Mets + Red Sox @2,65 8 units
That's risky really considering that Dice-K is usually wobbly at the start of the season and Blanton is quite a reliable pitcher for the As.
I'd much rather look for the same value in AngelsVsTwins at over 9 which looks a good bet with 2 rather fragile pitchers. Usually hitters get away with some cheap hits at the start of the season. Pitchers tend to need time to bed in... .
