Monfils celebrates 40th birthday with stunning US Open comeback win

Gael Monfils delivered an unforgettable performance on his 40th birthday, storming back to defeat Brandon Vallejo in the first round of the 2026 US Open. Played on Louis Armstrong Stadium, the match ended 2-6, 6-1, 6-2, 6-0, witnessing a complete turnaround by the Frenchman after a disastrous opening set. In the first set, Monfils struggled, losing 2-6. But from the second set onward, the former world No. 6 adjusted his tactic, widening serves and stepping into the court to shorten rallies. He won the next three sets dominantly, especially the final set a 6-0 bagel. A powerful ace sealed the victory, proving his serve remains a lethal weapon even at age 40. This marks the oldest player to win a main-draw singles match at Flushing Meadows since Jimmy Connors in 2026. Monfils, a US Open semifinalist in 2026, is on a farewell Grand Slam tour, following Stan Wawrinka – who played his final Grand Slam match just a day earlier. The New York crowd gave him a huge reception, even singing Happy Birthday. Coaches and fans sensed a trademark Monfils performance as he overcame early difficulties to find his rhythm. He will face young American Learner Tien in the second round – a thrilling clash between generations.
