Wacha, 22, didn't allow a run in 13 2/3 innings against the Dodgers in the NLCS and for his efforts was named NLCS MVP. Against the Pirates in Game 4 of the the NLDS, Wacha took a no-hitter into the eighth inning.
After returning to the Cardinals' rotation in early September, he posted a 1.72 ERA over the balance of the regular season -- a span that includes one rough start in Coors Field. For the 2013 regular season as a whole, Wacha pitched to a 2.78 ERA, 131 ERA+, 1.10 WHIP and 3.42 K/BB in 64 2/3 innings at the big-league level.
The real question for Matheny and the Cardinals, though, is who will start Games 3 and 4 back in St. Louis. Joe Kelly, Lance Lynn and Shelby Miller are all in the mix.
