Insights

Peak came in 1998–1999

His only semifinal was the 1998 Australian Open at age 23, followed by a quarterfinal at the 1998 US Open and another quarterfinal at the 1999 Australian Open. That three-event stretch is the clear high point of his Grand Slam run.

Best results were concentrated on hard courts and grass

All of his top finishes came at the Australian Open, US Open, or Wimbledon: one semifinal, two quarterfinals, and one round-of-16. He never reached the quarterfinal stage at the French Open.

Strongest season by depth was 1998

In 1998 he reached the semifinals in Melbourne, the quarterfinals in New York, and still advanced to the third round at Wimbledon and Roland Garros. That was his only season with multiple deep runs across different Slams.

Late-career results settled into first-week exits

From 2001 through 2005, every Grand Slam result was a first- or second-round exit: R128, R64, or R32. His best result in that span was the 2003 US Open and Wimbledon, where he reached the round of 32.

Career volume matched exactly with a .500 record

He played 41 Grand Slam tournaments and 82 matches, finishing with a 41-41 record. That means every match won was offset by a loss, producing an exact 50% win rate across the full Slam career.
