A few tips from my side:
Chela to beat Martin @ 1,32 (H2H is 3-1)
O. Rochus to beat Volandri @ 1.3
Gaudio to beat Robredo @ 1,67 (H2H is 3-2 (2-0 on hardcourt
Mathieu to beat Haas @ 1,98 (Mathieu played great in Canada while Tommy has only played 2 matches since Wimbledon. H2H is 1-0. So it´s worth a shot).
