Diamondbacks designated LHP Mike Zagurski for assignment.
The left-hander gets the boot to make room on the active roster for Bryan Shaw, who was recalled from Triple-A Reno in a corresponding move. Zagurski struggled mightily in his 32 appearances with the D’Backs this season, posting a horrifying 6.18 ERA, 1.48 WHIP and 26/14 K/BB ratio over 27 2/3 innings.
