Players Who Have Defeated Carlos Alcaraz in 2026

• Daniil Medvedev: After starting the year strong with wins at the Australian Open and Qatar Open, Alcaraz met his first loss of 2026 at Indian Wells. Medvedev, the 2021 US Open champion, defeated Alcaraz following his streak of nine straight Tour wins. Medvedev remarked, "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 final to Jannik Sinner.
• Sebastian Korda: The American stunned Alcaraz at the Miami Open third round with a 6-3, 5-7, 6-4 win. Ranked 36th at the time, Korda’s performance was a highlight. Alcaraz responded positively, saying he felt he was improving despite the setback, "Some things in previous tournaments I didn’t feel comfortable with, but here I started to feel better and better." This loss was followed by Alcaraz reaching his third ATP Tour final of the year.
• Jannik Sinner: Their match in the Monte Carlo Masters final was not just for the trophy but also the No. 1 world ranking. Sinner clinched the title and reclaimed the top spot from Alcaraz, marking his third Masters 1000 win this season and continuing a streak of five consecutive Masters titles. Sinner reflected on the match conditions, "It was a bit windy, a bit breezy. Different conditions from what the tournament has brought." He added, "Getting back to No. 1 means a lot for me... I am very happy to win a big title on this surface. I haven’t done it before and it means a lot to me."
• Ben Shelton: America's emerging star delivered a defining moment by defeating Alcaraz in a grueling US Open quarter-final. Shelton, who had lost all three previous matches against Alcaraz, won 6-7, 6-1, 6-3, 1-6, 7-6 at Arthur Ashe Stadium. Describing the encounter, Shelton called it "a war, an epic match, so physical." He praised Alcaraz, "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 that 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.
• Zizou Bergs: Most recently, Bergs ended Alcaraz’s run in Shanghai, marking the latest upset against the young Spanish star.
