Some of my favorite words in pro sports are "pitchers and catchers report..." and it's coming up. I don't know the exact dates for either Chicago team but I think it must be sometime in the upcoming week.
So for the Sox, they have some solid pitchers coming. Their candidates for their rotation are John Danks, Gavin Floyd, Edwin Jackson, Mark Buehrle, and Jake Peavy, if he's ready. Chris Sale has apparently been working all winter to get a chance to start. So the Sox appear to be set with some combination of those six. Their bullpen is in a little more flux. They did sign the guy from the Twins (can't recall his name) and they still have Thornton and Sergio Santos, but Bobby Jenks is gone and their closer role is a little up in the air.
On the north side, the Cubs will go to camp with Zambrano and Matt Garza at the top of their rotation. Ryan Dempster slots in next, with Randy Wells, Carlos Silva and a couple of youngsters out of the group of arms that gave them starts last year competing for the back of the rotation. Their bullpen is a little more settled, with Marmol returning in his role as closer and many of the same names as last year.
Pierzynski and Soto return to backstop their respective team's rotation.
