I'd be wary about betting against baltimore much this year. They have some pretty good talent. Combine that with the unpredictable nature of their games, and this could easily swing baltimore's way.
Yanks, under appears good, but the yanks bat's have been hot lately (fueled by swisher sweets), and joba wasn't as sharp as the yanks hoped in the last couple spring starts. I know spring is usually meaningless, but those last couple games were played with a "act like this is the regular season" mentality by the yanks pitchers.
I like:
Yanks (-1) - meche is good, but yanks bats are hot
Cubs (-1) - suppan is mediocre, dempster will get it done
Reds (-1) - harang is old reliable, snell is mediocre
ATL (-1.5) - olsen won't hold his own, value - 100 point diff. vs. ML
CWS/MIN Under 9.5 - buerhle sim. to washburn who held MIN down, blackburn will limit sox (sim. pitching type as halladay)
SEA/OAK Under 8.0 - OAK won't get far vs. bedard (didn't do well against lefty saunders, bedard not much diff.), cahill has sinker action on fastball which might fool seattle enough to keep them under 4 runs.
