Shipley recalled, Barrett optioned to Triple-A

PITTSBURGH -- The D-backs' reliever shuffle continued Sunday as they recalled right-hander Braden Shipley from Triple-A Reno and optioned reliever Jake Barrett back to Reno.
Barrett had been called up Thursday to provide an extra arm in the bullpen after the team optioned starter Matt Koch to Reno.
Barrett pitched one-third of an inning Thursday and an inning Saturday. With rain in the forecast for Sunday, the D-backs wanted to have a fresh arm in the bullpen in case there's a lengthy rain delay early that would force starter Clay Buchholz to not be able to continue.
Shipley, the team's first-round pick in the 2013 Draft, has been a starter throughout his professional career, until last month when the team shifted him to the Reno bullpen because it felt it gave him a better chance of contributing more this season.
The D-backs will need to make another roster move with the pitching staff Monday, when Shelby Miller is scheduled to be activated from the 60-day disabled list to start against the Marlins.
