Peak years came in a tight 2001-2004 window

All four semifinal runs were packed into 2001, 2003 and 2004: Australian Open and French Open in 2001, Wimbledon in 2003 and 2004. That same span also includes three quarterfinals, making it his clear Grand Slam peak.

Wimbledon was his strongest single major

Wimbledon produced his best concentration of deep runs: one semifinal in 2003, another in 2004, plus a quarterfinal in 2005 and a round-of-16 in 1998. No other Slam shows as many finishes at R16 or better.

Australian Open was the most volatile Slam

His Australian Open results range from two semifinals in 2001 to a quarterfinal in 2003 and 2004, then slide to R32 in 2007 and 2008 and R128 in 2010. That spread is wider than at his other majors.

Late-career decline was sharp after age 27

At age 27 in 2005, he reached the French Open round of 16 and Wimbledon quarterfinals. From age 28 onward, his best Grand Slam result was only R32, and his final appearance at 31 ended in R128 at the 2010 Australian Open.

His Grand Slam record was built on consistency, not just peaks

Across 43 tournaments and 121 matches, he went 78-43, a 64% win rate. He also reached at least the third round in multiple seasons, including 2000, 2001, 2003, 2004 and 2005, showing repeated competitiveness beyond the semifinal spikes.
