16 games as closer. 7 saves, 1 blown save. 13-3 record during those 16 games. 21 k's, 3 bb's. 25 ground balls, 18 fly balls.
I can't find the babip stat for that period, but I'd take those numbers from a closer any day of the week in our ballpark.
This is where BABIP can be a flawed stat IMO. A ball put in play against a soft-tossing lefty would seem to have a better chance of "finding a hole" than a ball put in play against a flamethrower. The problem with BABIP is that it pretends that the odds are the same once the ball is put into play no matter which pitcher you are facing. I would love to see the numbers over a long period of time, but I would not be surprised at all to learn that Sean Marshall's BABIP is consistently higher than that of Aroldis Chapman's. Once it becomes "consistent" it's no longer "bad luck."
