Monfils, 40, rallies past Vallejo to reach US Open second round

Gael Monfils celebrated his 40th birthday with a dramatic 2-6, 6-1, 6-2, 6-0 comeback win over Adolfo Daniel Vallejo to advance to the second round of the US Open, delivering a memorable night for a veteran showman as he pursues one of his final Grand Slams. The French star, who will retire after this season, drew cheers from a New York crowd with flamboyant shotmaking and celebratory bows, including a post-match moment in which the crowd sang Happy Birthday. Monfils became the oldest player to win a main-draw US Open match since Jimmy Connors in 1992, underscoring the longevity of his entertaining style. The victory extended his farewell campaign and came on the same day as other veterans marking career milestones, while reaffirming his status as a fan favorite for his electric left-handed play and showmanship. He thanked the crowd for their support and said he aimed to keep playing well and making memories in the tournament that has long defined his career. The momentum from this win sets up a second-round date with Learner Tien as he bids to close out a storied time on the tour.
