There was another case of fans behaving badly in San Francisco yesterday (Thursday). Following the Giants loss to their cross-Bay rival Oakland A's, a fight broke out between rival fans leaving one woman unconscious and in the hospital with serious injuries.

Police say the 30-year-old A's fan was trying to break up a fight between her boyfriend and two other men outside of AT&T Park when she got punched in the face, fell back and slammed her head on the sidewalk. Witnesses say the suspects fled in a car and police are now searching for them. (CBS San Francisco
