Cardinals pitcher Michael Wacha is working to refine his curveball, according to the St. Louis Post-Dispatch.
Wacha mainly relied on two pitches last season, a fastball and changeup. Both are considered strong options, but most starters are encouraged to throw three pitches. Wacha has been encouraged with the pitch's development. "It's coming along nicely," Wacha said. "I've definitely got some more work to do. I'm definitely working on it in bullpens and side sessions."
As of right now, the team also has no plans to limit Wacha's innings. Pitching coach Derek Lilliquist said Wacha could be a 200 inning guy this season.
Wacha posted a 2.78 ERA in 64 2/3 innings during the regular season before going on a spectacular run during the postseason.
