Oldest Masters 1000 Semifinalists

At the top of the list for oldest Masters 1000 semifinalists stands Novak Djokovic, who reached the semifinals of the 2025 Shanghai Masters aged 38 years and 125 days, becoming the oldest men’s singles semifinalist in ATP Masters 1000 history — a category that formally begins with the series’ launch in 1990. In Shanghai, Djokovic defeated Zizou Bergs in the quarterfinals, 6-3, 6-4, to reach his 80th career Masters 1000 semifinal, extending his own record at that level. That run pushed the longevity ceiling beyond the mark he had set earlier in the same season at the 2025 Miami Open, where he had become the oldest Masters 1000 semifinalist at 37 years and 10 months after beating Sebastian Korda 6-3, 7-6(4).

Behind him, the previous gold standard belonged largely to Roger Federer, who reached the semifinals at both Miami 2019 and Indian Wells 2019 aged 37 years and 7 months, with the Miami run ending in the title. Other entries near the top of the list include Djokovic at Shanghai 2024, Federer at Paris 2018, Shanghai 2018, and Cincinnati 2018, while John Isner was also a notable non-Big-Three marker with his Canada/Toronto 2021 semifinal run aged 36.

In this record, the milestone is not simply entering the draw, but surviving an elite Masters 1000 field to reach the final four: Djokovic has set the current ceiling at 38, Federer remains the defining late-career reference before him, and Isner represents the most notable serve-driven longevity case outside the Big Three.
