The Latest: Wawrinka beats Medvedev, into Aussie Open QFs
MELBOURNE, Australia (AP) — The Latest on the Australian Open (all times local):
Stan Wawrinka has advanced to the Australian Open quarterfinals with a five-set victory over fourth-seeded Daniil Medvedev.
The 2014 Australian Open champion dominated the fourth-set tiebreaker and then broke Medvedev in the opening game of the deciding set. He won 6-2, 2-6, 4-6, 7-6 (2), 6-2.
Medvedev's only other loss so far in 2020 was to Novak Djokovic in the ATP Cup. Wawrinka will play either Alexander Zverev or Andrey Rublev in the quarterfinals.
Medvedev was given an unsportsmanlike conduct warning in the final set when he became upset with the umpire when he wasn't allowed to challenge a call.
It was his 300th tour-level win on hard courts.
Bob and Mike Bryan have lost their third-round doubles match in their last trip to the Australian Open.
The U.S. twins, six-time champions in Australia, lost 6-3, 6-4 to fourth-seeded Ivan Dodig and Filip Polasek.
The 41-year-old Bryans, who first played at Melbourne Park in 2000, are planning to retire at the end of this year. This was their 85th Grand Slam tournament as a team. They have combined for 16 Grand Slam doubles titles and reached 30 finals at the majors, and are the most successful doubles combination of all time.
Two-time Grand Slam champion Garbiñe Muguruza has moved into the quarterfinals of the Australian Open with a 6-3, 6-3 win over ninth-seeded Kiki Bertens.
Muguruza won the 2016 French Open and 2017 Wimbledon. She is unseeded at a Grand Slam tournament for the first time since the 2014 French Open, when she was ranked 35th and also made the quarterfinals.
She came into the Australian Open after withdrawing from her quarterfinal match at the Hobart International due to a virus. But Muguruza says she is feeling better each day.
Muguruza will next play the winner of a later fourth-round match between Angelique Kerber and Anastasia Pavlyuchenkova.
Anett Kontaveit rallied from a set and a break down to beat 18-year-old Iga Swiatek 6-7 (4), 7-5, 7-5 and reach the quarterfinals of a major for the first time.
Kontaveit twice served for the match in the third set but finally clinched it when she broke Swiatek's serve.
The 28th-seeded Kontaveit will next play Wimbledon champion Simona Halep, who advanced over Elise Mertens in straight sets.
Two-time French Open runner-up Dominic Thiem has beaten Gael Monfils 6-2, 6-4, 6-4 to book a quarterfinal spot at the Australian Open for the first time.
It was Thiem's sixth consecutive victory over the French player, and made him the first player from Austria to make it to the quarterfinals at Melbourne Park since Stefan Koubek in 2002.
Thiem will play either top-ranked Rafael Nadal or Nick Kyrgios in the quarterfinals on Wednesday. Thiem has lost the last two French Open finals to Nadal and is 4-13 in their career meetings.
Wimbledon champion Simona Halep has reached the quarterfinals at the Australian Open with a straight-sets win over Elise Mertens.
Halep appeared to be cruising after winning the first set and going up a service break in the second, but Mertens broke back to level the second set at 4-4. Halep responded by converting her fifth break-point chance in the next game and served out at love to clinch the match. Halep will next play either Anett Kontaveit or Iga Swiatek.
No. 4-seeded Halep reached the Australian Open final in 2018 and won her first major title at the French Open that year.
