Arizona Diamondbacks Probably Skip Pitching in 2024 Draft

College Pitchers Are Thin This Season

Jackson Flora from UC Santa Barbara and Cameron Flukey from Coastal Carolina are the only college arms that currently crack the top‑15 prospect lists. Both are viewed as mid‑rotation starters at best, which limits their immediate impact. The rest of the draft class lacks the depth that teams usually expect from the college level. For Arizona’s front office, this means there aren’t enough promising arms to justify a early‑round pick dedicated solely to pitching.

Arizona’s Development Challenge

The Diamondbacks have a reputation for a poor pitching pipeline, and the organization’s recent results reflect that reality. While there are signs of gradual improvement, the system still trails many of its competitors. This weakness makes the decision to invest a high draft pick on a pitcher even riskier. Consequently, Mike Hazen’s staff is under pressure to avoid over‑committing capital to a position that historically yields uncertain returns.

High‑School Southpaws Offer upside

This year’s prep left‑handers are the most notable bright spot in the draft. Gio Rojas, Jared Grindlinger, Brody Bumila and Logan Schmidt are all listed among the top‑30 prospects. If all four are selected in the first round, it would match the 2000 draft’s record for left‑handed prep picks. However, prep arms are notoriously unpredictable; only a handful of them ever reach the majors, and the odds of success are low across the board. For Arizona, it remains an open question whether the organization will gamble on a group of untested arms.

Historical Success Rates for First‑Round Pitchers

From 2017 through the COVID‑affected 2020 draft, 65 first‑round pitchers were taken. Just six of those arms have amassed 10.0 bWAR or more, led by Drew Rasmussen’s 13.8 bWAR. Hunter Greene is closing quickly on Rasmussen’s total, while twelve selections have posted negative value. Thirteen never made it to the majors, and another twenty‑plus have struggled to establish themselves as reliable starters. These numbers illustrate why many teams treat early‑round pitching picks as a high‑risk proposition.

Brody Bumila: The Standout Prep Left‑Hander

Bumila towers at 6‑9 and fires a 96‑98 mph fastball that has topped out at 101 mph when he pushes it. His low release point adds perceived velocity, and his changeup features solid fade and good velocity separation. A developing slider shows promise as a potential plus pitch with further refinement. Scouts see him as a top‑10 to top‑15 talent, though most projections keep him in the late first round or early second round. His age—still 18—means he will need a patient development program to refine his secondary stuff while he continues to throw elite heat.

Why Arizona Likely Stays the Course

Despite speculation, Hazen’s typical drafting philosophy emphasizes proven talent over risky strikeouts. The current pool offers few standout college arms, and the prep left‑handers, while exciting, carry a history of low conversion rates. Arizona’s limited success in developing pitching also discourages a big investment at #15 or #31. As a result, the Diamondbacks are expected to reserve those picks for position players or more reliable prospects.

The 2024 draft portrait for Arizona is clear: a dearth of quality college arms, a handful of intriguing prep left‑handers, and a front office wary of repeating past mistakes. Unless the organization decides to overhaul its development approach, the prevailing outlook is that the D‑Backs will stick to their traditional strategy and pass on a pitching pick at the top of the draft.
