Relatively unprecedented. From MLB:
Umpire Fieldin Culbreth, the crew chief in Thursday night’s game between the Los Angeles Angels of Anaheim and the Houston Astros at Minute Maid Park in Houston, has received a two-game suspension and a fine for the misapplication of Official Baseball Rule 3.05(b) in the top of the seventh inning, Major League Baseball announced today.
The other members of Culbreth’s crew – Brian O’Nora, Bill Welke and Adrian Johnson – have received fines stemming from the same sequence of events … Culbreth’s two-game suspension will be served at a date to be determined by the Office of the Commissioner.
We’ve heard that sometimes umpires get disciplined, but it’s rarely if ever publicized like this. Good for baseball for doing the right thing.
