The Latest: Tsonga beats Anderson, into US Open 4th round
NEW YORK (AP) The Latest on the U.S. Open (all times local):
Ninth-seeded Jo-Wilfried Tsonga is the first men's player into the round of 16 at this year's U.S. Open.
Tsonga beat 23rd-seeded Kevin Anderson - a surprise quarterfinalist in 2015 - 6-3, 6-4, 7-6 (4) on Friday. Each player had 13 aces, but Tsonga managed to break Anderson's serve twice while saving all seven break points he faced.
Anderson upset Andy Murray in the fourth round last year at Flushing Meadows, but he's struggled with injuries this season.
The U.S. Open is the only major at which Tsonga has not reached the semifinals. He was the 2008 Australian Open runner-up.
Roberta Vinci, last year's U.S. Open runner-up, didn't drop a game in the first set, failed to serve out the match in the second, then hung on in the third to keep another run at Flushing Meadows going.
The seventh-seeded Italian needed nearly two hours to top 102nd-ranked Carina Witthoeft 6-0, 5-7, 6-3 in the third round Friday. This is the fourth time Vinci has reached the round of 16 at the U.S. Open - she's done it just three times combined at the other majors.
And last year, she stunned Serena Williams in the semis to thwart her Grand Slam bid. It was Vinci's first major final at age 32.
The 21-year-old Witthoeft, who's been ranked as high as 49th, was looking to make her first Grand Slam round of 16. She's now 0-5 against top-10 opponents.
Vinci was two points from victory while serving at 5-4 in the second set, but Witthoeft broke back, part of a run of four straight games to even the match. Vinci went up a break to start the third only for Witthoeft to later get the set back on serve. Then Vinci won the last three games to move on.
Two-time U.S. Open runner-up Caroline Wozniacki has reached her first Grand Slam round of 16 since 2015 Wimbledon.
Her ranking down to No. 74 after an ankle injury and on-court struggles, Wozniacki beat Monica Niculescu 6-3, 6-1 on Friday. It's the first time since January she's won three matches at the same tournament.
Against the 58th-ranked Niculescu, who presents an unusual style with a forehand slice, Wozniacki played more aggressively than her normal defensive game. Wozniacki is now 7-0 against the Romanian, who was trying to equal her best performance at a major by reaching the round of 16.
Anastasija Sevastova has followed up her upset of Garbine Muguruza by equaling her best performance at a Grand Slam.
About 38 hours after she stunned the French Open champ, the 48th-ranked Sevastova swept past No. 59 Kateryna Bondarenko 6-4, 6-1 on Friday to reach the round of 16 at the U.S. Open. The Latvian also made it that far at the 2011 Australian Open, but in May 2013, she retired after a series of injuries.
Sevastova returned to tennis at the start of last season, and at this year's Australian Open, she played her first major since 2011. She reached the second round at Melbourne and Roland Garros then lost her first match at Wimbledon as she steadily climbed back up the rankings.
Bondarenko was a U.S. Open quarterfinalist in 2009 but hasn't been past the third round at a Grand Slam since.
Three past champions are on the U.S. Open lineup Friday, with Novak Djokovic, Rafael Nadal and Marin Cilic all seeking to move on to the round of 16.
The No. 1-ranked Djokovic, who experienced problems with his right arm in the first round and didn't have to play in the second when his opponent withdrew with an injury, takes on 61st-ranked Mikhail Youzhny in Arthur Ashe Stadium.
No. 4-seeded Nadal faces Youzhny's doubles partner, Andrey Kuznetsov, on Ashe at night, while No. 7 Cilic plays No. 26 Jack Sock of the United States in Louis Armstrong Stadium.
On the women's side in Ashe, second-seeded Angelique Kerber, the Australian Open champ, faces 17-year-old American qualifier CiCi Bellis. And former No. 1 Caroline Wozniacki - down to No. 74 in the rankings thanks to injury issues and early exits at tournaments - takes on No. 58 Monica Niculescu.
Weather should not be a factor, with sunny skies and temperatures in the high 70s and low 80s.
