EDGE Analysis

Guerra was recently designated for assignment by the Marlins on Aug. 22, but will be re-added to the 40-man roster and placed on the active roster heading into this weekend's series with Philadelphia. Over four appearances with the club this year, Guerra has posted a 6.35 ERA and 1.59 WHIP in 5.2 innings, and figures to serve as added depth out of the bullpen.
