The Cincinnati Open quarterfinal between Alexander Zverev and Ben Shelton proved to be anything but routine. Zverev looked sharp from the start, but as the match wore on, fans saw him battle through a health scare that left everyone wondering what was really going on. One of the tour’s best athletes suddenly had to fight for more than just points, and it changed the whole vibe inside the stadium.
What Happened to Alexander Zverev During the Cincinnati Open Quarterfinal?
Even though Zverev cruised to victory, his health grabbed the headlines. The German player has been managing health issues for months, and those problems showed up once again during his match against Shelton. This wasn’t the first time Zverev’s struggles were obvious on court, but it was a clear reminder of how quickly things can go sideways.
The real drama started about halfway through the contest. Zverev had to take a medical timeout when he started having serious trouble breathing in the quarterfinal. The 28-year-old was visibly struggling and even mentioned that his head was spinning during the pause.
He ended up using an inhaler during the medical timeout, making it clear he was dealing with real breathing problems. This all happened as he led Shelton 2-0 in the second set. TV commentator Jim Courier questioned what was causing Zverev’s issues, especially since he’s usually considered one of the best-conditioned guys on the tour.

Zverev seemed fine when the match kicked off, but things started to unravel near the end of the first set. His problems kept getting worse from there. Despite all that, he managed to keep playing after the medical help, but fans and fellow tennis watchers were left unsure about what his future might look like.
How Did Zverev Overcome Ben Shelton and Advance in Cincinnati?
The strange health issue didn’t stop Zverev from powering through the match. He rolled over Shelton with a 6-2, 6-2 win, needing only 77 minutes to seal it. Zverev’s first serve was especially strong, winning 81% of those points, and he defended well by saving the only break point he faced. His serving made it tough for Shelton to get any real momentum or return opportunities.
Shelton came in riding a nine-match win streak and had been playing some of his best tennis. But on this day, he just couldn’t find the rhythm against Zverev. The American smashed 12 aces, but winning only four out of his 19 second-serve points made it hard for him to stay in contention.
Afterward, Zverev spoke openly about how he felt after the win. He said he wasn’t feeling great and hoped he’d be refreshed and back to 100% for his next match. Zverev shared that he came out feeling the best he had in months, but the good feeling faded quickly toward the end of the first set and kept getting worse as the match went on.
