MELBOURNE, Australia (AP) — A quick look at the Australian Open:
LOOKAHEAD TO SUNDAY
Roger Federer faces one of the game's brightest new stars when he takes on Stefanos Tsitsipas in the fourth round at Melbourne Park. The 19-year-old Tsitsipas is likely to have several hundred Greek fans at Rod Laver Arena if it's anything like his first few matches. The two played against each other at the Hopman Cup team exhibition event two weeks ago but Federer acknowledges Sunday's match is "best of five, it being a fourth round of a Slam, you know, where we know now how we feel on this court." Federer has played 100 matches at Rod Laver, this will be Tsitsipas' first. Tsitsipas loves the Greek crowd support — "they give a nice atmosphere, energy on the court. I appreciate what they do. They really want it as bad as me." Rafael Nadal plays Tomas Berdych and American Frances Tiafoe plays Grigor Dimitrov in other fourth-round matches. On the women's side, home favorite Ashleigh Barty plays Maria Sharapova. Barty pulled out of doubles on Friday with a mild strain in an effort to concentrate on singles (Barty won the U.S. Open doubles title with CoCo Vandeweghe last year). Petra Kvitova plays American teenager Amanda Anisimova, 2017 U.S. Open champion Sloane Stephens takes on Anastasia Pavlyuchenkova and 2016 Australian titlist Angelique Kerber plays American Danielle Collins.
