With the Cardinals' rotation banged up, fans are clamoring for starting pitcher prospect Michael Wacha, who is dominating at Triple-A Memphis, to be promoted to the majors. However, the Cardinals are taking a cautious approach with the 2012 first-round pick.
"Everybody is focused on the Wacha 'clock,'" general manager John Mozeliak told the St. Louis Post-Dispatch, referring to the nickname for big-league service time. "The clock is something that is well-documented and it’s something that we think about."
Mozeliak warned of the dangers of rushing Wacha and having to deal with Stephen Strasburg-esque issues worrying about overstressing a developing arm. Wacha, who is 4-0 with a 1.89 ERA in eight starts for Memphis, has just 68 2/3 pro innings under his belt. For perspective on how the Cardinals have handled prospects in the past who they viewed as ace material, rookie Shelby Miller tossed 383 2/3 innings in the minors before joining the Cardinals' rotation and Adam Wainwright had 793 innings in the minors (the latter split between the Cardinals and Braves organizations).
