Interesting draw for Marin. In the first round he faces Santoro, who deserves respect, but Marin should still beat him. Second round wildcard Tomic or a qualifier, also very beatable for a player like Marin, third round probably the same match as Chennai final, against Wawrinka, so Marin beat him a week ago, why wouldn't he do it again? 4th round Del Potro... Last year at the USO Marin was winning and then just stopped, hopefully he won't do it again, and he wins this time, it would get him to QF where he'd face Roddick/Berdych/Gonzalez, they're all players Marin can beat but it would already be great if he gets there. I don't want to even talk about what would happen if he gets further.
To sum it up, I expect a very good tournament for Marin, IMO he reaches 4th round at least.
