MELBOURNE, Australia (AP) — The Latest on Tuesday from the Australian Open (all times local):

2:55 p.m.

Coco Vandeweghe beat French Open champion Garbine Muguruza 6-4, 6-0 to set up an all-American semifinal at the Australian Open.

Vandeweghe, who beat top-seeded and 2016 champion Angelique Kerber in the fourth round, will play 36-year-old Venus Williams in the semifinal. Williams is the oldest women to play a semifinal here in the Open era.

Serving for the first set, Vandeweghe faced her first break point of the set, but saved it with an ace. She clinched the 56-minute set when Muguruza, who faced nine break points in the first set, fired a backhand long.

Vandeweghe overwhelmed a listless Muguruza in the 28-minute second set when the Spanish player won only four points on her serve.

The oldest woman in the singles draw at the Australian Open is through to the semifinals: 36-year-old Venus Williams beat Anastasia Pavlyuchenkova 6-4, 7-6 (3) at Rod Laver Arena on Tuesday.

She is the oldest woman to advance this far at the Australian Open during the Open era.

Williams was behind a service break in the opening set but broke the Russian's serve twice in three games, including when Pavlyuchenkova was serving to stay in the set. Williams had three set points and clinched the set on a backhand service return.

Pavlyuchenkova double-faulted twice during the tiebreaker — including on match point — among nine during the match as Williams won six consecutive points after trailing 3-1.

Williams will play the winner of Tuesday's later match between American CoCo Vandeweghe and French Open champion Garbine Muguruza.

The last match of the afternoon session will see U.S. Open champion and 2014 Australian Open winner Stan Wawrinka take on Jo-Wilfried Tsonga.
