I like PITT here with a pitcher that has solid revenge and is on a bounce-back that comes off one of his shakiest starts of the year and you combine it with a Cardinals pitcher that comes off one of his best starts and Pitt played well vs Phillies taking 2 of 3 games.
Tonight's starter Keller is having one of his best years, if not his best after 4 solid years of pitching, he has a mid 3 ERA. This is the same pitcher that dominated the Mets, Reds, Twins, Braves and others prior to this so we'll back the Pirates tonight!
