The division reports debuted last year. The goal of this article series is to provide a quick overview of all dynasty-relevant information from each division. Each team has multiple levels each containing plenty of impactful prospects which can feel impossible to keep up with. This article series, which will be updated once per month, will help dynasty managers stay up to date on performances, injuries, promotions, and more. New this season is the inclusion of tiers in the rankings. Next to their rank, each prospect is assigned a tier. The tier range is 1-5.
- Tier 1: A potential difference-making dynasty prospect. Somebody who would rank in the top-20ish prospects for dynasty baseball
- Tier 2: A still very good dynasty prospect who holds plenty of value. This prospect would typically rank in the 21-75 range
- Tier 3: A mid-tier prospect who could be valuable but has questions and concerns present in his profile ranking in the 76-150 range
- Tier 4: A prospect who is worth knowing, but is reserved for deeper leagues. This prospect would rank 151-250
- Tier 5: The rest of the prospects fall into Tier 5
The 2025 season is winding down. The fantasy baseball playoffs are in full swing, and fall is in the air. Now is the time that most fantasy baseball nuts tend to lose focus. Unfortunately, dynasty managers are not afforded that opportunity. Staying up to date on the latest prospect news is essential to taking your team to the next level. Dynasty leagues never sleep. This article updates the Arizona Diamondbacks prospect rankings while providing news and notes on the latest promotions and performances.
Notable Prospect Performances:
- Ryan Waldschmidt continues to show just how underrated he is. For those following this series or my work, Waldschmidt has been a favorite of mine throughout the season. Already ranking as a tier-one prospect, he has been sensational to end the year. Since August 7, Waldschmidt is slashing .414/.522/.658 with more walks than strikeouts. He has five-category upside and remains an elite dynasty asset.
- Ivan Melendez is utilizing a really aggressive approach at the plate. The question with Melendez has always been his hit tool. On the surface, Melendez has played well since being promoted to Triple-A. He is batting .293 with two home runs in 23 games. However, under the surface, there are still concerns. Melendez is swinging 58.3% of the time with a chase rate of 39.3%. His contact skills have been surprisingly solid, but there remains a significant risk here.
- David Hagaman has looked sharp since joining the organization. Hagaman was the Rangers’ fourth-round pick in 2024 and has looked excellent since joining Arizona’s organization. In five starts, he owns a 35.5% strikeout rate, a 5.3% walk rate, and a 3.15 ERA. He pitches entirely from the stretch, but has a plus fastball and slider combination that could make him a sneaky breakout pick for 2026.
Notable Prospect Promotions and News:
- Daniel Eagen was finally promoted to Double-A. Eagen was dominant in High-A for the majority of the season, but the team was extremely slow in promoting him to Double-A. Well, he is now there and has made three starts. Eagen’s control has taken a step back since his promotion, but his dynasty stock is certainly on the rise.
- Kayson Cunningham is getting his feet wet in Low-A. Cunningham got a taste of professional baseball for 11 games in Low-A. The team’s first-round pick from 2025 hit .255 with zero home runs in the 11 games he played in. Cunnigham’s fantasy upside is uncertain and dependent on how his power develops. For now, he ranks as a tier-four prospect outside of the top 150.
- Junior Franco was promoted from High-A to Double-A. Franco signed with Arizona back in 2019 out of the Dominican Republic and is more of a peripheral prospect at this point. In 73 games at High-A, Franco hit .300 with seven homers and 10 stolen bases. The 5’9″ outfielder just turned 23 years old and is unlikely to ever become a fantasy-relevant player.
