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 of home plate umpire Dennis Cregg 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>
