Borg won over 100 tournaments in his career by age 25.
Incidentally Bill Tilden can be argued to be ahead of anyone and of course Ken Rosewall.
pc1, I would still rank Borg ahead of Nadal.
As you cite Rosewall: I have forgotten in my Rosewall achievements that Muscles keeps another fantastic record: He reached 36 consecutive SFs at majors from Wimbledon 1954 to French Open 1968. Of course I concede that the pro majors had only 8 -16 participants. But still awesome.
