I have noticed that everytime Roger has tried to pull off a tweener or has pulled it off, he has not one that slam.
Case: last year, he did it against Djokovic, lost to Del Potro
Case #2: Australian Open against Safin, lost the semis when match point.
Case #3: against Henman, he almost did it and then lost the final to Rafa at Wimbledon (if I am not mistaken, please correct me).
Case #4: we are yet to see if he wins this years US Open
I have not seen other top players actually pulling off Tweeners. Andy Murray has done some crazy shots, but he does not have a slam.
Do you guys remember any top player who has pulled off a tweener and then gone on to win that slam?
He hit a tweener against Henman at the U.S. Open, not Wimbledon. Henman was retired the year Nadal beat Federer at Wimbledon.
