All hell broke loose in a minor league baseball game Tuesday night ... with players throwing violent haymakers at each other during an insane brawl that was all captured on video.
The melee went down in the 8th inning of a game between Chicago Cubs and San Diego Padres minor leaguers in South Bend, Ind.
The Cubs' affiliate, the South Bend Cubs, was taking on the Padres' affiliate, the Fort Wayne TinCaps ... when the ending of the game turned ugly in a hurry.
Video from the broadcast shows all of the action initially began in the 7th inning .
