MLB did something in 2008 that looked fairly unremarkable. The league set a new record for strikeout rate, bumping just a hair above the record of 17.3% after having spent the last decade bouncing back and forth within the boundaries of a single percentage point.
The 17.5% K-rate was not dramatically higher than the previous record from 2001. But it was the start of something big. Baseball broke this record again in 2009—and 2010, and 2011, and every year since, with no signs of stopping. It’s looked like an unrelenting march across the Land of Balls in Play to the Sea of Three True Outcomes.
