When crosstown rivals square off in interleague play, you can bet your sweet ass there will be some donnybrooks in the stands.

This weekend’s series between the San Francisco Giants and Oakland A’s didn’t disappoint.

For context, we turn, as we always should, to the YouTube uploader’s description.

A’s fan touches/pours beer on female Giants fan, male Giants fan in her group walk him outside and talk, fighting quickly breaks out.

Succinct prose.

And a pretty good throwdown.
