(AP Photo/Dita Alangkara)2026-01-25T02:25:06Z MELBOURNE, Australia (AP) TikTok influencer and top-ranked Aryna Sabalenka is having to work her way through some rising teenage stars in her bid for a third Australian Open title in four years.Sabalenka, who has drawn praise from fans and other players for her posts on the social media platform about matters on and off the court, held off 19-year-old Vicky Mboko 6-1, 7-6 (1) at Rod Laver Arena on Sunday. Shell play 18-year-old Iva Jovic in the quarterfinals.The 29-seeded Jovic overwhelmed Yulia Putintseva 6-0, 6-1 in 53 minutes at John Cain Arena with six service breaks and winning the first 10 games to secure a spot in the last eight of a Grand Slam for the first time. Obviously, shes No. 1 for a reason and had so much success at this tournament, Jovic said of Sabalenka. But thats what I want I said it last year, I hope to be able to play her this year, because you definitely want to play the best and see how it goes. Coco Gauff, who was still a teenager when she won her first major title in 2023, is back into the quarterfinals in Australia for the third consecutive year after a 6-1, 3-6, 6-3 win over No. 19 Karolina Muchova. Shell next face No. 12 Elina Svitolina, who closed play on Day 8 with a 6-2, 6-4 win over 18-year-old, eighth-seeded Mirra Andreeva. No. 1-ranked Carlos Alcaraz is also in the last 8 for the third straight year, continuing his bid for a career Grand Slam at age 22 with a 7-6 (6), 6-4, 7-5 win over No. 19-seeded Tommy Paul. Hes never gone past the last eight at Melbourne Park, the only one of the four Grand Slam venues where he hasnt won the title. Thats a statistic hes determined to rectify, to the point where hes reworking his serve to a look a little bit more in style with 10-time Australian Open champion Novak Djokovic. Hes unlikely to have the crowd behind him in the quarterfinals, where hell meet local hope and sixth-seeded Alex de Minaur, a 6-4, 6-1, 6-1 winner over No. 10 Alexander Bublik. No. 3 Alexander Zverev, the runner-up in Melbourne last year, beat Francisco Cerundolo 6-2, 6-4, 6-4 and will next meet 20-year-old Learner Tien, the youngest mens quarterfinalist in Australia since Nick Kyrgios in 2015. Tien, who needed treatment for a bloody nose after the third game, beat three-time Australian Open runner-up Daniil Medvedev 6-4, 6-0, 6-3.Djokovics WalkoverThe 38-year-old Djokovic got a walkover into the quarterfinals after Jakub Mensik withdrew 24 hours ahead of their scheduled fourth-round match with an abdominal injury.Djokovics influenceJovic has been getting some good advice from Djokovic, a 24-time major winner, during the tournament. He said hes been happy to help an up-and-coming star with Serbian heritage. Jovic made it clear last year that she wanted a chance to play the World No. 1. Now shell get that chance.Sabalenka, who has joked about waiting for a formal invitation to partner Djokovic in mixed doubles at a major, breezed through the first set in 31 minutes against Mboko but had some difficulty in the second.Mboko saved match points and played well enough to beat many players, but not the two-time Australian Open champion. What an incredible player for such a young age, Sabalenka said of Mboko. Its incredible to see these kids coming up on Tour. I cant believe I say that. I feel like Im a kid!She pushed me so much, and Im happy to be through, Sabalenka added in her on-court TV interview.Sabalenka led the second set 4-1, and then failed to convert three match points while leading 5-4. Mboko slowly took momentum and forced a tiebreaker only for Sabalenka to dominate.It was the 20th straight tiebreaker victory a record for Sabalenka.I try to not to think this is a tiebreak and play point by point, said Sabalenka, who won back-to-back titles in Australia in 2023 and 24 before losing last years final to Madison Keys. I guess thats the key to consistency.Doubling upJovic and Mboko combined later Sunday in the doubles and had match points before the No. 4-seeded Elise Mertens and Zhang Shuai duo clung on in the super tiebreaker to win 7-5, 4-6, 7-6 (10).Theyre both very young, very talented, Mertens said. It was a really tough match.___More AP tennis: https://apnews.com/hub/tennis JOHN PYE Pye is based in Australia and covers sports news across the Asia-Pacific and at major events.
