Insights

Peak came immediately in the Open Era

Okker’s only Grand Slam final came in 1968 at the US Open, when he was 24. That same early Open Era stretch also produced semifinal runs at the 1969 French Open and the 1971 Australian Open and US Open.

Wimbledon was his most productive major

Across the data, Wimbledon produced his deepest and most frequent late-career runs: a final in 1979, a semifinal in 1978, quarterfinals in 1975 and 1969, plus fourth-round finishes in 1977, 1974, 1971 and 1970. No other Slam matches that volume of high-end results.

His best results clustered between ages 24 and 35

Okker reached every one of his listed semifinal-or-better results from age 24 through 35, starting with the 1968 US Open final and ending with the 1979 Wimbledon quarterfinal. After age 35, his Grand Slam results dropped to R128 at the 1980 US Open and 1981 Wimbledon.

French Open success was concentrated in a short window

He reached the French Open quarterfinals in 1967 and 1973, and the semifinals in 1969. Outside that span, the only French Open result shown is a first-round exit in 1978, making Roland Garros his most sharply peaked major.

His Open Era record was strong but top-heavy

Of his 31 Grand Slam tournaments, 30 came in the Open Era, where he compiled all 83 match wins and every listed final, semifinal and quarterfinal except the 1967 Amateur Era quarterfinal. The overall record was 83-31, a 73% win rate.
