Texas Rangers Top 38 Prospects

Below is an analysis of the prospects in the farm system of the Texas Rangers. Scouting reports were compiled with information provided by industry sources as well as my own observations. This is the sixth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.
A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.
All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

Other Prospects of Note
Grouped by type and listed in order of preference within each category.
Triple-A Depth
Aaron Zavala, OF
Trevor Hauver, OF
Dane Acker, RHP
Peyton Gray, RHP
Trey Supak, RHP
Zavala and Hauver are corner outfielders without a carrying tool. Strangely, neither Acker’s velo nor his control improved upon a shift to relief. He’s a four-pitch guy who sits 93-95 with good extension. When he keeps his slider down, it’s above-average; when he doesn’t, it’s a line drive. Gray is a 30-year-old journeyman who missed a ton of bats during a monster spring. Hitters struggle with his hopping changeup; he otherwise has 90s-era stuff. I always root for phantom big leaguers to get their Maggi moment, and Supak has the requisite durability, control, and breaking stuff to eat low-leverage innings to earn his.
Reliever Metroplex
Ben Abeldt, LHP
Eric Loomis, RHP
Joey Danielson, RHP
Kolton Curtis, RHP
Brock Porter, RHP
Michael Valverde, RHP
Maicol Reyes, RHP
Adrian Rodriguez, RHP
Janser Lara, RHP
Geury Rodriguez, LHP
Alejandro Chiquillo, RHP
Owen Proksch, LHP
Wily Villar, RHP
Like the Dallas area itself, there’re quite a few people here. Abeldt was Texas’ fifth-rounder last year. The southpaw missed his junior year at TCU recovering from Tommy John surgery. Prior to the injury, he was an excellent reliever with good stuff out of a low slot and deceptive motion. If nothing else, he looks like he’ll be a nightmare for lefties. Loomis is a late-round pick from the 2024 draft. He charged to Double-A in his first pro season and has a couple things that jump off the sheet, including a low release and good whiff rates on his fastball and slider. He’s a stiff mover with below-average control, though. He’s a guy analysts will probably like more than scouts. Danielson touches 98 and flashes an above-average slider. He crushed High-A, but he struggled at Frisco and in the AFL last year, and has the look of a potential up-down arm. Curtis can spin it, and between below-average deception and a low-90s fastball, his best path is probably leaning on the breaking ball in a relief role. While 2023 Porter doesn’t seem like he is coming back, Brock righted the ship somewhat last season after an alarming 2024. He still has the arm strength and stuff to pitch in a big league bullpen.
Even by the standards of “big stuff, no clue where it’s going” that characterize this section, Valverde’s an extreme case in both directions. Last year, Eric wrote that “Valverde’s best sliders are right up there with the best ones you’ve ever seen in your life” and that’s true. He might also never get out of A-ball. Reyes touches 98 and could have two plus pitches at maturity. He’s a 40 athlete, though, and was very scattered after a late-season promotion to the Carolina League last year.
Adrian Rodriguez has two plus pitches and throws 100, but at some point you have to hit the box. Lara was out of affiliated ball for about half a decade before he reappeared with Texas last season. Now 29, he’s got two average pitches and has performed pretty well at Double-A. Geury Rodriguez is a lefty with average arm strength. He can spin it, too. The rub is that he’s not in the zone much and the stroke is pretty long. Chiquillo leans on his above-average slider and has a chance to get to an average fastball in short stints, which makes him a potential middle relief option. Proksch was Texas’ ninth-rounder last year. He’s a lefty with 40 arm strength, but his deceptive delivery resembles Madison Bumgarner’s and he’s got a plus slider. Villar is a 6-foot-4 IFA who signed last year at the age of 26, which is unheard of. He touches 100 and can spin it, though he hasn’t found a good breaking ball yet and can be wild. Regardless, there’s developmental runway left, and it’s a great story even if he never pans out. You’re never too old to follow your dreams.
Carolina Bats
Braylin Morel, OF
Luis Marquez, INF
Maxton Martin, OF
Antonis Macias, 2B
Gleider Figuereo, 3B
Pablo Guerrero, 1B
John Taylor, INF
Rafe Perich, INF
Hector Osorio, OF
Marcos Torres, OF
Morel has thumped on the complexes for a few years, but his measurable power was down in 2025. That’s not ideal for a maxed-out corner outfielder with no approach and shaky pitch recognition skills. Marquez doesn’t have big tools, but he could play forever as a singles hitter with a reliable glove up the middle. A little more speed and/or arm strength would get him to average at short and do wonders for his career. Scouts familiar with the family have noted the uncanny physical and swing resemblances between Maxton and his older brother Mason, a power hitter who topped out in Triple-A due to hit tool issues. Martin the younger also has crude feel to hit and often looks unbalanced against spin. He has a fourth outfielder ceiling. Macias has barrel feel and a good approach, but light tools everywhere else. Figuereo has power but also a lot of miss and chase, and there’s a good chance he’s a first baseman at the end of the day.
