Former world number one and two-time Grand Slam winner Simona Halep announced her retirement from professional tennis on Tuesday after losing in the first round at her home event in Cluj.
Two-time Wimbledon champion Petra Kvitova will return to action this month after a 15-month maternity break, with the Czech set to play in three tournaments in the United States.
"He has lost only four or five matches in the past year, so it's crazy. I know people say who's better out of us. They say Jannik is better or some say me. It's all discussion."
World number one Jannik Sinner will not defend his ATP 500 title in Rotterdam as the Italian's "body needs time to rest" after winning the Australian Open, tournament organisers announced Monday.
Double Australian Open champion Jannik Sinner set his sights on mastering clay and grass courts to make himself a complete player after the Italian claimed his third hardcourt Grand Slam title on Sunday.
The 23-year-old came through a tense battle between the world's top two players 6-3, 7-6 (7/4), 6-3 on Rod Laver Arena, raising his arms in the air and looking to the sky in celebration.
The victory earned the Italian world number one his third Grand Slam crown.
The Australian Open, the first Grand Slam of the year, ends on Sunday when defending champion Jannik Sinner faces Alexander Zverev for the men's title. AFP looks back on five memorable storylines from the past two weeks in Melbourne:
Italian top seed Jannik Sinner took down ailing Briton Jack Draper 7-5, 7-6 (7/3), 6-2 to reach the US Open final on Friday, overcoming muggy conditions in a chaotic match at Arthur Ashe Stadium.
Pegula has now won 15 of 16 matches on the US summer hard court swing which saw a title in Toronto and defeat in the Cincinnati final to Sabalenka.
Sabalenka sent down 34 winners to the 13 of the 23-year-old American in the tie.
Medvedev still leads their head-to-head 7-6, although the Italian Sinner has won six of their last seven meetings.
World number one Jannik Sinner reached his first US Open semi-final on Wednesday with a four-set victory over 2021 champion and two-time runner-up Daniil Medvedev.
Jessica Pegula became the fourth American to reach this year's US Open semifinals on Wednesday by stunning world number one Iga Swiatek as Jack Draper broke through to his first Grand Slam last-four.
Sinner is the only top-four player left in the men's draw following the exits of Novak Djokovic, Carlos Alcaraz and Alexander Zverev.
Emma Navarro reached her first Grand Slam semi-final at the US Open on Tuesday with a straight-sets victory over Paula Badosa whose challenge dramatically collapsed.
The 23-year-old Italian is the only man to have made the quarter-finals of all four majors this season.
Top seed Swiatek, who won the title two years ago, showcased her all-court game in a straightforward 6-4, 6-1 win over Russian Liudmila Samsonova to open the evening session at Arthur Ashe Stadium and warned she was only going to improve.
