With a new baseball season on the horizon, an old problem has surfaced for Cubs pitcher Kerry Wood. The Chicago Tribune reported on Monday that Wood has been sidelined by a shoulder problem and is headed for a stint on the disabled list for the 11th time in his career. One day after giving up three runs on three hits in one inning, Woods was examined by a Cubs team physician after complaining of discomfort in his right pitching shoulder, according to the Tribune.
