Stolen Signs is back. Harry and Kendall talk about the slow offseason, collusion and ideas on how to change the economics of baseball. After a short break (14:05) they discuss new research by Duke University that looks into neurological and motor skills and how they translate to baseball production, a new smart baseball that can provide some pitch tracking and tease some new work by the stats team at Baseball Prospectus. To wrap up (32:00), a look into the state of pitching and try to talk about what an inning(s) eater is and also what an ace is.

This week Harry and Kendall talk to Jarrett Seidler from the Baseball Prospectus Prospects team about the cyclical nature of baseball in general, and analytics specifically.
Harry and Kendall also take a closer look at how pitchers end up in their eventual roles and examine their route to get there. For this exercise they looked at pitchers with a debut season of > 20 IP as a reliever, and fewer starter innings than reliever innings in that year and then went on to log > 75 IP as a starter in a subsequent season, with fewer reliever than starting innings. Check out the spreadsheet.
