Ever since the club dealt superstar slugger Paul Goldschmidt to the Cardinals prior to the 2019 season, the Diamondbacks have been relying on Christian Walker to pick up the slack at first base. In his first three seasons as a regular, Walker was somewhat uneven as he posted roughly league average numbers with the bat overall (103 wRC+) thanks to decent but unimpressive strikeout (24.1%) and walk (9.6%) rates that combined with only average power. While Walker posted above average defensive marks during that time, that wasn’t enough to make him an impact player at a bat-first position like first base, leaving him to generate just 4.1 fWAR over his first three seasons after taking over for Goldschmidt.
