The return for Denard Span, Meyer may be one of the most frustrating Twins prospects. Touted a front line ace, Meyer is now 25 and has yet to see major league action. 2014 ended with injury for Meyer, but at this point, the command issues need to be refined at the highest level. His 10.4 K/9 ratio is something the Twins so badly need.
