Peak came in 1975 with his only quarterfinal

Masters’ best Grand Slam result was a quarterfinal at the 1975 Australian Open, when he was 24. That season also included a Wimbledon R32 and a US Open R128, making 1975 his strongest Slam year in the table.

His best stretch was concentrated in 1973-1975

Across those three seasons he reached at least the round of 64 in every Slam entry shown, and he produced his only R16 in 1973 plus his only quarterfinal in 1975. The sequence marks the clear high point of his Slam career.

Australian Open was his most productive major

He played the Australian Open 10 times and reached his best results there: one quarterfinal, one R16, one R32, and three R64 finishes. No other Slam in the data matches that depth of progression.

Wimbledon was his second-best stage

Wimbledon produced his only R16 outside the Australian Open, plus two R32 finishes and four R64 results. That is a stronger profile than his French Open and US Open records, which never went beyond R32 and R64 respectively.

Late-career results faded after age 27

From age 27 onward, his finishes were mostly R64 or worse: R64 at Wimbledon and the Australian Open in 1978, R32 at the 1979 Australian Open, and only R64/R128 results in 1980. The lone exception was the 1978 Wimbledon R16 at age 27.
