A fan at a minor league baseball game got doused with his own beer ... after a foul ball hit his drink straight into his face -- and the entire, hilarious scene was all captured on camera!
The funny incident went down during Springfield's game against the Northwest Arkansas Nationals on Saturday ... when Cardinals second baseman Chandler Redmond was up to bat against pitcher Anthony Veneziano.
Redmond took a couple pitches -- and then fouled off a ball that somehow ricocheted into a can that was placed near a screen behind home plate.
