“Even when we were down big early, I could tell that we were fighting today,” starter Lucas Giolito said. This is the environment of a postseason game: back and forth, we were down 5-0 with two losses already. Manager Alex Cora hesitated in bestowing this one result with too much significance. This was the first time in eight chances this season that the Red Sox (55-49) won an extra-innings game on the road.
