Major League Baseball has fired umpire Pat Hoberg ... after it was determined he shared a sportsbook account with a friend who bet on baseball games.
The league announced Monday afternoon Hoberg -- who called a perfect game in the 2022 World Series -- failed to "uphold the integrity of the game" and deleted messages that were key to an investigation into the matter.
It all started back in February 2024 ... when a sports betting operator notified MLB the 38-year-old opened an account under his own name with his pro poker player buddy.
