NEW YORK (AP) — American John Isner served 24 aces and maxed out at 144 mph to win his second-round match at the U.S. Open.
The 18th-seeded Isner, the highest ranked U.S. man left in the tournament, defeated Switzerland’s Marco Chiudinelli 6-3, 3-6, 7-6 (7), 6-4 on Friday.
Isner, who defeated Nicolas Mahut 70-68 in the fifth set of the first round at Wimbledon, has spent just under five hours on the court in his two wins at Flushing Meadows — still six hours less than he spent in the history-making win over Mahut.
He needs one more win to match his best showing ever at the U.S. Open or any Grand Slam tournament.
