DAVE DAVIES, HOST:
This is FRESH AIR. I'm Dave Davies in for Terry Gross, who's off this week. Spring's here, and baseball's back. It's a comforting tradition for a lot of us, but big-league baseball evolves over time. And our guest, New York Times national baseball writer Tyler Kepner, keeps track of that. He notes, for example, that for the first time ever last year there were more strikeouts than hits in the majors, which he thinks is connected to the widely shared complaint that the game moves too slowly and takes too long.
