Former Oakland A's star and San Francisco Giants innings eater Barro Zito was on a television program titled "The Masked Singer" on Wednesday night, where he was evidently "unmasked" as "The Rhino" after his elimination from the program. At this point, nothing was amiss. But then Zito appeared on "The Masked Singer: After The Mask," "The Masked Singer" aftershow, and did something no Giants fan could ever forgive.
