NEW YORK (AP) — Marathon man John Isner had 19 aces and needed less than two hours to eliminate Portugal’s Frederico Gil 6-4, 6-3, 6-4 in the first round of the U.S. Open on Wednesday night.

The 18th-seeded Isner is best known for his record-breaking 11-hour, 5-minute victory over Nicolas Mahut at Wimbledon this year, a first-round match that was spread over three days and finished 70-68 in the fifth set.

There were no such theatrics against Gil, in part because Isner did not face a single break point, although he only converted three of 19 that he earned.

Isner was playing for the first time since injuring his ankle in Cincinnati two weeks ago.
