Jake Peavy had a light throwing session Tuesday morning that left him more optimistic about his rotator cuff tendinitis. The White Sox right-hander threw on a back field for about 5-6 minutes at 30-40 feet and reported no significant discomfort. "I felt quite a bit better than I did a few days ago so I was excited that things are certainly calming down," Peavy said. "The biggest thing is that we were [previously] doing things [natural], just trying to do everything by the book." Peavy made four consecutive spring starts, but reported shoulder soreness after each of them. He threw 83 pitches in a Saturday start and then the soreness was finally diagnosed as tendinitis.
