The Cubs placed right-handed reliever Zach Rosscup on the Disabled List last night due to shoulder stiffness.
Rosscup, 27, has been mediocre for the Cubs. His ERA sits at 4.3 this season, and his nERD is ranked 260th for pitchers, at 0.71. Brian Schlitter, a 29-year-old with a 5.40 career ERA in the majors, is expected to take his spot.
