Jannik Sinner Battles Through Cramps to Claim Vienna Title Against Zverev
The 2025 Erste Bank Open final had everything—drama, tension, and a healthy dose of physical struggle. Jannik Sinner, currently ranked World No. 2, managed to push through visible cramping issues to defeat Alexander Zverev in a nail-biting three-set match with a final score of 3–6, 6–3, 7–5. But let’s be honest, watching Sinner grimace through those cramps was about as comfortable as sitting through a dentist appointment.
Sinner’s Rocky Road to the Final
Before we dive into the final, let’s talk about how Sinner even got there. The Italian absolutely dominated his opening match against Daniel Altmaier, steamrolling through with a 6–0, 6–2 victory in just 58 minutes. According to the ATP, this was his quickest win of 2025. Not too shabby, right?
From there, Sinner kept the momentum going. He worked his way past Flavio Cobolli in the round of 16, then faced Alexander Bublik in the quarterfinals. The semifinal matchup against Alex de Minaur was particularly impressive—Sinner won in straight sets (6–3, 6–4), booking his spot in the final. This marked his eighth final appearance of the season, a feat only Novak Djokovic has managed to achieve in consecutive years. No pressure or anything.
The Final: When Your Body Decides to Stage a Protest
Now, let’s get to the main event. The final against Zverev started off rough for Sinner. He dropped the first set 3–6, and you could already see signs that something wasn’t quite right. By the time the score reached 6–3 in the second set (with Sinner taking it) and then 3–3 in the third, the cramping became impossible to ignore.
Picture this: You’re playing at the highest level of professional tennis, every point matters, and your muscles are basically screaming at you to stop. At 15–30 in that crucial third set, Sinner was visibly struggling. The cameras caught him wincing, stretching, and doing everything short of begging his legs to cooperate. It was the kind of moment that makes you wonder how these athletes push through when most of us would be reaching for the ice pack and calling it a day.
Grit, Determination, and Probably Some Choice Words
Despite the physical turmoil, Sinner somehow found a way to dig deep. Maybe it was pure determination. Maybe it was the roar of the crowd. Or maybe it was just the realization that he’d come too far to let some pesky cramps ruin his day. Whatever the reason, he clawed his way back, eventually taking the third set 7–5 and claiming the championship.
Zverev, who reached the final as the tournament’s second seed after his own impressive semifinal win against Lorenzo Musetti (6–4, 7–5), put up a solid fight. But when Sinner’s on, even when he’s clearly not at 100%, he’s a force to be reckoned with.
What This Win Means for Sinner

This victory at the Vienna Open adds another trophy to Sinner’s growing collection and reinforces his position as one of the top players on the ATP tour. His ability to win despite obvious physical struggles shows the kind of mental toughness that separates good players from great ones. Sure, he might have looked like he was running a marathon on wobbly legs toward the end there, but he got the job done.
It’s also worth noting that Jack Draper, another promising player, didn’t participate in the tournament due to an arm injury. The absence of key players always shifts the dynamics, but Sinner’s performance throughout the week proved he was the man to beat regardless of who showed up.
Final Thoughts
Jannik Sinner’s triumph at the 2025 Erste Bank Open wasn’t just about skill—it was about heart, resilience, and the ability to push through when your body is actively working against you. Watching him battle through those cramps was equal parts inspiring and uncomfortable, but that’s what makes these moments memorable. Zverev played well, the competition was fierce, and Sinner emerged victorious. Not a bad way to secure your eighth final win of the season, even if your legs were staging a mutiny.
