The pace of the game has slowed as a result, with an average of 5 minutes and 47 seconds between balls put in play. These statistics are presented in a fascinating article, well worth a read, by Brian Costs and Jared Diamond in today’s WSJ: The Downside of Baseball’s Data Revolution–Long Games, Less Action. Last night’s wild card game between the Twins and Yankees was a case in point.
