The Latest: Serena Williams edges Maria Sakkari at US Open

NEW YORK (AP) — The Latest on the U.S. Open tennis tournament (all times EDT):

2:40 p.m.

Serena Williams is into the quarterfinals at the U.S. Open for a 12th consecutive appearance.

It wasn’t easy, though.

Williams needed to come from behind in the third set before taking another step closer to Grand Slam title No. 24 by edging Maria Sakkari 6-3, 6-7 (6), 6-3 on Monday.

This was a rematch from less than two weeks ago at the Western & Southern Open. That one was won by Sakkari, also in three sets, when Williams dealt with leg cramps and faded down the stretch.

This time, Williams was two points from victory at 6-all in the tiebreaker but dropped the next two points and the set. Then she trailed 2-0 in the third before turning things around.

Williams, who turns 39 in less than three weeks, will face an unseeded opponent — either Alize Cornet or Tsvetana Pironkova — for a semifinal berth.

The American has won six of her 23 major singles championships at the U.S. Open.

Alex de Minaur has moved into his first Grand Slam quarterfinal by beating Vasek Pospisil 7-6 (6), 6-3, 6-2 at the U.S. Open.

The key to the match in Louis Armstrong Stadium on Monday was the opening-set tiebreaker. Pospisil held four set points at 6-2 but failed to convert any.

De Minaur took a half-dozen points in a row to take the set and was in control from there.

He is a 21-year-old from Australia who is seeded 21st at Flushing Meadows.

In the quarterfinals, de Minaur will face No. 2 seed Dominic Thiem or No. 15 Felix Auger-Aliassime.

Williams owns six U.S. Open titles and 23 Grand Slam singles championships in all.

Sakkari, a 25-year-old from Greece, is trying to reach her first Grand Slam quarterfinal.

The winner will face Alize Cornet or Tsvetana Pironkova next.
