Tracking my Australian Open plays, mainly going to be 2-4 player parlays. Tracking record on parlay plays not units, you get an idea how much u could win. I usually bet between 20-50 on each one depending on how confident I am. Smaller parlays the more I would bet.
Parlay 1
Youhzny-Nadal over 34.5
Brown-Dmitrov over 33
Seppi-Isomin over 40.5
Those are the most likely matches that sound like they will go 4-5 sets...Seppi and Isomin seem to go 5 everytime they play a grand slam.
