In the 90 minutes between Jannik Sinner’s defeat by Carlos Alcaraz in the US Open final and his post-match debrief, his mind had already shifted. Rather than dwelling on the pain of losing his US Open title and No 1 ranking, he was thinking about the future.
Sinner felt his game was too predictable, even one-dimensional, compared with Alcaraz, whose deep toolbox of shots left him uncomfortable and unable to find rhythm on the court. As a result of that discomfort, Sinner made a decision. The 24-year-old resolved to make significant changes to his game in pursuit of becoming a better, more complete tennis player and keeping up with his rival, even if he might suffer in the short term.
