The Cubs have signed Scott Baker, who missed all of the 2012 season following elbow surgery.

"I truly believe if you put the work in and prepare yourself for every start, that's the best you can do," Baker said. "Once you go out there and you are fully prepared then it's about executing pitches. If I can execute pitches then I can be a very productive pitcher and give this team a chance to win some ballgames. In saying that, I think we're going to have a lot of fun. I'm excited working with the coaching staff and medical staff.

"It's a big season for me and the organization. I look forward to giving the team a chance to win."

Theo Epstein acknowledged the risk in signing a pitcher coming off Tommy John surgery.
