Yeah , that was shocking but he is getting up there in age...
I also beleive he was playing injured , if you watch closely his matches at Wimby his upper leg was wrapped in tape and I also beleive he had a bad back as his serve wasent there today
I still think he has 2-3 slams left in him but that's about it
I dont think he'll ever regain the # 1 seed again either to break Pete's 286 week at number 1
kinda sucks as he's sitting at 285
