Nadal is a bad match up for Monaco (of course, just about everyone is a bad match-up to Nadal on clay). But I saw the last few results from Monaco vs Nadal on clay and he has been clobbered all times. I think the score will be something like: 6-3 6-2 6-1 to Nadal.
The Gasquet/Murray match (if we can see it from TV) will be interesting. IF Gasquet can continue his good play - he has a shot against Murray (whereas Monaco has NO shot whatsoever against Nadal). But which match are they showing?
