Anderson (back) has officially landed on the disabled list, Patrick Mooney of CSN Chicago reports.

EDGE Analysis

The righty was only able to record a single out in his start Saturday before departing with the injury, and a DL stint was forecasted later in the day, so this news doesn't come as a surprise. Anderson will be eligible to return as soon as May 16, while fellow pitcher Justin Grimm was called up from Triple-A Iowa on Sunday in a corresponding move.
