Allen, 31, has had a rough go of things since he hit a wall in the 2018 season. His effort to bounce back last year with the Angels fell short and he’s now struggling to earn his way back to the majors.
The 25-year-old King is now in a position to clamor for his first call to the majors. He still hasn’t appeared above the High-A level, but was quite effective there last year. Over 71 frames, the former tenth-round pick turned in a 2.03 ERA with 7.9 K/9 and 1.4 BB/9.
