Alvarado was recalled from Double-A Montgomery on Wednesday.

EDGE Analysis

Prior to the 21-year-old's callup, the Rays were rolling without a left-hander in their bullpen. Alvarado will fill that void as he heads to the majors Wednesday, looking to take the 2.38 ERA and 11.4 K/9 he posted in 11.1 innings with the Biscuits into his big-league debut.
