Jannik Sinner's withdrawal from the Cincinnati Open has sent ripples of concern through the tennis world, arriving just weeks before the US Open. The world number one cited his right knee in a formal statement, noting that despite intensive work with his medical team, he simply was not ready to compete. He added that his focus had already shifted entirely toward being fit for New York.
The decision drew attention from Dr. Giovanni Di Giacomo, a physician who worked on the ATP Tour during the 1990s. Speaking to journalist Marco Beltrani, Di Giacomo offered a grounded read of the situation, describing Sinner's condition as an overload syndrome, a problem he stressed is far from unique to elite tennis. He pointed out that even the sport's best players carry the same biological vulnerabilities as everyone else, including tendons, ligaments, and cartilage that can only absorb so much stress.
Di Giacomo framed the Cincinnati skip as a calculated call rather than a crisis, suggesting that Sinner's medical staff made a sensible risk assessment. In his view, protecting the knee now in order to arrive at Flushing Meadows in better shape is straightforward sports medicine logic.
Interestingly, Di Giacomo also pushed back against any notion that overload injuries are a modern problem driven by today's demanding schedule. He recalled dealing with the very same issues when he first joined the ATP circuit more than three decades ago, while crediting advances in training, monitoring, and injury prevention for improving outcomes compared to that era.
Sinner has now shown a pattern of skipping warm-up events before major titles, having won both the Australian Open and Wimbledon this year without prior tournament play. TennisDraw users have consistently backed Sinner deep into Grand Slam bracket picks, and that confidence is unlikely to waver heading into the US Open.
