Reader Osiris flagged this bad news by way of Paul Sullivan in the Tribune:
The Cubs placed Rich Harden on the 15-day disabled list with a back strain on Friday, and inserted Randy Wells into the rotation for Saturday's game.
This will allow the Cubs to activate Carlos Zambrano without having to make another roster move, i.e., demote Wells. Harden felt "a twinge" when he pitched last Sunday against the Astros.
You may vomit as you see fit.
