We have exact data on the spin of a baseball as it leaves the pitchers hand. We have sprint speed, launch angle, hit probability, and on and on. The list of numbers is almost endless. I used the Rotochamp.com projected lineups for my comparison, with some slight edits when it comes to the use of Steamer. The St. Louis Cardinals didn’t require alterations, but other teams did.
For example, Steamer projects Francisco Liriano to throw 30 innings, but Rotochamp has him listed as a starter. I substituted in Mitch Keller instead, who is projected to throw 92 innings.
