Insights

Two clear peaks, both at Roland Garros

Altmaier’s best Grand Slam results are two R16 finishes, and both came at the French Open: 2020 at age 22 and 2025 at age 26. No other major produced a result better than R32.

His Grand Slam record is built on clay, not across all four majors

Across 21 tournaments and 35 matches, his overall record is 14-21. The French Open accounts for his strongest outcomes, while Wimbledon and the Australian Open never got beyond R64, and the US Open only reached R32 once.

2025 was his most productive Slam season

In 2025 he reached R16 at the French Open, R32 at the US Open, and R64 at the Australian Open, giving him three results inside the top three rounds. That was his deepest and most balanced season across the four majors.

2026 marked a sharp drop-off

All four of his 2026 Slam results were R128, at age 27. That is a clear step down from 2025, when he had already reached R16, R32, and R64 in the same calendar year.

His Slam career has been intermittent, not continuous

The career span is listed as 2020, 2022-, with no Grand Slam results shown for 2021. That gap separates his first R16 run in 2020 from the later stretch that resumed in 2022 and continued through 2026.
