Three Grand Slam titles, all in a four-year peak

Kodeš’s best results include 3 titles, 2 finals, and 1 semifinal. The titles came at the French Open in 1970 and 1971, and Wimbledon in 1973, showing a concentrated championship peak rather than isolated breakthroughs.

1971-1973 was his strongest three-year stretch

Across those three seasons he reached six major quarterfinal-or-better results: French Open champion in 1971, US Open finalist in 1971, Wimbledon semifinalist in 1972, then French Open finalist, Wimbledon champion, and US Open finalist in 1973. That is the densest elite run in the table.

His best Wimbledon and US Open runs came in consecutive years

Wimbledon peaked with a semifinal in 1972 and a title in 1973, while the US Open peaked with finals in 1971 and 1973. Those results show his top-level performances at those two events clustered tightly in the early 1970s.

Late-career decline is clear after age 31

From age 31 onward, his results never again reached the quarterfinal stage: R32 at the 1977 US Open, R32 at the 1978 French Open, and only R64 or R128 finishes from 1978 through 1981. The drop is especially sharp compared with his 25- to 29-year-old peak.

His career is unusually strong in historical comparisons

Among men in the Open Era he ranks #22 of 2307, and among players with overlapping careers he is #11 of 681. He is also #2 of 32 from Czechoslovakia and #1 of 25 born in 1946, placing him near the top of every comparison group shown.
