The game was rescheduled for Sunday at Yankee Stadium. Game 7, if necessary, was rescheduled for Monday in New York.
New York leads the series 3-2 and needs one victory to clinch its 40th league pennant and reach the World Series for the first time since 2003.
Rain has been falling off and on in New York since late Friday. A steady drizzle, with occasional spurts of heavy downpour, kept the tarp on the field all afternoon. The game was called by Major League Baseball nearly 2 hours before the scheduled start.
Joe Saunders had been slated to start for Los Angeles against fellow left-hander Andy Pettitte.
