NEW YORK -- Madison Keys slept until almost 11 a.m. Monday. She didnt arrive at Arthur Ashe Stadium until 6:30 p.m., knowing that a late night on the court awaited her.Keys and fellow American Alison Riske didnt envision it going quite so late. Their first-round US Open match didnt end until 1:48 a.m. Tuesday.It was the latest finish for a womens match in tournament history. Typically, the women play first and the men second in the night session, so six mens matches have ended later than this one did.The first night matches of the US Open always start later because of the opening ceremony, but more often than not, theyre routs with a top player facing an unseeded opponent. But on Monday, No. 1 Novak Djokovic was pushed to four sets, then Riske and Keys went three.The eighth-seeded Keys rallied from down a set and a break to win 4-6, 7-6 (5), 6-2 in 2 hours, 26 minutes. Both players said they werent particularly aware of how late it was.Now that Im a part of it, yay, Keys said of setting a record. Lets not try to break it.Asked whether shes a night owl, Riske said simply: No.Keys, meanwhile, is definitely not a morning person.This time of morning, I am, she said in her on-court interview shortly before 2 a.m. At 6 a.m., 7 a.m., Im not a good person.The 60th-ranked Riske had two points on her serve at 5-4 in the second-set tiebreaker to try to close out the match, but Keys won them both and clinched the set on the next point.Riske has lost 10 straight Grand Slam matches. Shes 2-16 against top-10 opponents, though one of the victories came against Petra Kvitova when Riske reached the round of 16 at the 2013 US Open.Its only a matter of time that things start turning my way, she said.Keys took a medical timeout in the second set to have a trainer work on her right shoulder. She said it was just soreness, and she didnt expect it to be an issue going forward.The 21-year-old is coming off a run to the Olympic semifinals, but she withdrew from the hard-court tuneup at New Haven because of a neck injury.Earlier Monday, French Open champ Garbine Muguruza lost the first set to Belgian qualifier Elise Mertens, called for the trainer and complained about trouble breathing. The third-seeded Spaniard, however, recovered to win the second set without dropping a game and then pulled off a tough third set to move on with a 2-6, 6-0, 6-3 win.The 22-year-old Muguruza, who had to save a break point at 3-3 in the third, said she thinks the heat played a part in her breathing problems. Temperatures were in the low 90s, and Muguruza said she had forgotten there were towels with ice available to cool off during changeovers.The 137th-ranked Mertens is 20 years old and was making her Grand Slam debut. This was the first time she faced a top-20 opponent. Muguruza has never gotten past the second round at the US Open.Olympic gold medalist Monica Puig?wasnt as fortunate as Keys and Muguruza. The 32nd-seeded Puig was upset by 61st-ranked Zheng Saisai 6-4, 6-2. Puig insisted Saturday that she was mentally ready for the years final major after the whirlwind of the past couple weeks, when she stunningly beat three Grand Slam champions to become Puerto Ricos first gold medalist and was feted with a parade on the island.Still, she recognized that it was quite possible her US Open trip wouldnt go well and reminded herself that shes just 22 years old. Shes now 1-3 at Flushing Meadows.Zheng, also 22, upset Agnieszka Radwanska at the Olympics. Shell be seeking to make it to the third round at a major for the first time.Australian Open champ Angelique Kerber?advanced to the second round without losing a game, as her opponent retired early in the second set. The second-seeded Kerber led 6-0, 1-0 after 33 minutes when Polona Hercog stopped because of dizziness and cramping. The 120th-ranked Slovenian, who won just nine points in seven games, said she had been sick for several days.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 has never been past the third round at a major, came in 2-1 against Kerber in tour-level matches, but they hadnt met since 2011.Had Hercog withdrawn before the match, a lucky loser who fell in qualifying could have replaced her. Told that Croatian player Donna Vekic had sarcastically tweeted classy about the match, Hercog said: Its not my fault she lost in the last round of qualies.