The son of Vlad and younger brother of Vlad Jr., Pablo Guerrero is also going to have plus power or better. He has his dad’s approach but not nearly his athleticism nor feel to hit, and he’s raw defensively at first. Taylor was an indy ball signing last year. He’s the least flashy guy in the system, but he’s reliable at short and I think he’s going to play in the big leagues. After seeing Perich go nuts on the backfields one day, he’s always been “Rake” in my internal monologues. He’s a switch-hitter with a viable blend of power and contact from both sides. It hasn’t materialized into production yet, but there are ingredients to stay with. Osorio has hit skill and a mature approach; he’s got a tweener’s blend of speed and power. Torres is still playing center, but he’s in a similar overall bucket with a bit more pop and a lesser approach. I was mildly surprised to see that those two have been asked to repeat Low-A, where they were solid, if not special, last season.
Catchers
Josh Springer, C
Julian Brock, C
Ian Moller, C
Springer has feel to hit and a projectable frame. There are enough question marks — Will the closed stance give him problems covering inner-third velo? Can he get his pop times on the right side of two seconds? — to keep him down here for now, but this was a nice find in the 12th round for Texas. Brock can block and, at least when he’s not trying to launch the ball from his knees, throw. It’s a light bat with a little pop but not much feel to hit. He projects as a team’s third or fourth catcher. Moller is, or at least was, a somewhat famous catching prospect. He’s reached Double-A, but it doesn’t look like he can hit.
Possible Starters
Mason McConnaughey, RHP
Dylan MacLean, LHP
Kamdyn Perry, RHP
McConnaughey has good command and quality secondaries, enough so that he likely would have been an early-round pick in the 2025 draft even with 40 arm strength. He blew out early in the season, though, and fell to Texas in the fourth round. Hopefully he’ll get back on the mound later this season. MacLean signed for more than a million bucks back in 2020. He’s a pitchability lefty with good control but pretty light stuff outside of an above-average curve. Perry was a late-round high school pick in 2023 who held his own at Low-A last year. His low-slot, sinker/slider blend looks spot-starter quality.
Complex Kids
Johander Rubio, RHP
Anthony Astudillo, RHP
Jhon Simon, INF
Saivel Zayas, OF
Oliver Guerrero, OF
Javier Sanchez, C/1B
Marco Argudin, CF
Andry Batista, RF
Rashawn Pinder, OF
Jayln Pinder, INF
Rubio isn’t a big guy, but he touches 96 in his starts and gets nearly 20 inches of vertical break on average. He pairs that with a sweepy breaking ball, sometimes slurvy, sometimes flatter. The IVB and feel to spin jump off the spreadsheet, and Rubio posted good numbers in the DSL. It was his junior year there, though, and his feel for release isn’t great despite an otherwise low-maintenance delivery. He’s a person of interest on the domestic complex this year. Astudillo throws strikes and performed in 2025. It’s 40 stuff and arm strength presently, though, so he’ll need to find more velo, which’ll be a challenge because he’s not all that projectable. Simon produced in the DSL and looks more physical than a lot of his peers, which is not necessarily a good thing. Zayas was one of the younger players in the DSL last year. He has power and speed, so it’s worth keeping tabs on him even though his immature feel to hit keeps him in the slow lane for a while.
Guerrero has a looping, low-ball swing and has the look, if not yet the data or production, of a corner outfield masher. Sanchez was one of the ACL’s youngest players in 2025. He mostly played first base but caught a little bit as well. He makes a lot of contact, and it’s age-appropriate for him to repeat the complex and see if he can hit for more pop in the second go around. Argudin was a 19-year-old Cuban signee last year. He’s a plus runner with good instincts in center, and while his age makes it tough to take his dominant batting line at face value, he has a nice swing and made too much good contact for us to not keep tabs on him. Batista has power projection, and for a guy who’s really raw, he made a viable amount of contact last summer. Older brother Pinder is toolsy and twitchy, and despite limited baseball feel, held his own in the ACL last summer. He’s the kind of athlete teams keep around just to see if something will eventually click. Younger brother Pinder is cut from a similar cloth.
System Overview
Trades have thinned this system considerably. The MacKenzie Gore blockbuster especially, but there are still prospect-eligible players who left Texas in deals that shored up the Rangers’ championship roster in 2023. It’s a tolerable price to pay for all the rectangular fabric dangling off of flagpoles from Arlington to Surprise.
