All top 4 got a slam this year. Ever happened before???
So each of the top 4 players took a slam this year
1 Federer -Wimby
2 Djokovic - AO
3 Murray - USO
4 Nadal - RG
Pretty interesting, is it good for tennis? I'd have preferred Murray to retire slamless but I guess it made for an interesting situation. Has this ever happened before?
