<P> The Pawtucket Red Sox and the Rochester Red Wings, two teams from the Triple - A International League, played the longest game in professional baseball history . It lasted 33 innings, with 8 hours and 25 minutes of playing time . 32 innings were played April 18 / 19, 1981, at McCoy Stadium in Pawtucket, Rhode Island and the final 33rd inning was played June 23, 1981 . Pawtucket won the game, 3--2 . </P> <P> The game began on Saturday, April 18, 1981 at 8: 25 p.m., after a delay of about 30 minutes due to problems with stadium lights, with 1,740 in attendance . It continued through the night and into Easter morning . Although most leagues have a curfew rule that would have suspended the game--the International League's activates at 12: 50 a.m.--the rule book that the home plate umpire Dennis Cregg had did not contain one . After Pawtucket's Russ Laribee's sacrifice fly drove in Chico Walker in the bottom of the ninth inning and tied the game at one run each, the teams continued playing . </P>
