The Latest: Wozniacki wins first Grand Slam match of 2016
NEW YORK (AP) The Latest on the U.S. Open (all times local):
2:05 p.m.
Two-time U.S. Open runner-up Caroline Wozniacki rallied from a set down for her first Grand Slam match win of 2016.
Wozniacki beat American qualifier Taylor Townsend 4-6, 6-3, 6-4 on Monday in the first-ever match at the new 8,000-seat Grandstand. She lost in the first round at this year's Australian Open and Wimbledon and skipped the French Open because of a right ankle injury that forced her to miss 2+ months. The former No. 1 player's ranking has slipped to 74th, and she's unseeded at Flushing Meadows for the first time since her debut in 2007.
The 20-year-old Townsend, ranked 146th, was playing her second U.S. Open.

Australian Open champ Angelique Kerber advanced to the second round at the U.S. Open when her opponent retired early in the second set without winning a game.
The second-seeded Kerber led 6-0, 1-0 after 33 minutes when Polona Hercog stopped. The 120th-ranked Slovenian won just nine points in seven games.
After the first set on a 90-degree day, Hercog took a medical timeout. Trainers checked her blood pressure and rubbed ice bags on her legs.
Hercog, who's never been past the third round at a major, came in 2-1 against Kerber in tour-level matches, though they hadn't met since 2011.
Kerber, who lost to Serena Williams in the Wimbledon final, has a chance to overtake her for the No. 1 ranking depending on their results at Flushing Meadows.

Richard Gasquet, the first seeded player to lose at the U.S. Open, summed up his quick exit this way: ''Not sure I could do worse.''
The 13th-seeded Gasquet, a semifinalist at Flushing Meadows in 2013, hadn't lost in the first round at a Grand Slam tournament since the French Open 6+ years ago.
His 6-2, 6-2, 6-3 loss Monday was the first career victory over a player ranked in the top 15 for No. 84 Kyle Edmund of Britain.

1:25 p.m.
Marin Cilic, the 2014 U.S. Open champ, is through to the second round with a straight-set win.
The seventh-seeded Cilic beat 108th-ranked Rogerio Dutra Silva 6-4, 7-5, 6-1 on Monday despite posting more unforced errors than winners (24-23). Cilic is coming off his first Masters title, beating Andy Murray in the final at Cincinnati.
Dutra Silva is now 0-3 against top-10 players. He came in 3-3 in his career at the U.S. Open and 0-5 in the other majors.

In his U.S. Open debut, Kyle Edmund has upset 13th-seeded Richard Gasquet.
The 21-year-old Brit won 6-2, 6-2, 6-3 on Monday against the 2013 U.S. Open semifinalist. Edmund, ranked 84th, had 40 winners, 21 on his forehand. He has twice made it to the second round at the French Open.
Gasquet hadn't lost in the first round at a major since 2010 at Roland Garros.

The woman who stunned Serena Williams at last year's U.S. Open en route to the final, Roberta Vinci of Italy, won the first match in the tournament's refurbished Arthur Ashe Stadium.
Vinci, who is seeded No. 7, overcame some second-set jitters to beat 46th-ranked Anna-Lena Friedsam of Germany 6-2, 6-4 on Monday.
In the 2015 semifinals at Flushing Meadows, Vinci - unseeded and ranked 43rd at the time - upset Williams, ending the American's bid for tennis' first calendar-year Grand Slam in 27 years. That put Vinci into her first major final, where she lost to another Italian, childhood friend Flavia Pennetta.
The temperature hit 90 degrees Monday, but the new retractable roof atop Ashe provided some shade for spectators - and, on one side of the court, players.

Play has started at the 2016 U.S. Open under sunny skies with no rain in the forecast for days, which could delay the first official use of the new retractable roof on Arthur Ashe Stadium.
The $150 million roof, which can close in about seven minutes, is to be used, according to tournament officials, only ''in the event of inclement weather or the strong possibility of inclement weather.''
Neither is expected in the next few days, with forecasts calling for clear skies and highs in the 80s.
The roof is still set to make its debut, of sorts, at Monday night's opening ceremony. The U.S. Tennis Association plans to shut the roof after the day session and open it for effect while Phil Collins performs ''In the Air Tonight.''
