I think Federer is playing amazing right now but Hewitt will be a battle with Federer pulling thru.
Grosjean should have enough experiece to take out Mayer.
Henman should beat Ancic, but everyone knows how Henman has trouble carrying Britain on his shoulders.
Finally Roddick should beat Schalken, but he has not played well at all.
Federer should take out Grosjean in a match similar to Hewitt.
Henman should be able to chip and charge is way to the finals by picking on the weak Roddick backhand and keeping the pressure on.
Federer should rip Henman apart.
