Dellin Betances, Yankees; Zach Britton, Orioles; Wade Davis, Royals; Will Harris, Astros; Andrew Miller, Yankees; Glen Perkins, Twins Perkins, Britton and Miller (disabled list) are the only closers, and Britton (23 of 24 saves, 1.82 ERA) could be swapped out for Huston Street of the Angels (0.891 WHIP, 23 of 26 saves) without much of a quibble. But Perkins hasn’t blown a save in 26 tries. Harris, discarded by Arizona, has been the surprise key to the Astros’ bullpen, which has a 2.63 ERA that trails only Kansas City in the AL. He has a 0.96 ERA and a 0.696 WHIP. Betances has compiled a 1.11 ERA and 66 strikeouts in 402/3 innings.
