Carlos Alcaraz has a strong chance to reclaim the ATP No.1 ranking after the US Open 2025, with a title or deep run enough to overtake Jannik Sinner. Alcaraz had held the top spot in the rankings back in 2022 as a 19-year-old.

Jannik Sinner has received a brutal reality check as he prepares to defend his title at the US Open. The world No. 1 recently lifted his fourth Grand Slam trophy at Wimbledon, beating Carlos Alcaraz in the final. If he can retain his crown in Flushing Meadows, he’ll tie Alcaraz on five Majors.

Carlos Alcaraz is hoping to end Jannik Sinner’s dominance of hardcourt Grand Slam events as the two rivals prepare to do battle again at the US Open. World number one Sinner is chasing back-to-back US Open titles in New York to set alongside his Australian Open victories in 2024 and 2025.
