Dugan, you have me confussed. How can betting a parlay with the Yanks to both the over and the under, make sense?
One of those wagers has to lose, and if the Yanks lose, both bets are toast.
So, since you need the Yanks to win the game to win either of the parlays, you would be better served to bet both amounts on the Yankees to win.
Books don't give money away too often.
