The Cardinals have designated Bryan Augenstein for assignment, reports B.J. Rains of FoxSportsMidwest.com (on Twitter). The move frees up a roster spot for P.J. Walters.
Augenstein, 25 next week, had been claimed off waivers from the Diamondbacks during the offseason. He appeared in five games for St. Louis, all in relief, and allowed seven runs in 5 2/3 innings. He struck out six, but walked three (all intentional) and allowed 11 hits. In 12 2/3 innings in the minors, Augenstein struck out 13 but allowed 11 runs.
