EDGE Analysis

Smith originally landed on the injured list in late March due to elbow inflammation before being transferred to the 60-day IL on Tuesday. His surgery is expected to keep him sidelined for approximately 6-to-8 weeks, lining him up to return sometime in late May or early June. Adrian Del Castillo and Jose Fernandez have been in the mix for starts at DH while Smith has been out.
