2026 MLB Draft Preview: Hunter Dietz, The Potential Power Pitcher

As the 2026 MLB Draft approaches, the Philadelphia Phillies are once again considering a focus on pitching, potentially eyeing Hunter Dietz, a left-handed pitcher from Arkansas. Baseball America has projected this move, prompting a closer look at what the Phillies might gain if they decide to bolster their roster with another arm. Standing at an imposing 6’6″ and weighing 235 pounds, Dietz’s journey has been anything but straightforward.

Despite having pitched less than two innings in college before this season, Dietz had a challenging summer in Cape Cod, where he struggled through 11 innings in what were essentially rehab starts following a near two-year hiatus from the mound. However, his performance this year has shown significant promise, boasting an impressive 13.8 strikeouts per nine innings and a 3.3 walks per nine innings over 85 and two-thirds innings. While concerns about his command linger, he has demonstrated the potential to achieve and maintain average control.

Dietz’s injury history raises red flags, having missed time during his freshman year due to a stress fracture in his elbow and an ulna bone injury during recovery. Fortunately, he has avoided tendon injuries, but these setbacks are closely related to the ulnar collateral ligament (UCL), which could be a cause for concern. Nevertheless, with his robust build and if he can stay healthy, Dietz has the potential to develop into a solid mid-rotation pitcher or even a number two starter.

His arsenal includes a mid-90s four-seam fastball that can reach up to 98 mph, characterized by an over-the-top delivery that generates notable backspin and carry. However, his max-effort mechanics have contributed to command issues with this pitch. Additionally, he features an upper 70s to low 80s curveball that he has shown good control over, which might become a second plus pitch. Recently, he has also developed a slider/cutter in the upper 80s, which has shown promise and complements his fastball effectively. His changeup, while still a work in progress, will be crucial in determining whether he becomes a reliable starter or a high-leverage bullpen option.

In video footage, Dietz appears to throw 95 mph fastballs with ease, although his short stride and rotational delivery raise questions about his mechanics. While hitters often have linear or rotational swings, applying these terms to pitchers is less common, yet it resonates with Dietz’s pitching style. His injury history adds to the intrigue; extending his stride might help him utilize his height more effectively and improve command.

The Phillies have previously selected players with limited college experience in hopes of unlocking their ceilings, as seen with Griff McGarry and Spencer Howard. However, the current front office, led by Dave Dombrowski, Preston Mattingly, and Brian Barber, has only drafted one college player in the first round in recent years. Given Howard’s struggles with command and McGarry’s inconsistency, the team may hesitate to take a similar risk this time around. Dietz’s lack of a reliable changeup and his injury history further complicate his draft profile, leading to a notable risk of transitioning to a relief role.

While I initially hesitated to focus on pitching in this draft class after the team’s heavy investment in arms last year, back-to-back mock drafts from Baseball America have included Dietz as a potential selection for the Phillies. While his untapped potential is intriguing, the numerous red flags surrounding his profile leave me feeling cautious. If the Phillies decide to draft him, I wouldn’t be upset, but I would certainly feel a sense of underwhelm.
