EDGE Analysis
Morales made two relief appearances during his time with the major-league club, and he picked up his first career save in Friday's win over the Dodgers. Although he tossed three scoreless frames over his two outings, the 22-year-old will head back to the minors, where he's posted a 0.55 ERA and 0.75 WHIP in 16.1 innings over nine appearances this year.
