Career Surface Slam

Only 6 players have achieved career Surface slam-winning Majors on 3 surfaces
Aparr from Big 3 the other 3 are:
1.Connors- 4 Grass titles/1974 Australian, Wimbledon and Us Open,1982 Wimbledon/,3 Hard/1978,1982,1983 US Open/,1 Clay/1976 US Open/
2.Wilander-3 clay/1982,1985,1988 French Open/,2 Grass/1983 and 1984 Australian open/,2 Hard/1988 Australian and US Open/and
3.Agassi-6 hard/1995,2000,2001,2003 Australian open,1994 and 1999 US Open/,1 Grass/1992 Wimbledon/,1 clay/1999 French Open/


I think Evert might be tops in this regard - majors on clay, grass, and hard. With the added distinction of majors on AO grass and Wimbledon grass (but not USO grass). Plus majors on Roland Garros red clay as well as USO green clay.
