I see a value on Malisse.
Xavier played semi on 2011 and on 2010, he has a remarkable 46w 25l on grass since 1996; on the other hand, Viktor has already tested Halle's grass, defeating Becker (not so difficult) but crashing against Berdych. I don't think he has great skills for grass, so I will try Malisse to win @ 1.78 (BF)
PS: my personal ratings says Malisse 108,92pts - Troicki 94,05pts
GL to everybody
