The core of Agassi’s comment, which quickly went viral on social media, was his verdict that Sinner has “no excuse to run into a wall” during high-stakes matches, referring to the 22-year-old Italian’s repeated pattern of sticking to ineffective, pre-planned tactics even when opponents have clearly neutralized his strengths. Agassi, who has previously trained with Sinner for short stints and been open about his admiration for the young player’s raw talent, cited Sinner’s three-set loss to Daniil Medvedev in the 2024 Indian Wells Masters 1000 final as a prime example of the issue. “Jannik has every tool you could possibly ask for: a 140mph first serve, a forehand that can hit winners from any position on the court, net skills that are better than 90% of the top 20 players right now,” Agassi explained during the segment. “But in that final against Medvedev, he spent the entire second set camped 6 feet behind the baseline, hitting the same crosscourt forehand over and over even when Medvedev was camped out waiting for it. That’s running into a wall, and there’s zero excuse for it when you have the skill set to mix up your game at any time.” The 2024 Australian Open champion has long been open about his tendency to stick to familiar game plans even during losing streaks, and Agassi’s comments have sparked widespread conversation about whether the young star needs to adjust his in-match decision-making to reach the next level of consistent Grand Slam contention. Agassi went on to note that the difference between elite players who win double-digit Slams and players who only win one or two is almost always their ability to adjust tactics mid-set, rather than relying on what worked in previous rounds. He drew parallels to his own early career, when he refused to adjust his aggressive baseline game to slower clay surfaces and struggled to win Roland Garros for years until he adjusted his approach. In response to Agassi’s comments, Sinner spoke to reporters ahead of the Rome Masters this week, saying that he takes every piece of advice from a legend like Agassi extremely seriously. “I watched the clip of Andre’s comments yesterday, and he’s right about a lot of what he said,” Sinner noted. “I’ve been working with my coaching team on adding more in-match adjustments to my game, and I’m excited to test those new approaches in the clay season leading up to Roland Garros. This kind of honest feedback is exactly what I need to get better.”
