Boxberger, 30, has struggled recently. He blew Sunday’s save chance against the Braves, yielding three runs while recording only one out. He has given up runs in three of four appearances to start the month of September, causing his ERA to balloon to 4.41.
Boxberger had been solid prior to September, ending August with a 3.45 ERA, 31 saves in 37 chances, and a 67/24 K/BB ratio in 47 innings.
Yoshihisa Hirano, Brad Ziegler, Archie Bradley, and Andrew Chafin could all see some save opportunities down the stretch. The D-Backs entered Monday’s action 2.5 games out of first place in the NL West and three games out of the second Wild Card slot, so this change will certainly have an impact on whether or not the D-Backs reach the postseason and in what fashion.
