Michael Wacha will start on three days' rest with the bullpen ready to carry innings if needed. But the Cardinals are confident that Wacha can continue his recent success, including a seven-inning, two-run effort against the Reds on Saturday. STL is 45-25 at home and I'll back them here tonight as SF has struggled vs NL Central teams this year and the Cardinals have been RED HOT their past 30 games.
