What with the mess in Texas? If you’ve read the first two installments in this series, you’ll know the Rangers are the culprits of their own success in some ways that escape traditional prospect rankings. Baseball Prospectus has SS/2B Kevin McGonigle of the Tigers at No. 2, OF Max Clark also of Detroit at No. 6, SS Aidan Miller of the Phillies at No. 13, and Seattle’s own SS Colt Emerson at No. 15. What do they all have in common? They’re 2023 draftees, who’d be joined or surpassed by OF Wyatt Langford in all likelihood if the 23 year old hadn’t rocketed to the bigs and spent his healthy time in Arlington for the past three years.
Not everything can be accredited to the promotions of players like Langford, OF Evan Carter, INF Ezequiel Duran, RHPs Kumar Rocker and Jack Leiter, and OF Alejandro Osuna, though. Texas dealt away their 2025 first round pick, INF Gavin Fein, and others to bring in LHP MacKenzie Gore and shore up the big league club. Their 2024 selection, last in the round following their World Series championship in 2023, was C Malcolm Moore, has yet to hit in pro ball after a strong Pac-12 career. Rocker and Leiter were the club’s top picks in ‘22 and ‘21, and while both are early enough into their big league tenure to imagine breakouts, they’ve underachieved the 3rd and 2nd pick billing they received respectively. Rounding out the 2020s, data darling 2B Justin Foscue rocketed up draft boards late in the increasingly infamous 2020 draft, but is on the fringes of Texas’ 26-man and now 27 years old with a lost 2025 that’s still looming, with a hamstring strain likely to delay the start of his season. SS Yolfran Castillo is the latest in a series of high-upside, tools first, everything else later prospects in the Rangers’ system and it’s fair to be skeptical of that developmental group, given the hiccups seen with Carter, Josh Jung, and Leody Taveras who’ve flashed promise more than sustained it.
In their system now are a wave of pitchers with promise and an absolute smorgasbord of injury/durability issues and question marks. But the most promising – and frightening from a Mariners perspective – prospect suffered an injury this offseason that will at least delay, if not fully waylay, his 2026.

The Wall Got Caught
Like the Athletics a week ago, the system’s heft rests heavily on one elite middle infield prospect. SS Sebastian Walcott, who will turn 20 this March, is a Bahamian wunderkind whose potential has surpassed his countryman Jazz Chisholm Jr. to be the most hyped player in the history of the Commonwealth. His torn UCL this winter required surgery for an internal brace, which he’s already undergone, and the club suggested it’s possible Walcott returns to play in August or September of this year.
The expectations are understandable – Walcott is a big young man with titanic raw power and arm strength, along with the ample athleticism needed to cover the left side of the infield and maturity to be challenged with a Double-A Frisco assignment at just age 19. While Walcott didn’t star there, he hit competitively, and looked more than adroit in every area of his game.
As with Leo De Vries in Sacramento, there’s a year or two until Walcott is likely to impact Seattle most prominently. But Walcott should see his debut come as Corey Seager makes a more pronounced shift off shortstop, allowing the slugging lefty to focus on his offense. Walcott’s not a lock for short, but his arm is strong enough to be a standout third baseman as well. Walcott’s length and fluidity is impressive, but he does look at times more like Oneil Cruz than Elly De La Cruz at short. Still, combine a left side infielder with 30-30 potential at the dish and that’s as good as anyone in baseball. The Rangers of 2027 and beyond are likely to go as this young man does.
The Heat
Depending on your trusted prognosticators, there may be no other Rangers prospects in the Top-100, or a handful of arms. Much of that stems from your relative taste for some edge-case arms. Scarborough looks the part in many ways that Ryan Sloan does, with a huge frame and deceptive delivery that augments multiple impressive secondaries. The 6’5 righty was a prep signee in the sixth round of the 2023 draft who utterly dominated both Single-A levels. The Sloan mention is physical in part, but ties mostly into the question mark for a 21 year old hurler who completed six innings just once in 2025 and made it through five only four times. While his velocity sits more 93-96, he’s the arm to watch as an ascendant possible top-tier arm for Texas.
Beyond him are a bevy of hurlers with promise and injury troubles. RHP Emiliano Teodo missed much of the 2025 season with injury, but has electric stuff that could charge up a big league bullpen late in 2026 or early in 2027. Also in the mix are RHPs David Davalillo and Winston Santos, both of whom were mere five-figure signing bonus players who’ve crept up the system through diligent improvement. Santos hits upper-90s heat but hasn’t quite figured out a great pairing, making his strikeout numbers in the minors slightly suspect, and dealt with back and hand injuries in 2025 and this spring, respectively.
Davalillo, by contrast, may be convenient for those of you used to watching a Texas pitcher with alliterative Ds for his name play a swingman or back-of-rotation role with plus command and a kitchen sink approach. Dane Dunning, we’ll never forget you, especially if you’re in Tacoma this year. The electrick Izack Tiger is yet another RHP with high-level stuff who is still experiencing delays from his UCL tear, likely to pitch at 25 this year but without innings above High-A. There are a handful more players of this sort in the Texas system than Seattle’s, big stuff, big tools, but track record paucity. It is high-variance, but currently at its low ebb.
Ignorant of Ignorance
The issue with this system is a dearth of depth. The big league roster, were Rocker and Leiter to both deliver on their promise and all else stay equal, would be potent. But a bevy of moderate disappointments once folks have entered this system has left the club shallow, from OF Aaron Zavala (38th pick in 2021) still yet to debut and lacking much sheen, with little in the outfield behind him, while his draftmate UTIL Cameron Cauley (73rd in 2021) swings and misses a lot for someone with his skillset, capping the potential of his blazing speed.
But where this issue shows up most potently is behind the plate.
I mentioned Moore in the introduction, and it bears repeating: the Rangers’ 2024 first round pick is not considered a top-10 prospect in the system, and the system is not well regarded. BP has Moore 15th, BA 13th, and MLBP 18th. When FanGraphs publishes their updated rankings, it’s likely Moore falls similarly, and it is not clear another big league catcher exists in this system even with a heavy squint. Athletic backstop Ian Moller was a fourth rounder in 2021, but has not been able to match the Harry Ford sweet spot in the slightest as a pro. A few rounds later, Texas took C Liam Hicks as well, who’d have helped arrest the cliff dive Jonah Heim took the past two years before departing in free agency, had he not been dealt to Detroit for Carson Kelly. Now in Miami’s backstop rotation, Hicks is one of just four backstops drafted in the 21st century by Texas to both make the big leagues and accrue positive WAR (1.3, second only to Jose Trevino, who also accrued it playing somewhere other than Texas).
That’s all fine if you’re identifying solid contributors like Heim, Robinson Chirinos, or Mike Napoli in trades and on waivers, or going for high-outcome free agents like Danny Jansen or AJ Pierzynski. But the Rangers are not seeming to find their next Pudge Rodríguez, through the draft as the Hall of Fame Puerto Rican would’ve been found if he’d come up a few years later, or elsewhere. That’s the biggest hole in a Texas system that often is so focused on upside, it’s missing anyone who could take a squat. -JT
