Roger Federer made a nostalgic return to the US Open on September 3, 2024, marking his first appearance at Arthur Ashe Stadium since his retirement in 2022. The tennis legend received a warm ovation from the crowd while attending a women's singles quarter-final match between Aryna Sabalenka and Zheng Qinwen. Federer, a five-time US Open champion, expressed concerns about the inconsistency in doping regulations related to current World No. 1 Jannik Sinner, who faced scrutiny for testing positive for a banned substance. He emphasized the need for clarity in how such cases are handled in the sport. Sabalenka continued her strong performance at the tournament, winning her match decisively to reach her fourth consecutive semi-final. Federer's presence and his ongoing projects, including a new visual biography, highlight his enduring influence in tennis even after retirement.
