GLENDALE, Ariz. -- Matt Thornton, who had a temporary setback Tuesday with discomfort in the back of his left elbow and triceps area, threw all of his pitches in a 35-pitch bullpen on Sunday morning and came away feeling "great.'' He remains on his normal throwing schedule.

"Aside from being numb from the cold and wind ... everything felt good,'' Thornton said. "Got my work in till I felt like I was starting to fatigue and shut it down.''

Thornton is scheduled to pitch in a game for the first time on March 5, as originally planned.
