At Toronto, George Brett is robbed of an apparent triple by his teammate Mike Armstrong. Brett hits a liner down the RF line that Armstrong, sitting in the bullpen, thinks is foul and retrieves. Umpire Bill Kunkel decides to send U.L. Washington, who scored on the play, back to third base, and Brett is sent to second. Brett has a homer off Jim Clancy but Kansas City eventually loses, 8 – 2.
