Diamondbacks designated LHP Philip Abner for assignment.

Abner has struggled in eight appearances with the Diamondbacks this season, posting a 6.28 ERA, 1.53 WHIP and a 6/8 K/BB ratio across 14 1/3 innings of work. It feels like there’s a decent chance he may pass through waivers unclaimed. Dennis Santana was added to the Diamondbacks’ bullpen in a corresponding move on Sunday.
