I have been using my site for a while for college football and since I watch a lot of tennis I have been checking out the wta wagers

all the matches, wta - tokyo

right now for example are over/under 21 1/2 except radwanska's upcoming match so it appears.

Total Points
Williams O- 21 1/2
Halep U- 21 1/2


It seems to me that a easy risk would be Under 21 1/2 on all MLs above say 250 or 300 (for easy heavy favorite matchs) and on a few select pk or ML -110 to -140 games it would be over.

But definiitely much easier to predict the unders. You can look at Head 2 Head for any of the matches a see a trend. Any thoughts or strategies.

i.e. any Azarenka - Serena match without a doubt over 21,22 or 23
