In this clip, a fight breaks out between both human-garbage A's and Giants fans after an A's fan apparently touches/pours beer on female Giants fan. This besmirching of a dame then prompted one of the male Giants fans in the now wet girl's group to respond with fighting words, which then prompted this unfortunate and all-too-common physical melee. Who's side are we on? The side that isn't going shirtless at a baseball game. So tacky.

This fight comes on the heels of Giants fan Bryan Stow getting attacked at a Dodgers game, and a fight inside Candlestick Park during a 2011 Niners-Raiders game that spilled into the parking lot and resulted in two people getting shot. Play nice, people.