Strong work from the international group has kept this system afloat even with those departures, particularly in the small-dollar demographic. Winston Santos and David Davalillo were Top 100 guys for us this winter, and they cost all of $40,000 combined to sign. On top of that, there are relevant prospects who signed for peanuts running around all over the place. Emiliano Teodo, Leandro Lopez, Wilian Bormie, Jesus Lafalaise: All of them inked deals for $10,000. There’s a similar, if less extreme, dynamic at work domestically, as this list also has plenty of mid-round players projected ahead of more expensive signees from recent drafts.
The big money on the international side has flowed toward intriguing athletes, which the Rangers have long had a knack for finding. The throughline of projectable Latin American signees connects across GMs and scouting directors, and has continued in recent years with guys like Paulino Santana, Yolfran Castillo, and Elian Rosario. Out of this seemingly ideal putty, though, the Rangers haven’t reliably generated impact baseball players. Leody Taveras, Maximo Acosta, Yeison Morrobel, Anthony Gutierrez if things don’t click soon… These are just a few examples of really interesting teenage athletes who didn’t quite figure it out at the plate to the extent that once looked possible. It’s perhaps unfair to apply that lens to guys like Castillo or Santana, but you can understand why there might be some projectability fatigue among Rangers fans.
I have one other Eeyore-ish observation. If I had to pref out all the 40+ and higher types I’ve written about this cycle, I think a lot of the names on the list above would settle toward the bottom of their respective tiers. The 50-FV players did on our Top 100 list, and three of the 40+ guys are very volatile and years away from contributing. They belong where they’re ranked, but this is perhaps a system more vulnerable to rolling snake eyes a bunch than you’d think just looking at the list.
To conclude more optimistically, the strength of the system is its upper-level pitching, which is ideal for a franchise on the back nine of its competitive window. Texas is well stocked in upper-level starters who can eat innings this summer, and there are several relievers who are either ready to go now or who could be pushed into big league roles with just a bit more seasoning. And, as always, there is no shortage of lower-level athletes who can be tossed into a deal to help at the deadline if the Rangers stay competitive.

Years ago fangraphs writer(s) did research to approximate the value of each player based on pitcher/position player and fv rank. Using this system is all the farm systems so far graded since 2025 season ended. To see each players value based on fv and position/hitter you can see here. https://www.fangraphs.com/prospects/farm-system-rankings
While I like many of these position players, I like Devin Fitz-Gerald more (yes, including Walcott) and think he will be “the one that got away” from that trade.
Gore has been incredible, of course, so it’s all good. But I really like Fitz-Gerald’s game and think he’ll be a top 30-50 prospect in baseball this time a year from now.
Gore is incredible every March-June. It’s what he does after that is where the struggles have been
Has Justin Foscue graduated out of Prospect Status, or was his MLB stint so horrible that he has fallen out of the bottom?
He graduated on active roster days.
His page doesn’t list him as a graduate
I understand why Yolfran Castillo is a 50 with those grades, but that max exit velocity is not showing up at all right now in game power. His isolated power last year was under .100 and it’s not like he ran a high batting average either.
If everything is there mechanically then I think there must be large disconnect between his pitch recognition and the mechanical tools. I would guess he has no real idea of what to swing at because he is patient (about 45% swing rate), low swinging strike rate (about 8%) and high called strike rate (about 19%). This would be consistent with decent max EVs and his complete lack of game power.
But Brendan gives him a 60 on pitch selection, which seems like an awfully aggressive prediction. He has got a very long way to go.
Now there is some precedent for a guy with this combination being a competent major league hitter. Josh Smith’s swing rate, contact rate, swinging strike, and called strike are all very similar to what Castillo is doing now. The difference is that Smith sometimes hits homers, which would theoretically be solved by Brendan’s assertion that the game power is coming.
That means in theory this can work. I am just also worried about all of the other guys in A-ball who we don’t remember with that same combination.
I’m with you on this. It can be difficult to differentiate between a hitter who is patiently looking for a specific pitch to drive and one who is passive, but it’s a vital distinction to make because the former is strength while the latter is a big problem. I can’t remember too many prospects who became successful major leaguers with that kind of passivity.
Yes–I always wonder about these guys who are supposedly superior athletes who just don’t perform. It only makes sense if he has some serious flaw to fix in order to be a 50. This is not a case of him just learning to do the same things better as he goes up the ladder.
There is a path for this. If he’s an average shortstop defensively and he makes huge strides forward in his swing decisions / plate recognition he could regularly put up seasons like Kyle Farmer or Jose Iglesias in 2021, and they had wRC+’s at about 90.
That’s a 50.
BUT
He has a long way to go before he projects to hit like that. I know that minor league wRC+ and surface stats lines aren’t immediately interpretable without context but he hit one homer over 378 PAs last year and only posted a .315 OBP. With an 80 wRC+ he’s a low end utility guy.
There is a lot of risk in this farm, even the older starters like Davalillo ( is the FB good enough?) and Santos (injury?) have big questions.
