Welcome to the second annual edition of the RW23 hitter projections. RW23 — creatively named after Rickie Weeks — was created in 2017 with the help of Mike Podhorzer and his book, “Projecting X 2.0: How to Forecast Baseball Player Performance.”

Below you’ll find the RW23 hitter projections for the 2018 Milwaukee Brewers’ roster as of March 25, along with the Steamer and ZiPS projection systems for comparison. In its debut season, RW23’s hitter projections went toe-to-toe with Steamer, while solidly beating ZiPS.
