Eric Davis -- Did I Party with Charlie Sheen? HELL YES!!!

Question: Darryl Strawberry and Charlie Sheen walk into a party in the '80s ... who does the first line of primo Colombian coke??

Turns out, Eric Davis can probably answer that question ... 'cause the former MLB superstar (who was BFFs with Darryl) tells TMZ Sports the Warlock was a member of his party crew back in the day.

Sheen is a die-hard Reds fan ... and Davis says Charlie used to hang out and practice with the squad during his run with Cincinnati.
