World number one Jannik Sinner just pulled out of the Cincinnati Open, and the timing could not be riskier. If you look closely at how the top tier of men's tennis operates right now, skipping major hard-court tune-up events is a dangerous gamble, even if it is medically necessary. Sinner pointed to an ongoing right knee issue that forced him to skip Montreal and now bypass Ohio entirely. He wants to protect his body. Fair enough. But heading into the US Open without a single match on North American hard courts since winning Wimbledon creates a massive handicap.
The Cost of Zero Hard Court Prep
Tennis isn't just about fitness. It's about rhythm. Sinner lifted his fifth Grand Slam trophy at the All England Club in July, defeating Alexander Zverev in a grueling final. Grass is one thing. Hard courts demand a completely different type of sliding, joint loading, and explosive deceleration.
By withdrawing from Cincinnati, Sinner joins Carlos Alcaraz on the sidelines of the tournament. Alcaraz is dealing with his own long-term wrist issues. When the two top players in the sport arrive in New York with zero competitive momentum on the surface, the draw opens wide for veterans and dark horses who have spent August grinding through matches.
"My right knee has been bothering me and even though we have been working hard with my medical team, I have to accept that I'm not ready to compete yet." — Jannik Sinner
Why the Knee Injury Matters Right Now
We need to talk about the physical toll of modern tennis. Sinner spent time at a specialized clinic in Milan for intensive medical evaluations before making this call. A knee problem for a baseline player who relies on relentless court coverage is no minor inconvenience.
If you are a professional athlete, playing through a compromised knee on hard courts is a recipe for a torn ligament or a multi-month breakdown. Sinner knows this. Winning in 2024 gave him a taste of success in Cincinnati, and he was a finalist last year. Walking away from those ranking points hurts. But preserving his body for a deep run in New York takes priority over everything else.
What to Expect in New York
The final Grand Slam of the season starts on August 30. Without tune-up matches in Canada or Cincinnati, Sinner will have to find his range during the opening week of the US Open.
Expect him to schedule heavy practice sets behind closed doors as soon as he lands. He doesn't lack talent, and his tennis IQ is elite. Still, cold starts at majors rarely go smoothly. Watch the first two rounds of the US Open very closely. If Sinner drops early sets to unseeded players, you will know the lack of hard-court rhythm caught up to him.
Get your popcorn ready. New York is going to be chaotic.
