Jared Shuster: Everything you need to know

The Cardinals outrighted Shuster to Triple-A Memphis on Monday. Shuster has the ability to decline the outright assignment and elect free agency, but he made the choice to stick around in the organization last month and could do so again. The left-hander has made four relief appearances this season for St. Louis, yielding three runs (two earned) with a 2:3 K:BB over 7.2 frames.

The Cardinals designated Shuster for assignment Saturday, Jeff Jones of the Belleville News-Democrat reports. The 27-year-old will end up as the roster casualty necessary to make room for Matt Pushard's (knee) return from the injured list. Shuster has performed well during his time with St. Louis, allowing just two earned runs through 7.2 innings. However, his 7.25 ERA at Triple-A over the past two seasons could dissuade other teams from picking him up off waivers.

The Cardinals selected Shuster's contract from Triple-A Memphis on Friday. Shuster was removed from the 40-man roster in mid-April after allowing two runs with a 1:2 K:BB over 3.2 innings during a brief stint with the Cardinals. He's now back with the big club to provide length in the bullpen.
