Tallon Griekspoor

Insights

Only one second-week run, and it came at Roland Garros in 2025

Across 23 Grand Slam tournaments, Griekspoor’s best result is one R16, with four R32s and six R64s. That lone fourth-round appearance came at the 2025 French Open, at age 28.

His Grand Slam peak arrived late in the sample, after years of mid-round exits

From 2020 through 2023, he never advanced beyond the third round: his best results were R64 in 2021 and 2022, then R32 in 2023. The step up to R16 only appears in 2025, after 17 prior Slam matches had already been played.

2024 was his most productive Slam season by depth across all four majors

He reached at least the third round in every Slam that year: R32 at the Australian Open, French Open, and US Open, plus R64 at Wimbledon. That is his only season in the data with four completed Slam appearances all finishing inside the top 64 or better.

His best hard-court Slam stretch came in 2023-2024 before slipping back in 2025-2026

On hard courts, he improved from R32 at the 2023 Australian Open to R32 at the 2024 Australian Open and R32 at the 2024 US Open, then fell to R128 at both hard-court majors in 2025 and 2026. The sequence shows a clear peak followed by a sharp drop.

His overall Slam record is close to break-even but still negative

He has 17 wins and 23 losses across 40 matches, a 43% win rate. That means he has played more than twice as many matches as tournaments entered, but still has not reached a winning record at the majors.
