For those of you asking why Mike Matheny decided to go with Michael Wacha over Shelby Miller as a starter against the Pirates in the Divisional Series, the answer is in the numbers:  Shelby Miller made four starts against the Pirates this season and went 0-4 with an ERA of 5.31. Wacha has pitched well down the stretch including a two-hitter over seven innings on September 8th in a big win at Busch Stadium.
