Gael Monfils defeats Adolfo Daniel Vallejo at the U.S. Open, playing on his 40th birthday. After losing the first set 2-6, Monfils rebounds to win 6-1, 6-2, 6-0 and advances to the second round. Multiple outlets describe a strong reaction from the crowd as he bows to spectators.
Several reports highlight the significance of the occasion: Monfils is noted as the oldest man to win a U.S. Open match since 1992, when Jimmy Connors won at age 40. BBC Sport and Yahoo Sports both mention the crowd singing “Happy Birthday,” framing it as a standout moment alongside the match result. Other coverage focuses more directly on the turnaround after the opening set and the final score, while not adding additional historical detail beyond the win itself.
