The successful introduction of youth was the overriding theme for the 2023 D-Backs. Inevitably, that successful introduction would result in any number of roster casualties from previous holdovers as the franchise’s rebuild finally came to fruition.

Zach Davies’ decline was not quite as bombastic, but it ended in the same result as 2/5 of the 2022 rotation failed to end the season with the team in 2023.
