Carlos Marmol has been placed on the restricted list at Triple-A Louisville after leaving the club without permission. It's not clear why Marmol left or how long he plans to be gone, but obviously it's not ideal as he tries to make it back to the majors. The reliever was signed to a minor league deal two weeks ago after being released by the Marlins. Marmol has allowed three runs while walking six over 3 2/3 frames at Louisville.
