The Cardinals are asking Shelby Miller to control the run game more efficiently, according to MLB.com.
Miller has been fantastic this season, but opposing base-runners are seven for eight off him. The Cardinals recently timed Miller with a stopwatch, and found he was too slow during his windup. Miller admitted he has been making some mental mistakes, and vowed to take care of the issue.
Miller will work on his "hold" times during bullpen sessions, which will allow him to figure out the most effective ways for him to cut down on his time to the plate. Miller's next start will come May 20 against the Padres.
