Doc Halladay was limited to just 25 starts because of injuries and wasn't as effective as we've come to expect on the mound when he was healthy last season.

Lower back issues forced him to the disabled list for a time. He finished 2012 with an 11-8 record and a 4.49 ERA, which was his highest since he finished the 2000 season with a 10.64 ERA.

"I'm not here to predict anything, but I feel good," Halladay said. "If I can feel the way I feel right now and maintain it and get stronger through the course of Spring Training like you normally do, I feel very confident that I can be effective."

He has a program in place to prevent those problems from coming back, which he said involves more rotational and functional exercises.

"When [the back] stiffened up on me, it put the pressure on my shoulder," Halladay said. "It changes everything. It really does. You're trying to throw with your arm instead of using your lower half and your core. To me, that leads to a lot of issues in the upper body. I feel like we've addressed those, we've alleviated them. Along with all that, we've done some arm care stuff differently this year, starting about midseason we started changing some stuff. So I feel good all the way around."
