» August 23, 1989: Rick Dempsey homers off Dennis Martinez in the top of the 22nd inning to break up a scoreless tie and give the Dodgers a 1–0 win over the Expos. The game features one thumbing -- the umps toss the Expos mascot Youppi in the 11th for annoying Tommy Lasorda -- and he then returns in the 13th wearing pajamas. He carries a pillow and sleeps on the home dugout roof, where the umps have restricted him. In the 16th, Larry Walker apparently scores the game-winner, but the Dodgers appeal -- with two umps in the tunnel -- and get it. Eddie Murray in the 18th moves the 2B ump and slams a drive that Walker makes a phantom catch off the padding in RF. Fans stand for three "seventh-inning stretches" during the major-league record (in time, and for a 1–0 game) six hours: 14 minute game. Other club records are set and several ML records are noted: most innings (22) without a walk by the Expos tops the Pirates (who used one pitcher) against the Giants, July 17, 1914.
