Insights

Two French Open titles, both at age 32–33

Parker’s best Amateur Era results include two championships, and both came at the French Open: in 1948 at age 32 and again in 1949 at age 33. Those are his only title finishes in the supplied Grand Slam rows.

US Open was his most frequent stage, with four straight appearances

Six of his eight Grand Slam results were at the US Open, spanning 1946, 1947, 1948, 1949, and then 1968. That makes the US Open the clear center of his Grand Slam record, including his lone Open Era appearance.

Peak run came in 1947 with a US Open final

His deepest result outside the French Open titles was the 1947 US Open final at age 31. The surrounding US Open results show a progression from quarterfinal in 1946 to final in 1947, then semifinal in 1949.

Late-career Open Era return ended immediately

After a 19-year gap from 1949 to 1968, Parker returned only once in the Open Era and exited in the US Open round of 64 at age 52. His Open Era best result is therefore just R64, far below his Amateur Era peak.

All eight Grand Slam results fit into a narrow age window

Every listed result came between ages 30 and 52, with seven of the eight occurring from age 30 through 33. That cluster shows his entire Amateur Era Grand Slam peak was compressed into four seasons, 1946-1949.
