I gave it a try and I bet $5 on each of:
Tipsarevic bt Huta Galung 1.38 Lost
Przysiezny bt De Voest 1.67 Lost
Lopez bt Dancevic 1.43 Lost
Brown bt Van Der Merwe 1.71 Lost
Kavcic bt Berrer 2.1 Lost
Bellucci bt Machado 2 sets to 0 1.8 Lost
Robredo bt Mello 1.3 Won
That leaves me $28.50 down from betting $35.
Never thought it would be this hard.
You have no idea my friend.
