Top Seeds Face Stiff Challenges as US Open Enters Crucial Stage

Jannik Sinner and Iga Swiatek prepare for tough fourth-round matches, with several notable upsets already shaking the tournament.

Jannik Sinner, the world number one, will face Tommy Paul in a highly anticipated fourth-round match.
Despite a doping controversy, Sinner has been in top form, dropping only one set in the tournament so far.
Tommy Paul aims to leverage home-court advantage and a varied game plan to counter Sinner's powerful baseline play.
Iga Swiatek, aiming for her second US Open title, will face a challenging opponent in Liudmila Samsonova.
Several top players, including Novak Djokovic and Coco Gauff, have been eliminated early, adding unpredictability to the tournament.
