AFL Notebook: Final Thoughts on the D-backs’ 2025 Fall League Class and More

A final sweep through the notes, observations, and development clues from Arizona’s 2025 Fall League group and other players.

SCOTTSDALE — With the Arizona Fall League coming to a close on Friday, I’d thought I’d take this opportunity to give my final thoughts. 2025 marked the most aggressive year that I covered the Fall League, covering 25+ games and events.

The hope was to use all the free time I had to stay in the game as long as possible, build a portfolio, and establish a rapport with some of the Diamondbacks’ prospects.

D-backs Prospect and Coach Thoughts

The best prospect from the D-backs’ contingent is RHP David Hagaman. He features a four-pitch mix (4-seamer, curveball, slider, and changeup). His slider is his best pitch of the arsenal. Due to the gyro shape (0” iVB, 2” glove-side), it has more utility against left-handed hitters than a typical right-handed slider would.

Hagaman has the upside of a No. 3 starter due to a deep mix and the potential for an above-average fastball and a plus slider. In terms of raw upside in the system, I’d only put 2025 first-rounder Patrick Forbes ahead of him.
