Amazing Cuban Base-brawl

I'm trying to piece together what we're looking at here from the Spanish description on YouTube, and as far as I can tell it's a wicked brawl at the José Antonio Huelga Stadium in Sancti Spíritus, Cuba. Aaaaand... that's about all I've got. It's a pretty fantastic brawl, even though the best part-- the batter chasing the pitcher into the outfield with a bat-- happens right off the top. Enjoy!
