The gap is a veteran's story. Monfils, 39 and in his farewell 2026 season, became the oldest ATP Tour singles champion of the modern era when he won Auckland in February 2025 at the age of 38. His ATP ranking has slipped with a lighter late-career schedule, while the model — which weights recent quality over volume — still rates the level he has shown.
