NEW YORK — Marathon man John Isner hit 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.
The 6-foot-9 Isner was playing for the first time since injuring his ankle in Cincinnati two weeks ago, and he said it "felt great."
Never miss a local story.
Meanwhile, 18-year-old American qualifier Ryan Harrison upset 15th-seeded Ivan Ljubicic, 6-3, 6-7 (4), 6-3, 6-4. Unseeded Michael Llodra upset Wimbledon runner-up Tomas Berdych, 7-6 (3), 6-4, 6-4.
Winners included No. 4-seeded Andy Murray, the 2008 runner-up, who said he wore a hat during a match for the first time in four or five years because of the oppressive New York heat; No. 12 Mikhail Youzhny; No. 14 Nicolas Almagro; and No. 20 Sam Querrey, who beat NCAA singles champion Bradley Klahn of Stanford 6-3, 4-6, 7-5, 6-4 in an all-American matchup.
At night, defending champion Kim Clijsters reached the third round by beating 201st-ranked qualifier Sally Peers of Australia 6-2, 6-1. They were followed onto the court at Arthur Ashe Stadium by 2003 U.S. Open champion Andy Roddick, who took on Janko Tipsarevic in a second-round match.
Harrison, who is based in Bradenton, Fla., is the first U.S. male teen to beat a top-20 opponent at any Grand Slam tournament since a 19-year-old Roddick knocked off No. 11 Alex Corretja at the 2001 U.S. Open.
You don't have to go nearly as far back to find a female teen from the United States who pulled off that sort of upset, of course: Melanie Oudin of Marietta, Ga., was 17 a year ago when she reached the U.S. Open quarterfinals by beating two top-20 players.
Oudin's 2010 stay in New York was shorter: She lost in the second round to No. 29 Alona Bondarenko 6-2, 7-5.
"Definitely disappointing," Oudin said. "I still have, hopefully, like, 10 more years in my career, hopefully 10 more U.S. Opens ahead of me."
