Bullpen routine is completely different from starter routine. He's coming off of a major injury. The best thing that can happen to him this year is that he gets locked in his routine and gets his strength built back up with an eye towards the long term. Having him spend a chunk of the year not knowing if he's throwing that day, the next day, or whenever isn't useful in his buildup towards starting. Santana pitched out of the pen initially as a way to hide him on the roster. Then he spent the better part of the next two years relieving as well. That was his routine, and then he worked over to starting. Minus a few rehab outings, Gibson has been starting exclusively his whole career, and should remain on his starter's routine. Period. His 130, 150, or however many innings he throws this year aren't make or break for the Twins' 2013 fortunes, but keeping him healthy and progressing towards a full workload next year and beyond is certainly going to be a much bigger factor in their successes in those seasons.
