Top seed Jannik Sinner fought back from a set down to defeat Alexander Zverev 3-6, 6-3, 7-5 in the final of the Vienna Open on Sunday, claiming his fourth title of the season. The victory marks Sinner's second triumph in Vienna, matching the achievement of fellow ATP No. 1 Club members Roger Federer and Andy Murray, and extends his winning streak on indoor hard courts to 21 matches.
Sinner, the world No. 2, dropped his first set of the tournament after world No. 3 Zverev secured the only break of the first set. "It was such a difficult start in this final for me," Sinner admitted. "I went a break down, had some chances in the first set but couldn’t use them. He was serving very well, but I just tried to stick there mentally and play my best tennis when it came.” The Italian responded emphatically in the second set, racing to a 3-0 lead to force a decider.
The final set was a tense, two-hour and 29-minute battle. Despite struggling with a potential thigh issue, Sinner increased his aggression to shorten the rallies. He clinched the crucial break at 5-all with a blistering backhand down the line and won a lengthy rally, snatching the lead before serving out the match. The victory levels his head-to-head series with Zverev at 4-4.
Zverev, the 2021 champion, had won four of the pair's seven previous meetings but was gracious in defeat. “I would like to congratulate Jannik Sinner, whose level has been off the charts for these last two years,” Zverev said. “For me, he is currently the best player in the world. This week, he was simply the best player in Vienna.”
The title, the 22nd of Sinner's career, adds to his successes this season at the Australian Open, Wimbledon, and the China Open (an ATP 500 in Beijing). The 24-year-old has now reached the final in eight of the ten tournaments he has played in 2025 and heads into the final Masters 1000 event of the year in Paris with huge momentum.
