October 26th, 2017 | 1 hr 2 mins
baseball, pitching, world series
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.
