Peak Slam run came at Wimbledon in 1998

His best Grand Slam result was a quarterfinal at Wimbledon in 1998, when he was 28. That was his only quarterfinal and one of just three results better than the third round across 41 tournaments.

Australian Open was his strongest major by deep runs

He reached the Australian Open round of 16 once and the round of 32 twice, including his best Australian Open showing in 1991 at age 20. Across the four majors, that is his clearest concentration of early-round success.

1998 was his standout season across the majors

In 1998 he produced his best Wimbledon result, reached the US Open round of 16, and also made the Australian Open round of 64. That was his only season with multiple results at R16-or-better level.

Late-career results were mostly first-round exits

From 1999 through 2001, he went 0-for-11 in matches beyond the opening round, with every result at R128 except two R64 finishes at the 2001 Australian Open and US Open. The pattern marks a clear drop from his 1998 peak.

His Slam career was long but modest in volume

He played 41 Grand Slam tournaments and 73 matches from 1991 to 2001, finishing with a 32-41 record. That workload produced only one quarterfinal, two round-of-16 appearances, and seven round-of-32 appearances.
