Arizona Diamondbacks Top 56 Prospects: 2025 Farm System Rankings

The Arizona Diamondbacks don’t have a farm system full of future MVP favorites. What they do have, though, is arguably just as valuable these days: a deep, layered pipeline with role players, high-upside projects, and enough pitching depth to keep a contender afloat for a while.

This article digs into why Arizona’s prospect base is built more on organizational depth than headline-grabbing star power. How does that fit into the modern MLB scene? Let’s get into it.

Arizona’s Farm System: Depth Over Star Power

The Diamondbacks’ front office has really leaned into a philosophy that values volume, versatility, and developmental upside. They’re not chasing just a couple of “can’t-miss” prospects. With over 120 players in their prospect mix, Arizona wants to win the numbers game.

They aren’t pinning their hopes on one or two elite blue-chippers. Instead, they’re stacking the system with players who have a legitimate shot to break through, even if none look like surefire superstars right now.

A Broad, Balanced Talent Pipeline

Arizona’s system has a healthy balance of bats and arms. They focus on projectable tools rather than polished, MLB-ready skills. It takes more developmental work, but the upside is there if the coaching staff gets it right.

This approach matches a league-wide trend. Teams that collect a wide variety of potential contributors often end up with more big-league value than those that rely on just one or two elite prospects to carry all the weight.

International Talent: High Upside in the Making

The international market has become a key artery for Arizona’s prospect flow. The Diamondbacks are betting on athleticism and long-term projection, even if that means taking on more risk up front.

Two names really highlight that strategy and could make a difference in a few years.

Mayki De La Rosa and Victor Santana Headline the International Group

Mayki De La Rosa stands out as a classic high-upside international signing. He’s a projectable power athlete whose physical tools just pop. Not a finished product, but his size, strength, and athleticism give him a shot at becoming a real middle-of-the-order threat if the hit tool develops.

Victor Santana brings something different. He’s more of a contact-oriented hitter with a solid foundation at the plate. If his bat matures and he adds even a bit of power, he could climb quickly and end up as a solid everyday guy or maybe a high-end role player.

Pitching Depth: Starters, Relievers, and Risk Management

On the mound, Arizona isn’t rolling out obvious ace-level arms. Instead, they’re building a rotation of potential mid-rotation starters, backed by a bullpen pipeline with some real velocity and variety.

The organization seems pretty comfortable betting on volume and development to create value with their pitchers.

Mid-Rotation Starters and Diverging Reliever Profiles

Among the starters, Kyle Ayers and Adonys Perez look like potential mid-rotation options. They’re not frontline aces at the moment, but they offer that steady, innings-eating value every competitive team craves. If either one sharpens their command or secondary pitches, their ceilings could jump.

The relief corps is more polarized. Arizona’s relievers usually fall into two groups:

Philip Abner and Tayler Montiel are among the more promising bullpen arms. They offer enough stuff and strike-throwing ability to project as legit big-league relievers. And let’s be honest, in today’s game, finding just a couple of these guys can really pay off.

Hitting Prospects: Strength, Power, and Developmental Questions

On the position-player side, the Diamondbacks have put together a mix of size, strength, and raw power. There are plenty of questions about contact rates and where these players fit defensively, though. This is where Arizona’s player development staff faces its biggest test.

The club’s broader strategy seems obvious: prioritize bats within certain value tiers and let development decide who sticks and who doesn’t.

Nathan Hall, Ruben Santana, and Upper-Level Power Bats

Nathan Hall looks the part, with big-league size and pop. The raw ingredients are there for a productive hitter, and if he refines his approach, he could carve out a solid role at the top level.

Ruben Santana brings potentially plus power to the table. His challenge is making more contact and improving discipline at the plate. If he cuts down on swing-and-miss, his power could push him into a meaningful big-league role.

At the upper levels, Ivan Melendez is your classic modern power bat: massive raw power, but real questions about hitting consistency and defense. If the bat plays every day, Arizona will find a way to get his power in the lineup. If not, he still has a path as a matchup-driven role player or bench bat with pop.

A System Built on Role Players and Breakout Potential

What really stands out about the Diamondbacks’ farm system is its depth and variety. There’s no one superstar prospect here, no obvious crown jewel.

The organization doesn’t have a player graded at 55+ Future Value. Still, that doesn’t make the system weak—far from it, honestly.

Arizona’s focused on finding and developing all kinds of role players and potential contributors. They’ve given themselves a bunch of different ways to win.

Maybe an international hitter suddenly finds some power. Or a reliever finally locks in his command. Sometimes a mid-rotation starter just clicks and takes off. Any of those breakouts could totally change how people see this system.
