Insights

Peak came early, at age 19

His best Grand Slam result was the 1982 Australian Open quarterfinal, reached at age 19. That stands out as his only run beyond the round of 16 across 22 tournaments and 41 matches.

Wimbledon produced his deepest late-career run

After the 1982 peak, his best Wimbledon showing was the 1985 round of 16 at age 22. He then reached only the round of 32 at Wimbledon in 1986 and the round of 64 in 1987 before a first-round exit in 1989.

US Open was his most frequent stage

He appeared at the US Open seven times, more than any other Slam in the data. His US Open results ranged from a 1980 round of 32 to three round-of-128 exits, with his best later result being round of 64 in 1981 and 1988.

Australian Open appearances were concentrated in the middle of his career

He played the Australian Open five times, all between 1982 and 1988. That stretch includes his quarterfinal, plus round-of-64 finishes in 1983, 1985, and 1988, and a round-of-128 exit in 1984.

His results trended downward after 1985

From 1980 through 1985 he reached at least the round of 64 in six of nine appearances, including the quarterfinal and the Wimbledon round of 16. From 1986 onward, none of his nine Slam results improved beyond round of 32.
