CLEARWATER, Fla. – Beneath the concrete seating bowl of Spectrum Field, there is a dimly lit corridor that leads to a golden rectangle of sunshine. Step through those doors over these next couple of weeks and you'll hear the surest sign that spring has sprung: an arrhythmic volley of whiplike cracks and dull leather thuds echoing across a vast expanse of green. In the distance, on a long mound of compacted sand, a red line of pitchers will aim and fire as they dutifully complete the bullpen workouts they need to rebuild the strength in their arms after a winter of rest.
