Not long
The game was called due to darkness. The longest game in MLB history was 26 innings between the Boston Braves (now Atlanta Braves) and Brooklyn Robins (now Los Angeles Dodgers) on May 1, 1920. The game ended in a 1-1 tie because of darkness as there were no lights in the stadium to be used to illuminate the field. Lights were not used in an MLB stadium until 1935.
