Jannik Sinner’s third-round victory at the Cincinnati Open didn’t mark the end of his night. While most players would be winding down after a hard-fought match, Sinner chose to head back to the practice courts. At 10:18 p.m., he was seen under the stadium lights, basket in hand, preparing to hit serve after serve.
A win that didn’t feel complete
Sinner had just defeated Gabriel Diallo 6-2, 7-6(6) in a match that lasted nearly two hours and was interrupted by both a power outage and a fire alarm. Despite the win, the world No. 1 wasn’t satisfied with his serving performance. The match had exposed inconsistencies he couldn’t ignore, and instead of celebrating, he turned to his team with a simple directive: “Let’s go to the court.”
Late-night practice fueled by frustration
What followed was an intense hour-long session focused entirely on serving. Sinner reportedly hit 100 serves against the back fence, working on rhythm, placement, and consistency. His team watched as he repeated the motion again and again, determined to iron out the flaws that had surfaced earlier in the evening.
A glimpse into Sinner’s mindset
This late-night effort reflects Sinner’s relentless drive to improve, even after a win. His decision to train instead of rest shows a level of commitment that sets him apart. While others may have seen the match as a success, Sinner viewed it as a stepping stone—and an opportunity to sharpen his game further.
Looking ahead in Cincinnati
With the next round approaching, Sinner’s focus remains locked in. His actions in Cincinnati suggest that he’s not just chasing victories—he’s chasing perfection. Whether this extra work pays off in the next match remains to be seen, but one thing is clear: Sinner’s hunger to improve never sleeps.
