Melbourne, Australia's second-largest city, will relax its third lockdown restrictions after authorities contained the spread of a COVID-19 cluster centered on hotel quarantine. (Erik Anderson/AAP Image via AP)MELBOURNE – Melbourne, Australia’s second largest city, will relax its third lockdown on Wednesday and allow spectators to return to the Australian Open tennis tournament after a five-day absence. Up to 30,000 tennis fans a day had been allowed into three zones in the tournament venue, Melbourne Park, before the statewide Victoria lockdown. Melbourne emerged from a 111-day lockdown in October following a fresh wave of infections that peaked at 725 cases a day. At the time, the rest of Australia was relaxing restrictions due to low case numbers after an initial nationwide lockdown.

(AP Photo/Hamish Blair)MELBOURNE – Serena Williams was not pleased with the way her play suddenly was slipping in the Australian Open quarterfinals. That was her most recent Grand Slam title. 24 on Saturday, she could end up needing to have beaten each of the top three players in the rankings: Halep, Osaka and, perhaps in the final, No. At 35, Hsieh used her tricky, two-handed shots off both sides to become the oldest woman in the professional era to make her Grand Slam quarterfinal debut.

(AP Photo/Hamish Blair)MELBOURNE – Serena Williams tumbled to the ground, her heavily taped right ankle turning, her body contorting, her racket flying. Grabbing the last two games, Williams pulled out 6-4, 2-6, 6-4 victory over No. Oh, my goodness.”Sabalenka — a 22-year-old from Belarus playing in only her second fourth-round Slam match — was visibly and audibly frustrated. Dominic Thiem — the Australian Open runner-up and U.S. Open champion in 2020 — looked physically compromised in a 6-4, 6-4, 6-0 loss to three-time major semifinalist Grigor Dimitrov.

AdHe said: “If it’s any other tournament than a Grand Slam, then I’d withdraw from that event, that’s for sure. Defending champion Novak Djokovic has started his fourth-round match against Milos Raonic at the Australian Open. He'll play either U.S. Open champion Dominic Thiem or Grigor Dimitrov next and he says he doesn't have a preference. Their match is to be followed by eight-time Australian Open champion Djokovic against 2016 Wimbledon finalist Milos Raonic — assuming Djokovic decides he can play. Other men in action include reigning U.S. Open champion Dominic Thiem and the man he beat in that final, Alexander Zverev.

The 10th-seeded Frenchman is a two-time Grand Slam semifinalist, but he can't seem to win anywhere at the moment. ___4:55 p.m.U.S. Open champion Dominic Thiem has moved into the second round at the Australian Open, where he was the runner-up to Novak Djokovic a year ago. Thiem had been 0-3 in Grand Slam finals until emerging for the championship at Flushing Meadows in September. The first tournament of this year’s Grand Slam season began after a three-week delay because of the coronavirus pandemic. Serena Williams begins her latest bid for a 24th Grand Slam singles title in the following match against Laura Siegemund.

There was no certainty until last month that the Australian Open would even be staged. Wimbledon was canceled in 2020, there were no fans permitted at the U.S. Open and very few allowed at Roland Garros. The three-week delay to start the Australian Open this year will mean a slightly different atmosphere — the summer holidays are over, for a start — but that’s unlikely to upset organizers or players. “That’s the first thing I’m looking forward to when I come to Australia, so it was great.

It was a controversial start to the government-mandated quarantine ahead of the Australian Open beginning Feb. 8, 2021. The government-mandated quarantine ahead of the Feb. 8-21 Australian Open had a controversial start. There was some considerable doubt during that second wave whether the Australian Open would even be remotely possible in Melbourne.

They include 2019 U.S. Open champion Bianca Andreescu, whose coach was among those who tested positive, and two-time Australian Open champion Victoria Azarenka.

The top three in the women’s rankings remained as they were before the French Open, with Ash Barty at No. Halep did compete at the French Open, but her 6-1, 6-2 loss to Swiatek in the fourth round didn’t affect the three-time major champion’s ranking.

(AP Photo/Christophe Ena)PARIS – Minutes after suddenly becoming a Grand Slam champion at age 19, while ranked just 54th, Iga Swiatek held a microphone during the French Open trophy presentation and was hesitant for pretty much the only time over the past two weeks. “Two years ago, I won a junior Grand Slam, and right now I’m here. This was, after all, only her seventh major tournament; she'd never been past the fourth round. So it made sense that Swiatek would handle the fourth-seeded Kenin, even if the 21-year-old from Florida won the Australian Open in February and entered Saturday 16-1 in Grand Slam play this year. “Everybody is stressed when they’re playing Grand Slam finals.

4-seeded Kenin moved into the French Open final by beating No. Kenin will carry a 16-1 mark in Grand Slam action this season into Saturday’s championship match against Iga Swiatek of Poland. Swiatek vs. Podoroska was the first women’s semifinal at Roland Garros between unseeded opponents since 1983 — and only one, Swiatek, truly seemed ready for the stage. Swiatek does it with tremendous play at the baseline, picking up balls early and smacking big groundstrokes with thick topspin. I’m, like, not letting my opponents play their best tennis,” Swiatek said.

At the Italian Open, Halep’s final three matches came against Yulia Putintseva, Garbiñe Muguruza and Karolína Pliskova — all three of whom played at the U.S. Open. Halep added a second major trophy by dropping only four games against Serena Williams in last year’s Wimbledon final.

Nadal is expected to return to the French Open, which was postponed in May during the height of the lockdown. Organizers of the Australian Open remain confident the season-opening major will go ahead as scheduled in Melbourne in January.
