The Latest: Player caught using cellphone during Open match
NEW YORK (AP) The Latest on the U.S. Open (all times local):
4 p.m.
Marcos Baghdatis was warned by a chair umpire for using his cellphone during a changeover while losing his U.S. Open fourth-round match against Gael Monfils.
Baghdatis, the runner-up at the 2006 Australian Open, sat in his sideline chair after falling behind 4-1 in the second set and fiddled with his phone, holding it near a white towel that was on his lap.
Using a phone during a professional tennis match is not allowed, and chair umpire Alison Hughes noticed what was going on.
Later, Baghdatis told reporters he was messaging his wife.

Caroline Wozniacki eliminated eighth-seeded American Madison Keys 6-3, 6-4 Sunday to reach the U.S. Open quarterfinals, her deepest run at a Grand Slam tournament in two years.
Wozniacki is a two-time runner-up at Flushing Meadows, but she is unseeded and ranked only 74th after a season filled with injuries and poor results. She hadn't won a match at a major in 2016 until arriving in New York.
She lost U.S. Open finals in 2009 against Kim Clijsters and 2014 against Serena Williams.
On Sunday, Wozniacki made only seven unforced errors, 26 fewer than Keys.

Gael Monfils' sizzling summer rolls on with a quarterfinal run at the U.S. Open.
The 10th-seeded Frenchman swept Marcos Baghdatis 6-3, 6-2, 6-3 on Sunday to improve to 18-2 in matches he's played since a first-round loss at Wimbledon. That stretch includes the highest-level tournament title of his career at Washington.
Three days after his 30th birthday, there were still classic Monfils moments in this one, including an attempt to tie his shoe in the middle of a point. But he has yet to drop at set at this U.S. Open.
The 31-year-old Baghdatis hadn't reached a Grand Slam round of 16 since the 2009 Australian Open.

Anastasija Sevastova, who retired from tennis for nearly two years, has reached her first major quarterfinal.
Sevastova upset 13th-seeded Johanna Konta 6-4, 7-5 on Sunday to become the first Latvian woman to make the final eight at a Grand Slam since Larisa Savchenko in 1994.
Still just 26 years old, Sevastova retired in 2013 because of a series of injuries that had made tennis no fun anymore. But she returned to the sport at the start of last season, and her ranking has steadily climbed to 48th.
Her previous best run at a major was a round of 16 appearance at the 2011 Australian Open.
As in her second-round upset of third-seeded Garbine Muguruza, Sevastova struggled to serve out the match. And as in that victory over the French Open champ, she finally closed out the win with a service break.
Sevastova broke Konta seven times in 11 service games.
Konta, an Australian Open semifinalist, collapsed to the court with trouble breathing during her second-round match, but she didn't appear to have any physical problems Sunday.

Roberta Vinci, last year's U.S. Open runner-up, is back in the quarterfinals.
The seventh-seeded Italian beat 99th-ranked Lesia Tsurenko 7-6 (5), 6-2 on Sunday. Vinci has never reached the quarters at any of the other three Grand Slams, but she's now done it four times at Flushing Meadows.
She made her first major final here last year at age 32, stunning Serena Williams in the semis to thwart the American's Grand Slam bid.
Vinci has been bothered by an injured left Achilles tendon and struggled physically at times Sunday. Exhausted after the match, she had tears in her eyes.
The 27-year-old Tsurenko had never been past the third round at a major before this tournament.
