Naile was recalled by the Cardinals on Thursday.
While with Triple-A Memphis this year, Naile has recorded a 3.48 ERA and 1.36 WHIP over 67.1 frames out of the bullpen. He has made two brief stints in the majors, throwing just six innings over five appearances this season and has allowed just two hits in that time. He figures to provide depth to what is already a very solid Cardinals bullpen.
