EDGE Analysis

During his brief stint with the Padres over the last week, Kirkman made one disastrous relief appearance, giving up four runs on six hits across 1.1 innings. With the removal of the 40-man roster spot, the Padres may have signaled that the southpaw has his work cut out for him to return to the majors this season.
