Federer rivalries...10+ encounters

Let's say a rivalry means 10+ encounters with at least 2 victories on both sides:

vs Hewitt 14-7
vs Roddick 18-2
vs Nadal 7-13
vs Nalbandian 10-8
vs Kiefer 12-3
vs Ljubicic 12-3
vs Henman 7-6
vs Safin 10-2
vs Ferrero 9-3
vs Agassi 8-3
vs Djokovic 7-4
vs Santoro 9-2
vs Haas 8-2

vs Murray 2-6 [not (yet) 10+ encounters]

Are you aware if there's anybody against whom Federer played more than 21 matches (Hewitt's case) ?

Are you aware of other rivalries ?

I wonder if Henman would consider that record one of his biggest career prizes. It's quite impressive, especially since two of those wins came in 2003/2004.

If Hneman could do that, makes you wonder how Federer would have faired in the 90s.

Henman originated the "beat Roger and make him cry" maneuver.

the only real rivalries in that list were between Fed and both Nalbandian and Hewitt, plus Haas to some extent, only those matchups had a sense of rivalry in them.

and currently Nadal, of course.

vs Gonzalez 12-1

vs Santoro 9-2

I guess you're missing the great encounters Fed and Safin had in 2004-2005
