.
