Baseball thoughts for a Tuesday morning: -- It's time for the Giants to end the Barry Zito charadeand cut him loose over the winter. Do it for his sake, for cryingout loud.

Notthat he'd suddenly become a world-beater, but can you imagineZito's sense of relief if he donned a new uniform next spring?
