So only slams on red clay (FO) and cement (USO post 1977) will be

considered.

So in Open Era we have

1. Borg (6 on red clay) and Lendl (3 on red clay , 3 on cement) = 6

slams

3. Sampras (5 on cement) = 5 slams

4. Mcenroe (4 on cement). Wilander (3 on red clay, 1 on cement) = 4

slams

6. Connors (3 on cement), Agassi (1 on clay, 2 on cement), Kuerten (3

on clay ) = 3 slams

9. Edberg (2 on cement), Courier (2 on clay), Bruguer (2 on clay)

So looks like Borg and Lendl are joint GOATS

1. Graf (6 on clay, 5 on cement) = 11 slams

2. Evert (7 on clay, 3 on cement) = 10 slams

3. Navratilova (2 on clay, 4 on cement) = 6 slams

4. Seles (3 on clay, 2 on cement) = 5 slams

5. Sanchez (3 on clay, 1 on cement) = 4 slams

6. Serena (1 on clay, 2 on cement) , Henin (2 on clay, 1 on cement) = 3

slams

8. Venus (2 on cement), Austin (2 on cement), Mandlikova (1 on clay, 1

on cement) = 2 slams

So looks like Graf is the GOAT

Again proves my theory, Borg, Lendl and Graf are the GOATS, no

questions asked.