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.Two-time US 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 in the first match at the new 8,000-seat Grandstand.She lost in the first round at this years Australian Open and Wimbledon and skipped the French Open because of a right ankle injury that forced her to miss more than two months. The former No. 1 players ranking has slipped to 74th, and shes unseeded at Flushing Meadows for the first time since her debut in 2007.At this point, Im just happy when Im healthy, Wozniacki said. Thats been my focus this year: to try and get back to healthy and 100 percent body-wise. Its been a struggle, but I feel like Im there now.The 20-year-old Townsend, ranked 146th, was playing in her second US Open.I could taste it, I was so close, said Townsend, who trains in the heat in Atlanta.Italys?Roberta Vinci, who stunned Williams?at last years US Open en route to the final, won the first match in the tournaments 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.In the 2015 semifinals at Flushing Meadows, Vinci -- unseeded and ranked 43rd at the time -- upset Williams to end the Americans bid for tennis first calendar-year Grand Slam in 27 years. That put Vinci into her first major final, in which she lost to another Italian, childhood friend Flavia Pennetta.The temperature hit 90 degrees Monday, but the new retractable roof atop Arthur Ashe Stadium provided some shade for spectators and, on one side of the court, players.The Associated Press contributed to this report.

ATLANTA -- Paul Johnson hears criticism of his Georgia Tech teams mixed performance in its 2-0 start, and he is reminded that it can be dangerous to reach conclusions after only two games.Last year was a painful example.The Yellow Jackets outscored their first two opponents by a combined margin of 134-19 in 2015. After the strong 2-0 start, they lost five straight and finished 3-9 overall with only one Atlantic Coast Conference win.The lesson was that it was unwise to read too much into lopsided wins over 2015 underdog opponents Alcorn State and Tulane.Georgia Tech, which plays Vanderbilt (1-1) on Saturday, opened this season with a narrow win over ACC rival Boston College before beating Mercer 35-10 last week. Apparently, Johnson has heard feedback that the win over Mercer should have been more impressive.The first two games we came out of the gate last year and killed everybody, and everybody was talking about how great we were, and we werent, Johnson said Tuesday when asked what he has learned about his team.And now after the first two games this year people want to talk about how bad we are, and were not. So its kind of somewhere in between.Johnson should learn more about his team in the next few weeks. After the visit from Vanderbilt , Georgia Tech plays No. 5 Clemson and No. 25 Miami.Johnson provided hints he is encouraged by what he has seen so far.At least this team in the first game found a way to win without our A game, he said, referring to the 17-14 win over Boston College in Dublin.Johnson said he gave a C grade to the win over Mercer.This game also should reveal much to Vanderbilt coach Derek Mason. The Commodores have lost five straight in the series and are 0-11-1 against the Yellow Jackets since 1941.ddddddddddddere facing a Georgia Tech team who we have not had the opportunity to beat in a while, Mason said Tuesday. So with that says theres an opportunity in front of us to do something great.Georgia Tech freshman running back Dedrick Mills, who scored the game-winning touchdown against Boston College, was suspended last week for a violation of team rules. He is back with the team and may start against Vanderbilt. Mills and Marcus Marshall are listed as co-starters.Mills rushed for 73 yards on 18 carries against Boston College.Marshall and Quaide Weimerskirch lost fumbles against Mercer.Qua Searcy ran for a career-high 91 yards on only seven carries in his first career start against Mercer.Quarterback Justin Thomas, who sat out the second half last week with a minor injury, should return against Vanderbilt.Matthew Jordan and TaQuon Marshall played behind Thomas. The three quarterbacks combined to run for 125 yards and four touchdowns in the spread-option offense.I thought Saturday we made some improvement in some areas, Johnson said. Weve still got a ton of work to do. Certainly were not where wed like to be in any facet.Its no surprise that the triple-option aspect of Georgia Techs offense has led to extra work for Mason and his staff. He said his staff began studying the offense this summer.---AP Sports Writer Teresa M.
