BOSTON — Just to show off at this point, Boston Red Sox manager Alex Cora should send Ben Affleck or one of the several Wahlbergs out there to pinch hit. Maybe he could have someone from the grounds crew toss a couple of innings of middle relief, or dig up Tex Hughson and see if the old cadaver’s got one more hitter in him. At this point, Cora should go to Vegas and hit 18, every time. He should buy a ticket in every lottery in America. He should wander America’s beaches looking for Spanish gold. He should bet on blind greyhounds, three-legged thoroughbreds, and chickens that can play tic-tac-toe.
