This is the second year we’ve done this, looking at names in the Diamondbacks system who might be able to help the team this season. 2025’s selection was a bit of a mixed bag, shall we say. We were one of the earlier passengers on the Tim Tawa bandwagon, and he ended up playing 74 games for the D-backs. At the other end, Seth Martinez found himself designated for assignment about three weeks after our article. So it’s safe to call my track record “mixed” in this area, and that’s perhaps being kind. But, never one to be daunted by being incorrect, I figured I’d try again this winter.
However, I will expand slightly outside the 40-man roster, because there are certainly some intriguing possible candidates who haven’t yet been added to it. There should certainly be plenty of space to do so, because the D-backs will have at least four players (Corbin Burnes, Justin Martinez, A.J. Puk and Blake Walston) going on the 60-day injured list as soon as it becomes available – theoretically the start of spring training, but effectively Opening Day. I would have Lourdes Gurriel Jr. on there too, but based on recent reports of his progress, he might be looking to come back sooner than early June. If so, then the team might be fine with using the shorter IL for him.
Therefore, for inclusion I’m just going to say that the player in question can’t have appeared for the D-backs previously. This rules out somewhat known names like Cristian Mena and Yilber Diaz. But also less familiar ones like Philip Abner, although you may have blinked and missed his 3.2 innings for the team last year. We begin, instead, with a choice which hardly counts as pushing out the boat. For Kohl Drake is currently the consensus top pitcher in the Diamondbacks farm system. Admittedly, not long ago, “having a pulse” would be a credible main criteria there. But largely courtesy of Merrill Kelly, things are looking better there than they were.
That “pulse” statement is little if any exaggeration. Of all the pitchers in MLB Pipeline’s current top 15 Arizona prospects, half of them came from Texas in the deadline trade for Kelly last July. In addition to Drake, Mitch Bratt and David Hagaman also arrived in the D-backs’ system. But Drake is the highest ranked (#6) and, at the age of 25, is also the closest to the major leagues. Right now, it would appear the left-hander will need help – most likely a health issue affecting more than one expected starter – to crack the Opening Day rotation. But he’s going to be near the top of the list for a call-up when necessary, and from previous history, that will not be long into the season.
Drake was originally an 11th round pick by Texas in the 2022 draft, so has already over-performed. He comes out of Walters State Community College in Morristown, TN, and he has a real shot at becoming their best-known player. So far, that is probably another Ranger, Brett Martin, and you’d be forgiven for going “Who?” Though around SnakePit Towers, it would be reliever Chad Bell, because Mrs. SnakePit rented a house to him one spring training. You’d be forgiven for going “Who?” there as well, but we were excited to see him in action when we visited Seattle in 2017.
After a rough start to his pro career in 2023, posting a 6.36 ERA across 46.2 inning, Drake had a much better 2024. He roared through three levels of the Texas system, starting in A-ball and finishing in Double-A. He dominated the lowest tier, posting a K:BB of 71:9 across just 43 innings, though was relatively old for that level. The ratio did decline at the higher levels, but Kohl was still striking out a batter per inning in Double-A, with a 3.10 ERA across five starts. He returned there to start 2025, and was better still: 12 starts, a 2.44 ERA and an impressive 70 strikeouts across 55.1 innings. Kohl was named Pitcher of the Month in the Texas system for June.
That got him a promotion to Triple-A at the beginning of July, and he spent the rest of the season there, both before and after the trade which brought him into the Arizona system. There’s no denying, Drake struggled in the unforgiving environment of the PCL, allowing 24 hits over 16.2 innings, leading to a 9.18 ERA. He may have been hurt, as his season ended after a decent outing (4 IP, one unearned run) on August 20th. He was placed on the IL with a shoulder sprain the following week, though is expected to be fully recovered when pitchers and catchers report to Salt River Fields next month.
He was added to the 40-man roster earlier this off-season, a no-brainer decision to protect Drake from otherwise being available in the Rule 5 draft. That gives him another benefit over some alternatives, in that there’s no need to make room for him on the larger roster. His velo has increased by 3-4 mph since he pitched in college, now sitting around 93-94 mph. MLB Pipeline says, “His combination of size and a short arm action provides some deception, as does his flat approach angle. If he can continue to get more advanced hitters to chase his curveball and changeup, he could make it as a No. 4 starter.”
It’s interesting to think how the rotation will shape up for the D-backs in the coming seasons. We have Corbin Burnes and Brandon Pfaadt under contract through 2030 (plus two team option years in the latter’s case); if Merrill Kelly’s vesting option kicks in, he and Ryne Nelson are controlled until the end of 2028. And Eduardo Rodriguez is signed through 2027 (plus a rarely-exercised mutual option). Soroka is clearly intended as a stop-gap until Burnes returns. Though health is always a potential factor, it appears that Mena, Drake or any other candidate will need to prove themselves capable of a rotation spot for the next couple of years.
