With the young umpire's absence while A.J. Johnson donned the plate umpire equipment creating a two-person crew of 3B Umpire McClelland and 1B Umpire Jim Joyce, the senior crew chief opted to move behind the pitcher in order to call pitches, an acceptable albeit rarely seen umpiring mechanic. Lack of immediately accessible plate gear also may have played a role.
Buckminster, who was struck on the left wrist, was seen exiting the field while grasping his mask with the right, not left hand. After the game, it was revealed that the errant pitch indeed fractured Buckminster's left hand.
