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:
Novak Djokovic lost just one game in his Olympic tennis opener on Saturday to set up a potential blockbuster clash against old rival Rafael Nadal.
Novak Djokovic says he has "high expectations" as he chases an elusive Olympic gold medal, with his confidence unshaken despite a poor year by his stellar standards.
Two-time Olympic gold medallist Andy Murray said he will not compete in the singles competition at the Paris Games and will prioritise the doubles event in the final tournament of his career before retirement.
The Italian said he was "sad and disappointed" to drop out, adding that he had started feeling unwell on Monday after a practice week in Monaco.
Nadal, the 2008 singles gold medallist, will pair up with Alcaraz in a tennis dream team at Roland Garros, looking to also add to the doubles title he won with close friend Marc Lopez at Rio in 2016.
The 37-year-old, a two-time Olympic champion, is planning to play in the singles and doubles at his fifth Games.
The 38-year-old Spanish left-hander has a protected ranking of ninth to put himself into the field for the Flushing Meadows fortnight, which begins on August 26.
"I don't have any limitations in my mind. I still want to keep going and play as long as I feel like I can play on this high level."
"So let's see if at the end of my career it's going to be 25, 30, 15, four (Slams). I don't know. All I want to say is I want to keep enjoying and let's see what the future brings to me."
Spain's Carlos Alcaraz produced an utterly ruthless performance to dismantle Serbia's Novak Djokovic 6-2, 6-2, 7-6 (7/4) in a rematch of last year's Wimbledon final to successfully defend his title on Sunday.
