Monfils wins US Open first round on 40th birthday

French veteran Gael Monfils marked his 40th birthday with a victory in the first round of the U.S. Open on Tuesday, September 1, 2026, advancing to the second round of his final Grand Slam tournament. Playing on Louis Armstrong Stadium, Monfils overcame a shaky start to defeat Adolfo Daniel Vallejo of Paraguay 2-6, 6-1, 6-2, 6-0. Monfils, who is set to retire at the end of the season, celebrated his milestone birthday by showcasing his signature flair and resilience. After dropping the opening set, the former world number six rallied strongly, dominating the subsequent sets with his dynamic play. The crowd in New York offered enthusiastic support throughout the match, joining in an impromptu rendition of "Happy Birthday" for the Frenchman after his win. "You guys always make it electric, amazing," Monfils said in an on-court interview, expressing his gratitude for the atmosphere. "Lets keep it going for the second one." The victory made Monfils the oldest man to record a win in the main draw of the U.S. Open since Jimmy Connors in 1992, who also achieved the feat on his 40th birthday. This marks Monfils's 18th appearance at the U.S.
