At this rate, the relentless Boston Red Sox might eliminate the New York Yankees sooner than anyone thought.

Jason Bay drove in four runs, Dustin Pedroia hit a grand slam and Boston routed the listless Yankees 11-3 on Wednesday night, putting an emphatic dent in New York's dwindling playoff chances.

"I never write the Yankees off until the season's over and the standings are set," Pedroia said. "They've been around too long and been in the playoffs for such a long time that we're definitely not counting them out."
