Gonzo, I've met the guy several times and I seem to recall him saying he wasn't much of a player so I'm surprised by all those titles. You have to be a little wary about "facts" reported online if you don't know the source.
I could introduce you if you ever make it out to the events. I see him at some of the top flight tennis tournaments typically berating pros and fans alike to disclose their views concerning Rios. He seems to get sad if you don't know who Rios is but he quickly perks up if you appear at all interested in learning. I always allow him a few Rios stories except I require one or two beers in me at the time.
I think he knows more about Rios as a tennis player than Rios does.
