I think no matter how much it isn't said, I still think that incident with the young player has drained Marin a little bit emotionally. It seems after the tipsy match in washington he's hit a wall physically, and he was absolutely thrashed by nalby on saturday. He needs at least a week or two off before the open or he will be upset within the first 2 rounds.
Troicki is gradually coming up, beating better players.
I do think its strange that Troicki and Tipsarevic so often just happen to be pitted against each other in the first two rounds such as now at Toronto. Either that or they are up against top 10 players, while other players in their ranking are playing opponents around their range or less.
But I guess I'm just being paranoid. The draw never ever gets manipulated, right?
