I went 1-1 +0.26 units yesterday.
Astros +210
Pros: The Astros have done well this season versus the Mets. Their starter, Randy Wolf, has been very successful in his career versus them. He is opposing Oliver Perez, who has struggled earlier this month against them. He gave up 4 earned runs over 6 innings. The Astros seem to have lefty's numbers this year. At this big of a dog, you can't afford not to take the Stros.
Cons: Perez has been great since the All Star Break.
Pirates +270
Pros: CC Sabathia is a very good pitcher, but there is no way he can win every game. He gets a considerable amount of chalk each time he pitches at home for the Brew Crew. +270 is a lot of chalk when the opposing pitcher has been very impressive. Maholm has been great this month as well as the entire season. He also has good numbers versus the Brew this year. You are laying +270 on a 3.64 ERA and 1.23 WHIP. I think that is pretty much the definition of value.
Cons: CC is undefeated in Milwaukee.
