The turning point of this fall's epic Boston Red Sox comeback in the American League Championship Series took place not in the ninth inning of Game 4—when Dave Roberts stole second base, putting the tying run in scoring position—but two innings earlier, when Roberts made his way from the dugout through the team's clubhouse to the weight room, where the Red Sox video command center is arrayed against the end wall.
There, Roberts asked Billy Broadbent, who handles video systems for the Red Sox, to queue up footage of New York Yankees reliever Mariano Rivera pitching from the stretch with a man on first base. Two innings later, Roberts put to good use what he had learned from the team's massive digital archive of opposing pitchers.
