Just to let you know, Verkerk won that final set tie-break 7-1, and it wasn't Ljubicic's injury that hindered him. At 4-1 down, with two points on his serve, he dumped one low forehand into the net and then sent a backhand into the tramlines, almost as if he was deliberately throwing away the match.
Still though, good for Martin - I now hope he can face the Niemster in the final!
