Chafin came on in relief Wednesday against Miami and struck out the only batter he faced, J.T. Realmuto.
This was a bounce-back appearance for Chafin, who walked two batters in Tuesday's appearance and suffered the loss. The lefty has primarily been used as a middle reliever this season and proven effective in short-inning situations. Chafin is the only left-hander seeing consistent usage out of the Arizona bullpen and he should continue getting opportunities despite a 4.22 ERA.
