Major League Baseball has announced that the rule covering pitching changes was not applied correctly by the umpiring crew in the seventh inning of Thursday's game between the Houston Astros and Los Angeles Angels.
The Angels played the game under protest before going on to win 6-5 after scoring three times in the eighth.
The dispute came with two outs in the seventh when Astros reliever Wesley Wright ran onto the mound and threw several warm-up pitches before rookie manager Bo Porter raced onto the field between the mound and home plate to stop him from throwing more.
Hector Ambriz soon jogged out of the bullpen and onto the mound, and Wright headed to the dugout.
Angels manager Mike Scioscia ran onto the field and argued that Ambriz shouldn't be able to enter the game because Wright did not face a batter.
