No matter what the final score is, you made the right call. I'm surprised the line was 8 and not 8.5 with two explosive offenses involved (Even with Hambone and Beltre out), but more importantly, as far as the pitchers are concerned, I can't really think of anyone off the top of my head that has had a bigger second-half drop-off than CJ Wilson, so it'd be awfully tough for him to just suddenly flip the switch against one of the best lineups in the game. And as good as Derek Holland has been lately, which is truly excellent, he's always had problems against the Angels.
As I write this, it's 0-0 in the top of the third, but you got plenty of time, and offenses that can go for a big inning at any given point against two sometimes combustible pitchers (Especially Wilson in the second half of 2012). GL
