NEW YORK (AP) — The latest news on the U.S. Open tennis tournament (all times local):

5:50 p.m.

Coco Gauff cruised through her match against fellow American Madison Keys, winning 6-2, 6-3 to reach the fourth round.

The No.12 seed was smashed to open the game but fought back against the 2017 US Open runner-up in a lengthy second game en route to a 4-1 lead and was never really threatened.

The 18-year-old qualified to face China’s Zhang Shuai.

Martina Navratilova saw a clip of Serena Williams training ahead of her second match and noticed her movement seemed to have improved.

The Hall of Famer immediately had a thought.

“I was like, ‘Ooh, Serena is back,'” Navratilova said. “So yeah, I think the sky’s the limit for her now. I wouldn’t put that above her to win the whole thing.

Williams plays her third-round match on Friday night against Ajla Tomljanovic.

Footwork is one of the areas that Navratilova says can be improved with Sense Arena’s virtual reality tennis training program which will launch next month. It allows players to perform drills such as return of serve and volley, while swinging a racquet that feels similar to the real thing, without the risk of injury when hitting balls repeatedly or running on hard courts. .

Sense Arena has a hockey program used by five NHL teams and nine NCAA Division teams. CEO Bob Tetiva said mastering the swing technology used in hockey made the addition of tennis natural. The company, based in the Czech Republic, has added Navratilova to its tennis advisory board.

The 59-time Grand Slam champion says she ‘breathed’ with her first swings but quickly improved and saw the benefits of being able to train indoors or with an injury that limits the ability to run.

“Tennis is a sport that takes a long time to not be horrible, so there really are no shortcuts,” she said, “but this stuff is really a little shortcut.”

Matteo Berrettini ended Andy Murray’s attempt to come back in the fourth round of a major, beating the three-time Grand Slam champion 6-4, 6-4, 6-7(1), 6-3.

Murray, who won his first major at the US Open in 2012, has failed to reach the round of 16 at any of the four biggest tennis tournaments since Wimbledon in 2017, when he was ranked No.1. He then had to undergo two hip surgeries which led to absences from the tour.

Berrettini, the No. 13 seed who was a US Open semi-finalist in 2019, will face Alejandro Davidovich Fokina on Sunday.

Ons Jabeur has ensured that there will be at least one woman in the top five in the fourth round.

The No. 5 seed rallied to beat No. 31 Shelby Rogers 4-6, 6-4, 6-3, avoiding the type of upset that filled the first week of play at the US Open.

This is the first trip to the Round of 16 at Flushing Meadows for the Wimbledon runner-up, who has lost in the third round each of the past three years.

Top-ranked Iga Swiatek is the only other top-five player to drop out of the second round. Serena Williams ousted No. 2 Anett Kontaveit, and No. 3 Maria Sakkari and No. 4 Paula Badosa also lost their second match.

Swiatek plays his third round match on Saturday.

Andy Murray leads the game at Arthur Ashe Stadium on day five of the US Open, trying to reach the fourth round of a Grand Slam for the first time in five years.

Serena Williams also has her sights set on a place in the last 16 when she continues what could be her final tournament on Friday night against Ajla Tomljanovic.

Murray was set to face No.13 Matteo Berrettini, with victory sending the three-time Grand Slam champion to the fourth round for the first time since 2017 Wimbledon. The 2012 US Open winner will have to make do with a former Grand Slam finalist in Berrettini, who also reached the semi-finals at Flushing Meadows in 2019.

Americans Coco Gauff and Madison Keys were to follow them with a third-round match.

Top-ranked Daniil Medvedev plays the night against Wu Yibing, who is trying to become the first Chinese to reach the fourth round of a Grand Slam event since Kho Sin-Khie at Wimbledon in 1938.
