Good idea to get a thread like this going, as the time to talk about and exploit the market is when it is at its most ineffecient. Having said that, given the current quality of posts and demographics of the MLB forum, and a sensical thread like this may fall by the wayside here.
Tommorrows card does look decent. Betting Sunday's games on the overnight in general can be very advantageous and/or dangerous due to teh simple notion that there are more backups in the lineup on Sundays compared to any given day. This is where research and anticapation of the projected lineups can really pick off value off the open.
I am going to have to disagree with you on your DBacks assesment. I had the Dbacks med/large yesterday and had the Mets small today. Tommorrow I will probably have the Mets small/medium. I think the market is finally starting to correctly value Garland and their bearish sentiment on Pelfrey may be a tad overboard.
I had a position on the White Sox in all three of the first games of the series. Typically if a team is undervalued 3 straight games against another team, they are likely to be undervalued again. But here I agree with you. In fact, I see small value on the Yankees, and I think the market will bid them up more up to the close.
I was somewhat suprised to see oddsmakers put the Cubs/Marlins at even money on the open given the way Nolasco has been playing, the way the Marlins have been playing, and the way Dempster looked in his first start coming off the DL. I valued the game at Marlins -111/Cubs +111, and prior to the lines coming out, was anticpating I was going to have a bet on the Cubs.
Best of luck.
