G.O.A.T.
You're glossing over the fact that this occurred after 2001. A far greater achievement was Agassi winning in 1992 by beating Forget, McEnroe and then Goran on fast grass, without type 3 balls and without poly. As far as achievements by baseliners at Wimbledon go, that's second only to Borg.
Yes but McEnroe was not in his prime and Goran was only getting there and Agassi’s game was quite suitable on fast grass, so that was not highly unexpected. Once Sampras peaked, of course, Agassi had no chance. He was lucky he got the Wimbledon out of the way otherwise he would have been short of that.
