US Open: Alexander Zverev survives another 5-set marathon, making ominous history as top seed in the process

Key Points:

• Alexander Zverev, the No. 1 seed at the 2026 US Open, has played two consecutive five-set matches totaling over nine hours, marking an unprecedented start for a top seed in the Open Era.
• Despite winning both matches, Zverev's performance showed inconsistency, with strong serving but struggles on break points and baseline play, raising questions about his form since his Roland-Garros title earlier this year.
• Zverev's upcoming third-round opponent is No. 25 seed Alejandro Tabilo, with a relatively easier path ahead due to early exits of higher seeds like Felix Auger-Aliassime, Alex de Minaur, and Novak Djokovic.
• The men's draw has opened up significantly with top contenders out or returning from injury, presenting Zverev with a favorable opportunity, though his vulnerability might also boost American players aiming to end their 23-year Grand Slam drought.
• Notable threats remaining include No. 7 Daniil Medvedev and top American players Ben Shelton, Taylor Fritz, and Frances Tiafoe, while former US Open champion Andy Roddick provided commentary during Zverev's match.
