Baseball and beer go together like peanut butter and jelly -- unless the game is going down at a little league field ... and "Desperate Housewives" star Doug Savant learned that lesson the hard way.
TMZ has learned Savant was recently suspended by his kid's L.A. little league -- after a concerned parent noticed the actor secretly downing a brew out of a paper cup while in the stands.
We're told the parent in question confronted Doug -- calling him out for violating park rules -- and the poor guy had to face the Board of Directors soon after the incident.
Savant -- who's actually president of the damn league -- was suspended for an entire weekend. He couldn't be reached for comment.
