The Cubs activated Williams (abdomen) from the 10-day IL on Tuesday, Meghan Montemurro of the Chicago Tribune reports.

EDGE Analysis

The righty returns to the Cubs after lasting five scoreless innings Friday in his second rehab outing with Triple-A Iowa. Williams' 5.36 ERA this season is nothing pretty, and Alec Mills has been decent of late as the fifth starter, so it's possible Williams shifts to the bullpen.
