Defensive Woes: Can the D-Backs Turn it Around?

The 2025 season was a tough one for the D-Backs, and their defense was a major culprit. It's no secret that the team's defensive performance left much to be desired, with commentators often highlighting the errors that drove the manager to despair. But here's where it gets interesting: despite the visible struggles, the D-Backs' defense wasn't abysmal according to some metrics.

FanGraph's defensive rating placed them 11th in the majors, while Baseball Reference's defensive runs saved ranked them 24th. However, these positions mark a significant decline from the previous year when they were top-tier. This decline, combined with other factors, contributed to their less-than-stellar performance.

Roster Adjustments

The team's defensive woes can be partly attributed to the first base position. Josh Naylor, who replaced Christian Walker, is a solid player but doesn't match Walker's exceptional 2024 performance. Interestingly, Walker's skills took a hit last year, bringing him and Naylor to similar defensive levels. With Naylor now in Seattle, the D-Backs brought in Carlos Santana, an upgrade defensively over Naylor, especially considering his Gold Glove-worthy season just two years ago.

At third base, the team has a defensive stalwart in Nolan Arenado, whose prowess contrasts with Eugenio Suarez's history of defensive struggles. Suarez's defensive shortcomings are more noticeable when his offensive output is lower, like his .189/.255/.428 slash line. The front office's strategy is clear: sacrifice some offense for defensive stability, relying on other players to make up for the lost firepower.

Individual Player Development

While roster changes are essential, the team's defense can also benefit from the growth of its existing players. Geraldo Perdomo, for instance, had a breakout season last year, but there's still room for improvement as he settles into his role. Gabriel Moreno, a defensive powerhouse, faces a different challenge. Despite his skills, Moreno has been plagued by injuries, affecting his playing time. His durability is key to the team's success, as a healthy Moreno can be a game-changer.


The D-Backs' defense is a complex issue, and opinions may vary. Was the defense truly as bad as it seemed, or were the struggles exaggerated? Are the roster changes enough to turn things around, or is more needed? And what about the team's strategy of trading offense for defense? Is it a gamble that will pay off, or a risky move? Share your thoughts in the comments below, especially if you have a different take on how the D-Backs can improve their defensive game.
