On July 24, 1983, the Kansas City Royals played the New York Yankees.
The Royals were down 4-3 in the top of the ninth. George Brett came to the plate and hit a two-run homer to give the Royals the lead.
Immediately after Brett returned to the dugout, Yankees manager Billy Martin requested the umpires to inspect Brett’s bat for an excessive amount of pine tar.
The umpires decided Brett did had too much pine tar on his bat and called him out of the game.
Brett was not pleased.
After his home run was nullified, Brett was the third out in the top of the ninth, and the game ended with the Yankees winning 4-3.
Pine tar is applied to the handles of baseball bats to improve a batter's grip. The Official MLB Rules state pine tar may be applied for up to 18 inches on a bat. If the pine tar extends past 18 inches the umpire can order the batter to use a different bat.
