Both Jannik Sinner and Carlos Alcaraz advanced to the second round of the US Open, albeit with some challenges. Sinner, the world number one, overcame a poor start against Mackenzie McDonald, winning 2-6, 6-2, 6-1, 6-2, marking his return after being cleared from a doping investigation. Alcaraz, the reigning champion, faced a tougher match against Australian qualifier Li Tu but ultimately prevailed 6-2, 4-6, 6-3, 6-1, extending his Grand Slam winning streak to 15 matches. Despite dropping a set, Alcaraz's powerful performance included 50 winners, although he also recorded 30 unforced errors. Looking ahead, both players are on a collision course for a potential semi-final matchup, with Alcaraz preparing to face Botic van de Zandschulp next. The tournament also saw other notable results, including early exits for Stefanos Tsitsipas and a marathon match involving Dan Evans.
