Don't know about series prices, but if you go to covers they have past results going back to 1999.....
Yankees swept the Braves....
first game score 4-1 at even
second game 6-5 at +110
third game 7-2 at -145
fourth game 4-1 at -150
I'm just taking a guess that the series price couldn't have been too high given that the odds on the first two games were so low......that's merely a guess.....I'm thinking had they been prohibitive favorites to win the series then the odds for the first games would have been near -200.....
Maybe someone elese could chime in with a better source or some information about the series price......
Thanks for at least that much info. If my calculations are correct, the first two games were in Atlanta, which might have accounted for the lines being that low. Wish I could find out that Series price...
