3 Top Moments From Zverev vs Khachanov US Open Semifinal Thriller

Alexander Zverev is heading back to a Grand Slam final, and he had to survive a genuine dogfight to get there. The World No. 2 outlasted Karen Khachanov 6-3, 7-6, 7-6 in a US Open semifinal that was far closer than the scoreline suggests, marking Zverev's sixth career Grand Slam final appearance.

Khachanov, playing with nothing to lose, pushed the top seed into multiple tie-breaks and even looked poised to force a fourth set before Zverev found his best tennis when it mattered most, closing out the match with a pair of clutch aces. Here's a breakdown of what made this match must-watch tennis.

The Sun Became a Third Opponent One of the strangest subplots of the semifinal had nothing to do with either player's game. During the third set, sunlight kept flashing across the court as hospitality box doors opened and closed, sending glare straight into both players' eyes. Zverev was visibly frustrated and raised the issue with the chair umpire, calling it a lottery as to whether players could actually see the ball toss. It's a reminder that even at the highest level of tennis, conditions outside a player's control can shape momentum in a match.

Khachanov Refused to Fold Despite dropping the first set relatively comfortably, Khachanov didn't roll over. He dragged Zverev into tie-break territory not once but twice, showing off the kind of grit that has made him a dangerous floater in draws for years. At one stretch in the third set, it genuinely looked like he might force a decider, which would have flipped the entire complexion of the match and put real pressure on Zverev heading into a potential final.

Zverev's Clutch Finish When it mattered most, Zverev delivered. After clawing back from a significant deficit late in the third set, he sealed the win with back-to-back aces in the final moments, the kind of nerve-steadying serves that separate top-two players from the rest of the field. It was a fitting exclamation point on a match that could have easily gotten away from him.

Why This Semifinal Stood Out This wasn't a straightforward beatdown. Zverev needed every bit of his experience and composure to get past a determined Khachanov, and the match doubled as a stress test heading into a Grand Slam final. For fans, it's the kind of match that reinforces why tennis at this level is as much mental as it is physical — weather glare, momentum swings, and all.

Zverev now moves on to his sixth Grand Slam final, continuing to build a resume that's long on deep runs. Whether he can convert this one remains the next big question for tennis fans following the US Open.
