Australian Open:

Venus advances to semifinals.

Melbourne, Australia — Age appears to be no barrier for Venus Williams.

The 36-year-old Williams beat No. 24-seeded Anastasia Pavlyuchenkova, 6-4, 7-6 (3), on Tuesday, becoming the oldest player to reach the Australian Open women’s semifinals in the Open era.

Her 50th career win at Melbourne Park earned her a spot in the last four for the first time in 14 years.

“It’s wonderful to start the year out with this appearance,” said Williams, who hadn’t reached the semifinals here since 2003, the year she lost the final to her sister, Serena. “I want to go further. I’m not happy just with this. But I’m so happy to be in the position to like go further.”

She will next play either French Open champion Garbine Muguruza or CoCo Vandeweghe, who are both in the Australian Open quarterfinals for the first time.

Williams dropped four service games against Pavlyuchenkova, but she responded each time by breaking back. In the tiebreaker, she trailed, 3-1, before winning the last six points — clinching the match on Pavlyuchenkova’s double-fault.

The seven-time major winner has advanced through the tournament without dropping a set, recovering from a right elbow injury.

Now she is into semifinals for the second time in three majors — after a sixyear absence from the last four — and for the 21st time overall.

With her run to the Wimbledon semifinals last year, Williams became the oldest woman since Martina Navratilova in 1994 to advance so far at a major. Navratilova was 37 years, 258 days at the end of Wimbledon that year.

The record belongs to Billie Jean King, who was 39 years, 223 days when she reached the Wimbledon semifinals in 1983.

Rafael Nadal defeated Gael Monfils, 6-3, 6-3, 4-6, 6-4, in a fourth-round match on Monday, advancing to his 30th Grand Slam quarterfinal.

After a match in which Nadal had difficulty converting break points — six of 17 — the Spanish lefthander clinched it on his second match point with Monfils serving.

Nadal will next play third-seeded Milos Raonic, who is the highestranked men’s seed remaining.
