Rays starter James Shields is making some changes in hopes that he'll have a bounce-back season in 2011. Shields went 13-15 with a 5.18 ERA last year. "You look back at last year and forget about it -- that's over with," he said. "You obviously try to make adjustments to fix what you might have done wrong and try to implement those adjustments in Spring Training so that you can start the season off strong. I had great offseason workouts and my body feels tremendous now. I just need to move forward. I feel really good." Picking apart his mechanics, Shields pinpointed that falling off the mound during his delivery and landing on the outside of his plant foot contributed to the ball arriving high and fat. Thus, he incorporated some different things during his offseason workouts to address his mechanics. "I implemented a little more of the biomechanics of my pitching and just really worked on the strength of my core and the stability of my legs," Shields said. "I think that's going to help out a lot."
