Schramek's a LH hitter who supposedly has a strong arm. BA listed him #20 at his position. The Reds must have seen something they liked in him.
As for Gruler, wild guess here, but I'm thinking the Reds took the path I advised, namely, if you like Gruler and Kazmir equally, then pick the cheaper one.
