yanks -1.5 was 79-21 last year(2010 season including playoffs). so out of their 100 total wins last year, 79% of those wins were won by at least 2 runs. so if they win, almost 80% of the time they win by at least 2 runs. i think there is very good value in NEVER betting the yankees as high favorites, and just taking them at -1.5 every time you play them. most of the time that will be + money. instead of taking them -175 for a moneyline, like they usually are, take them at -1.5 runline and get +115 on it, or something around there.
