MELBOURNE, Australia (AP) — Grand Slam tournament winners Naomi Osaka and Serena Williams withdrew from their tuneup tournaments, their focus already on the Australian Open, well before Alexander Zverev tweaked his back in the second set of his must-win ATP Cup match against Daniil Medvedev.

He left the court for treatment Saturday and returned, taking the match to three sets before Medvedev finally converted to secure Russia's win over Germany and a spot in the final.

No. 4-ranked Medvedev lifted when Zverev started to struggle but he got tight in the end, twice double-faulting on match point before serving out for 3-6, 6-3, 7-5. Andrey Rublev had earlier beaten Jan-Lennard Struff 3-6, 6-1, 6-2.

“Crazy match,” Medvedev said. “Happy to win even if many things I didn’t like.

"Most important thing is to win for the country and be in the final.”

Russia will meet Italy in the final after Fabio Fognini beat Pablo Carreno 6-2, 1-6, 6-4 and Matteo Berrettini swept Roberto Bautista 6-3, 7-5 to account for 2020 runner-up Spain. Rafael Nadal didn't play for Spain during the week because of lower back soreness but did practice and is expected to be OK for the Australian Open, where he's aiming for a men's record 21st Grand Slam title.

Zverev had helped Germany to a 2-1 quarterfinal win over defending champion Serbia, rebounding from a narrow loss to top-ranked Novak Djokovic in the singles with a victory in the deciding doubles.

But in the semis, his movement and serve slowed after getting a medical timeout for treatment in the second set.

Medvedev rallied and set up victory with a service break in penultimate game, and Zverev shattered a racket in frustration.

“It helped me he started moving slower, serving slower in the second set,” Medvedev said. “I felt like in the beginning of the third, I could stay in front and get the match done easy. But in the heat of the match, he started feeling better. I had to stay in it as much as I could.”

OTHER ATP FINAL Felix Auger-Aliassime and Daniel Evans will both be aiming to win their first titles on the elite men's tour when they meet in the Murray River Open final.

Third-seeded Auger-Aliassime had a 6-1, 6-2 win over Corentin Moutet and eight-seeded had a 6-2, 6-2 win over Jeremy Chardy.


A day after beating 2020 champion Sofia Kenin in a rematch of last year's Australian Open final, Garbine Muguruza beat eighth-seeded Marketa Vondrousova 6-1, 6-0 to set up a final against top-ranked Ash Barty at the Yarra River Classic.

“Very happy for sure — it’s another final,” Muguruza said. “I played well today. My serve was working in the right moments.”

She knows she'll have to step it up against Australian star Barty, who will have the crowd — however small it may be during the COVID-19 pandemic — on her side.

“Very exciting. Always good to play the top players,” Muguruza said. “We’ve had some tough matches. I’m expecting another battle.”

Barty had the day off after Serena Williams withdrew Friday night from their match, citing a sore shoulder.

Williams attended a news conference instead on Saturday, and said she was feeling good for her shot at a record 24th Grand Slam title.

“I’ve gotten a lot of treatment already on my shoulder but I’m super confident it’s going to be great,” Williams said. “It’s definitely something that I’m going to have to deal with, and knowing that going into the tournament definitely helped."


No. 3-ranked Osaka pulled out of her Gippsland Trophy semifinal against Elise Mertens because of shoulder soreness.

Osaka won the U.S. Open in 2018 and last year and claimed the Australian title in between, in 2019. She said she's had a “slight shoulder thing since like 2018” and needed to rest ahead of the Grand Slam. Mertens got a walkover into a final against Kaia Kanepi, who had a 6-3, 7-6 (6) semifinal win over Ekaterina Alexandrova.

“It kind of flared up again because I played, like, a lot of matches back-to-back," Osaka said. “For me, my main focus is hoping I can rest enough before the Open.”

Organizers put on six tournaments this week to give all players who flew into Australia and had to quarantine for 14 days some high-level matches to prepare.

A 24-hour suspension during the week — when 507 people, including 160 players, had to go back into isolation and get tested because a hotel quarantine worker was infected with the coronavirus — meant the semifinals and finals were crammed into the last weekend.

“I would say it is a factor because, for me, I don’t normally play the tournament right before a Slam,” Osaka said. "But I felt like it was really necessary to get matches in. I think everyone felt that way.

“I’m kind of sad that I wasn’t able to play today. But I thinkin the end it’s the right decision.”


After the four semifinalists were determined, the WTA announced “Sunday’s two semifinal showdowns will be the last matches of the Grampians Trophy. Due to the delayed schedule, the final will not be played.”

There were no immediate details regarding points or prize money.

Fifth-seeded Maria Sakkari beat three-time major winner Angelique Kerber 6-4, 6-2 to reach the Grampians Trophy semifinals against No. 6 Anett Kontaveit, who got a walkover in the quarterfinals when two-time Australian Open winner Azarenka withdrew because of a lower back problem.

Seventh-seeded Jennifer Brady beat Barbora Krejcikova and will next play 20-year-old Anna Li, who qualified for her first semifinal on the WTA Tour with a 6-3, 6-1 win over Sorana Cirstea.

The tournament created for players who had to go into hard lockdown during the quarantine because they shared a charter flight to Australia with somebody who later tested positive for COVID-19.

The Grampians Trophy started Wednesday but lost time when all matches at Melbourne Park were suspended for 24 hours.
