Gael Monfils turned 40 and won a Grand Slam match on the same day, coming back from a set down to beat Adolfo Daniel Vallejo 2-6, 6-1, 6-2, 6-0 on Louis Armstrong Stadium, where the crowd sang Happy Birthday to him at the end.
He is the first player aged 40 or over to win a singles match at the US Open since Jimmy Connors in 1992 — a comparison that says as much about how long Monfils has kept a body built on explosive movement in one piece as it does about the record itself. This is his farewell season.
He faces the 14th seed Learner Tien next, a player nineteen years younger than him.
