The Reds have designated outfielder Derrick Robinson for assignment in order to clear a 40-man roster spot for utility man Skip Schumaker, according to John Fay of the Cincinnati Enquirer (Twitter link).
Robinson, 26, batted .255/.322/.323 without a homer in 216 plate appearances for the the Reds in 2013 — his first taste of Major League action. Though he's posted some gaudy stolen base totals and owns 317 swipes in his minor league career, he was just 4-for-9 in that department with the Reds. He was solid defensively, appearing in both left and center field. UZR/150 pegged him at +5.4 runs in the outfield, while Defensive Runs saved had him at +6 despire his limited playing time (395 1/3 innings).
