Introduction
The Arizona Diamondbacks struggled defensively in the 2025 season, ranking between 11th and 24th in various metrics, a significant drop from their previous year’s performance. To address this, they replaced Josh Naylor with Carlos Santana at first base for improved defense and acquired Nolan Arenado for third base, trading offensive power for defensive strength. Key players like Geraldo Perdomo and Gabriel Moreno must also develop further, especially given Moreno’s injury history. The team’s success hinges on their ability to enhance defensive capabilities while maintaining offensive productivity from younger players.
