Insights

Peak came in 1991 with his only quarterfinal

Hlasek’s best Grand Slam result was a single quarterfinal, and it came at the 1991 French Open at age 26. That season also included R32 at the US Open and R64 at Wimbledon, making 1991 his clear high-water mark.

Strongest stretch ran from 1987 through 1991

Across those five seasons, he reached at least the round of 32 in 13 of 18 completed Slam appearances, including four straight years with a round-of-16 or better result somewhere. The run is anchored by 1987 Wimbledon R16, 1988 US Open R16, 1989 French Open R16, and the 1991 quarterfinal.

Clay was his most productive surface in the data

His best result, the 1991 French Open quarterfinal, came on clay, and he also reached the French Open round of 16 in 1989. By contrast, his Australian Open results never went beyond the round of 32.

Late-career decline was abrupt after age 29

At age 29 in 1994, he still reached Wimbledon R32 and the Australian Open R64, but by age 30 in 1995 he fell to R64 at the US Open and R128 at both Wimbledon and the French Open. At age 31 in 1996, he recovered only to two round-of-16 finishes.

His Slam record is built on consistency more than deep runs

Over 49 tournaments and 107 matches, Hlasek finished 58-49, with only one quarterfinal and five round-of-16 results. The remaining best-results bucket is dominated by 12 round-of-32 finishes, showing frequent mid-round exits rather than repeated late-stage breakthroughs.
