When Carson Kelly arrived from the Cardinals in the trade for Paul Goldschmidt, the team was hopeful they had found their everyday catcher of the future. Kelly had understandably been blocked in St. Louis by future Hall of Famer Yadier Molina, but had no such competition in Arizona. 2019 saw him stake a solid claim to the position, being worth 1.7 bWAR in 111 games. However, since then it has very much been a case of one step forward and one back for Kelly. The COVID-shortened 2020 was a disaster at the plate for Carson, his OPS dropping to 73, and his walk-rate dropping below 5%.
