Are you even aware that there is difference playing 30 stroke rallies in the 5th set on clay vs world fittest baseline grinder and one-two punch tennis on grass ?! Tsonga was never clay hero,and he probably never will,being built like heavyweight boxer.Clay is his worst surface, few years back he even didnt have ANY clay wins whatsoever.
Grass on the other hand is whole different matter. If it goes into fifth, I dont expect Murray to have any big fitness advantage over Jo, then it all depends how players mind works and who blinks first on his serve.
But no need to argue here further. After few hours we know what happened on Centre Court, who came through and who failed to do so.
Good point indeed, but I have my doubts (albeit not as much anymore
Good luck and have a great weekend everyone!
