In the 7th inning of a 2013 game between the Houston Astros and Los Angeles Angels of Anaheim, Culbreth, acting as the crew chief for the game, made an incorrect call for which he later received a two-game suspension and a fine. Houston manager Bo Porter made a pitching change, and Angels manager Mike Scioscia called for a pinch-hitter. Porter attempted to make a second pitching change and Scioscia immediately contested it. After discussing the call with his umpiring crew, Culbreth allowed the pitching change, violating the MLB rule 3.05(b). He did not serve his suspension immediately, and he continued working regular games in the weeks following the incident.
