Other Players Who Have Beat Carlos Alcaraz in 2026

Daniil Medvedev: Alcaraz began the year strongly, winning the Australian Open and Qatar Open, but his first loss came in Indian Wells against Medvedev, the 2021 US Open champion. Medvedev was on a nine-match winning streak when he beat Alcaraz, who had previously overcome players like Grigor Dimitrov, Arthur Rinderknech, Casper Ruud, and Cameron Norrie. Medvedev said, "Carlos is an outstanding player, it’s very tough to play against him and I lost to him many times. Honestly, I will probably play many more times against him and lose many more." Medvedev later lost the Indian Wells final to Jannik Sinner.
Sebastian Korda: Korda caused a major upset by defeating Alcaraz 6-3, 5-7, 6-4 in the Miami Open third round. Ranked 36th at the time, Korda’s win was unexpected. After the match, Alcaraz reflected, "I think the process has been good. Besides the loss today, I think I’m still on the right path. Some things in previous tournaments I didn’t feel comfortable with, but here I started to feel better and better." Alcaraz rebounded to reach his third ATP Tour final soon after.
Jannik Sinner: The Monte Carlo Masters final saw Sinner and Alcaraz battling not just for the title but also the world number one ranking. Sinner won, claiming his third Masters 1000 title of the year and taking the top spot from Alcaraz. Sinner remarked, "It was a bit windy, a bit breezy—different conditions from what the tournament usually brings. Getting back to No. 1 means a lot for me. I’m very happy to win a big title on this surface; I hadn’t done it before and it means a lot." He went on to win five consecutive Masters titles in 2026.
Ben Shelton: Shelton, one of America’s rising stars, recorded a breakthrough victory over Alcaraz in the US Open quarter-finals. Having lost their previous three encounters, Shelton triumphed in a grueling five-set match, 6-7, 6-1, 6-3, 1-6, 7-6, at Arthur Ashe Stadium. Shelton described it as "a war, an epic match, so physical." He praised Alcaraz, saying, "Carlos is one of the greatest champions in our sport already at 23 years old. It’s ridiculous some of the stuff he comes up with sometimes—the most enjoyable match I’ve had in my career, for sure." Shelton advanced to his first major final after beating Frances Tiafoe in the semis but fell to world number two Alexander Zverev in the championship match.
