If Del Potro hadn't choked his last couple times on the big stage, I might say he'd belong in the top 5...but man he can really go away quickly in the big stage. Hard to argue too much with the 5 men besides it not having Murray (how is he not on the list?) Schynder probably doesn't deserve to be on the list for her level of play now though. I'd replace her with...ummm...Bepa maybe? Vika if it's just based on 2009/
