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:
Wimbledon will break with tradition and replace line judges with electronic line calling from next year's championships, the All England Club confirmed on Wednesday.
Aryna Sabalenka has set her sights on reclaiming the world number one spot and can close the gap on Iga Swiatek with a good run at the Wuhan Open, which is returning on Monday after a five-year absence.
Four-time Grand Slam winner Carlos Alcaraz made short work of China's Shang Juncheng on Saturday, defeating him in straight sets to breeze through to the Shanghai Masters third round.
Sinner now has to turn his attention to the Shanghai Masters, where he could end up facing Alcaraz again.
The four-time Grand Slam champion from Spain edged a captivating final 6-7 (6/8), 6-4, 7-6 (7/3) for his fourth ATP crown of the year and 16th overall.
Jannik Sinner ignored the bubbling controversy over his steroid case and a roaring home crowd to set up a China Open final against Carlos Alcaraz on Tuesday.
The International Tennis Integrity Agency (ITIA) had cleared the Italian of wrongdoing in August, and weeks later he won the US Open for his second major title.
Carlos Alcaraz welcomed the addition of Rafa Nadal to Spain's Davis Cup team for the quarter-finals in November and hoped the event in Malaga will not mark the end of the 22-times Grand Slam champion's career.
Aryna Sabalenka said Tuesday that she wants to cap off a stellar year by returning to the top of the world rankings.
"I'm too far away from that level," he said. "I hope I'll reach it one day, but it's really impossible," said Alcaraz.
