Neither Petszner, Sock nor Stepanek were easy right?
Stepanek is great player. And he still can be a problem, but in another format of play. 5 sets - too much for 34 years old guy.
If you follow Petzschner for years, you know that even Paire is mental focused giant in comparison with Phil. He can play very well, yep, but on big points you should play direct and easy for taking your chances and Phil just can hit with any thought, then depressed and play is over. I like this guy, but he is 10-th level choker.
About Sock I have written already.
Almagro wasn`t that
lucky on 1st week like Nole, for example, but he got cool draw. It could be far harder.
