I think I'm about as fit as I've been the last 10 years. As far as my fitness level for playing a couple sets of doubles, this isn't about fitness. This is going to be about -- you know, luck is going to have something to do with it, mentally sort of how I handle it, how Jonas handles it, how my opponents handle it. Everyone is going to come into this with a different level of pressure, feeling they have to prove themselves in different ways. From that standpoint, the way I see it, it's more mental than anything else. I could see myself doing doubles in five years. I hardly feel like that's a big issue.  -   John McEnroe     Quotes
