text_A: In July 1983, while the Royals were headed for a second-place finish behind the Chicago White Sox another chapter in the team's rivalry with the New York Yankees occurred. In what has come to be known as "the Pine Tar Incident", umpires discovered forbidden placement of pine tar (more than 18 inches up the handle) on third baseman George Brett's bat after he had hit a two-run home run off Gossage that put the Royals up 5–4 in the top of the 9th. After Yankee Manager Billy Martin came out of the dugout to talk to home plate umpire Tim McClelland, McClelland and the other umpires mulled over the bat (measuring it over home plate, touching it, etc.). McClelland then pointed to Brett in the dugout and gave the "out" sign, disallowing the home run. Enraged, Brett stormed out of the dugout toward McClelland and Martin, and McClelland ejected Brett. The homer was later reinstated by AL President Lee MacPhail, and the Royals won the game after it was resumed several weeks later.
text_B: Would George Brett have good reason to complain about the umpires who examined his bat?
DON'T KNOW.