I like Walcott and those top 3 pitchers a lot despite the huge risk on all of them, and after those four and Jose Corniell I am just unimpressed. I don’t think there is anyone in this group who I am higher on than Brendan is and a few where I have more concerns (Castillo, Kling, Church). It actually looks a lot like the A’s system that way.
Props to whomever wrote the title.
D’oh.
I’ll just reiterate what I said in the Top 100 piece about the joy of seeing Caden Scarborough in person without knowing anything about him. It’s the coolest feeling to attend a random minor league game and be instantly convinced that one of the players will reach the major leagues. He was the most interesting pitcher that I saw in person last season.
I did that in DC, I saw Bobby Bonilla playing in A ball and was overwhelmed. A great experience.
I saw Ben Davis in A Ball. I have absolutely no scouting expertise. He looked different than the rest.
It has been two or three years now since I have been able to get to a minor league game—I think I got spoiled living within a 3 hour drive of a half dozen minor league stadiums, now I live in a place where I think there is only one? And it’s at the edge of that range.
But the last time I went I saw Ronny Mauricio before he got called up and everything about him looked so athletic. I could understand why the scouts went crazy about him.
Saw Ezequiel Tovar play against AA Richmond a few years ago and you could just tell he was a future big leaguer. Was like 2-3 years before he got his big contract.
I mean, you could arguably extend the international side prospect fatigue back to Mazara, Guzman, Alfaro, even Profar.
Is 50 years the cutoff for giving a development leash? Because we’re quickly approaching that for Pudge and Juan Gonzalez.
I think the most frustrating part about the Rangers prospect-dom in last 10 years, is we just don’t have much success with drafting and developing above average big leaguers.
Success stories:
Langford – 2023 1st round, 4th overall. probably the best player we have drafted in past 10 years and he fell into our lap. already 7+ WAR, and you can still nitpick on his defense and swing decisions. great player, but he was pretty much already developed.
Carter – 2020 2nd rounder. probably the best success story the Rangers can take credit for. no one really knew about him and he shot through minors, contributed to an amazing 2023 and World Series. Fought injuries past 2 years and looks fantastic to start this year, hope he keeps it up.
TBD:
Leiter – 2021 1st round, 2nd overall. he has been so up and down developmentally. I love the strides he’s made recently but with the upside they painted on him, and with his stuff, you’d hope he would have turned into a legit 2-3, heck even a 1. i’d love for that to happen but who knows.
Rocker – 2022 1st round, 3rd overall. injuries have killed his career, but i’m hoping there’s a chance he hangs around to become a serviceable big league starter. don’t think the Rangers are too blame why he hasn’t lived up to the hype, but certainly part of the picture.
Jung- 2019 1st round, 8th overall. great in 2023, awful or hurt every other year. his swing decisions are erratic, i’ve started to lose patience on him. Hope he turns it around, but its been a down arrow every year.
Misses:
Cole Ragans – 2016 1st round, 30th overall. pretty crazy we had him 9 years, we ship him off for Aroldis Chapman (thank you for the WS), but then he immediately turns into a top of line rotation starter after leaving us. Just another indication our development is lacking somewhere.
Cole Winn – 2018 1st round, 15th overall. great he is finally contributing to the big league in a successful RP role, but they thought he would be much better with the draft capital.
Other first rounders without writeups:
Jake Skole (?), Kevin Matthews (?), Lewis Brinson, Chi Chi Gonzalez, Luis Ortiz (?), Dillon Tate (ugh), Bubba Thompson, Justin Foscue, Malcolm Moore, and Gavin Fein.
i hope Carter, Langford keep it up, and Leiter and Rocker continue to improve, and Jung turns it around. But just not a lot of homegrown talent where you expect it to be IMO. I don’t know how Kip Fagg has kept his job for so many years.
It’s been a bit longer than 10 years, really. A complete list of all players to debut for the Rangers since 2010 and amass 10 career WAR for them:
That’s the entire list (unless you want to count Yu Darvish, but he certainly didn’t need any development on the Rangers’ part), and Perez didn’t get there in his initial team control years, only getting over 10 after he left and then came back. I guess Adolis Garcia also went over 10 WAR for the Rangers and only briefly played for the Cardinals before that, but he also never played a game in Texas’s minor league system.
There’s a few on the current team who might get over that hump. Langford almost certainly will, but like you said he was already basically fully developed- any team that had the pick there could have gotten this out of him.
Yeah hard not to keep going back. There are some random wins here and there, but the guys you expected to be awesome just didn’t pan out. Profar wasn’t successful until far later and wasn’t as good as he was supposed to be. Same with Mazara. I could go on.
Profar also only got really good when he juiced the last couple of years, before that he alternated years where he was good but not great with years where he was replacement level or worse.
Putting 50 grades on 23-24 yo who haven’t debuted/shown anything in ML yet is farfetched…historically guys this age who are still MiL’s do not end up being “avg” ML starters
