Jannik Sinner has been absolutely unstoppable over the past few months, and his fellow competitors are taking notice. In March, the Italian star joined an elite club by becoming just the eighth man in history to complete the "Sunshine Double," winning back-to-back titles at Indian Wells and Miami. But he didn't stop there.

Sinner reclaimed the world No. 1 ranking from Carlos Alcaraz after defeating him in the Monte Carlo Masters final. Then, in Madrid, he made history as the first player ever to win five consecutive Masters 1000 events. His incredible run continued in Rome, where he cruised past Sebastian Ofner, who managed just seven winners and lost his serve three times.

But according to Casper Ruud, it's not about Ofner's struggles—it's about Sinner's sheer brilliance. The Norwegian, who returned to the top two in the rankings earlier this year, shared his thoughts on Sinner's form ahead of his own straight-sets win over Jiri Lehecka.

"I played him last year in Rome, and even then, I said quite openly that it was a crazy level that I felt and saw and was a witness of," Ruud told Dutch broadcaster Ziggo Sport. "Playing the match, you just realize how good he is."

Ruud also addressed a common criticism of Sinner's game—that his groundstrokes are too robotic, lacking personality due to their mechanical precision. The Norwegian disagrees entirely. "I see a lot of people saying Jannik is a little bit too much of a robot," Ruud said. "But when you realize how difficult tennis is, and you can make it look robotic, it shows how good you are. It should be a compliment. To make something as complex as tennis appear so simple and straightforward is incredibly impressive."

With every player now chasing Sinner, the Italian continues to raise the bar. "He keeps showing off to players and beating everyone," Ruud added. "It's incredible and kind of inspirational to see what he is doing these days."

As Ruud prepares to face Lorenzo Musetti or Francisco Cerundolo in the next round, one thing is clear: Sinner's dominance is reshaping the sport, and his rivals can only admire the machine-like precision that makes him so tough to beat.
