Here's my experiment. They let you parlay the same game for the teams and one player vs player total bases. So if you think it will be a pitcher duel you can take the under for the total and parlay it with the under for the total bases. I know one doesn't garentee the other but I think it improves it quite drastically.
So yesterday was PPD
Today I have two:
St Louis /Cincinati Under 7.5
Holliday / Votto Total bases Under 3.5
25$/47.25$
Toronto / Tampa Bay Over 7.5
Encarnacion/ Longoria Total Bases Over 3.5
25$/38.75$
