Looking at the stats, 'Results' is basically the most popular sub-page on the website so I'm reluctant to mess around with it, I certainly wouldn't replace it with 'Titles'.
Why do you think that is?
Because I would imagine it may be people looking up "andy murray result" or similar and hoping for the latest update by going to that page, but they just get each tournaments last match......?
I would think a list of his titles might be nice though, perhaps in his profile page....?
Titles: Masters Series 1 (2008), Masters series 2 ( ), San Jose (06,07..... etc etc)
