EDGE Analysis

Otero will be replaced on the roster by Ryan Merritt, who is expected to start Game 2. After posting a shiny 1.53 ERA and 0.91 WHIP through 70.2 innings last season, Otero has turned in a less impressive 3.02 ERA and 1.24 WHIP through 50.2 innings this season. He should return to a middle relief role upon his activation.
