One question has fascinated me for a while now: How much have modern closers changed the game? I mean, sure, we know they have changed many things SURROUNDING the game in obvious ways. Closers have helped change the salary structure of the game. They have changed the way managers direct a game. They have given us indelible memories -- the stomping of Al Hrabosky, the high heat of Goose Gossage, the mustache of Rollie Fingers, the Dan Quisenberry sinker ball, the unhittable pitches of Craig Kimbrel, the wonder of Mariano.My question is just a little bit different and more focused on results: How much more often do baseball teams win games they lead going into the ninth inning now that closers rule the ninth inning?
