EDGE Analysis

The 23-year-old was designated for assignment to clear a roster spot for catcher Austin Wynns. Duran, acquired from the Dodgers on April 2, made just one appearance in the majors, allowing three runs in one-third of an inning. His struggles have continued at Triple-A Las Vegas, where he's posted an 8.00 ERA and 1.96 WHIP over 27 innings.
