Quarterfinal Tuesday at Australian Open: Venus opens play

MELBOURNE, Australia (AP) It's quarterfinal Tuesday for half of the men's and women's draws at the Australian Open, with Venus Williams and Roger Federer among those looking to advance to the final four of the year's first Grand Slam tournament.

Williams begins play on Rod Laver Arena against Anastasia Pavlyuchenkova, and another American, CoCo Vandeweghe, follows against 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.

Federer, back in action after a six-month injury layoff, plays Mischa Zverev to open the night session at Rod Laver, when Laver himself will be in the building. Zverev's previous match was a fourth-round upset victory over top-seeded Andy Murray.
