Because the prospect times focus on the Texas Rangers Farm system, we start with Jose Corniell, the prospect of the Rangers.
Jose Corniell was originally signed by the Mariners in 2019 for $ 630k before he was traded to the Rangers in 2020 for Rafael Montero.
He has shown a significant improvement every season, culminating in a large outbreak in 2023 when he placed a 2.92 ERA in 101.2 threw innings, with most of his starts in High-A. During those innings he had a total of 119 strikeouts against only 31 walks and he maintained a strike rate north of 67 percent.
Unfortunately, he missed the entire season of 2024 after an operation by Tommy John.
Corniell returned in 2025 and threw only 38 innings, but was very effective and placed an ERA of 1.89 while he had beaten 28 percent of the batters between Double-A and Triple-A. His Fastball is a strong pitch that is 95-96 km / h with Carry and Arm-Side Run and plays particularly well at the top of the Slagzone.
His sweeping machine is a plus title, sitting in the Lage 80s and regularly shows more than ten centimeters of radical action. It is comfortable to throw this pitch to both left and judges. The High-Spinning Curveball, sitting around 80 mph, is an important odor generator, which shows an impressive break with two areas. In 2023, Corniell added a semi-sentner in 2023 (to work in the zone and induce ground balls) and a cutter (a pitch that was an important part of his breakout from 2023), and he also combines a change against left, with a late break.
Given his strong command and the progress he has shown after Tommy John, the stuff is certain. Since he is even further away, Corniell should be the best arm on this talented surprise team in the Afl.
Kolton Curtis is another Rangers -forecast that I will keep an eye on. He threw 66.0 innings exclusively with the High-a Hub City Spartanburgers. He ran 44 batters only a battle 75.
Winston Santos showed flashes of his high-end strikeout power in his short 17.1 innings on the upper levels (Double-A Frisco and Triple-A Round Rock). Despite his 6.75 ERA, he hit 26 batters against just 7 walks, which demonstrated his quality things. He had been the sidelines for most of the season with a stress reaction in his back.
Daniel Espino Is another exciting arm, a whose return to the hill was uncertain. Before a Triple-A appearance in September 2025, Espino’s last in-game Pitch was in April 2022. His 2022 season ended after only 18 innings due to a knee injury. He then missed a whole 2023 because of a shoulder stem that led to a scary front capsule repair surgery. He needed a second shoulder operation in the spring training 2024, this time with both his capsule and rotatorm surchet.
When he is healthy, Espinos High-End Fastball is one of the best in the minors. It is regularly north of 97 MPH and can touch 100 mph, with high IVB numbers. This pitch combines well with a slider that is approximately 87-88 MPH with a nice depth and shorter horizontal movement, which generates many whiffs. To change eye levels, it quickly mixes in a 12-6 curveball in the mid-70s.
His switch, which is at 89-90 km / h, almost works like a double seas with a high carrying case and 14 centimeters arm-side movement. Seeing Espino -Pitch in Arizona will be crucial, and if he returns with his electrical things, his prospect stock will probably rise considerably.
Logan MartinA 12th rounder in 2023 is a pitcher who has posted two consecutive strong seasons. In 2024 he placed a 3.62 ERA over 102 innings with a strikeout-minus-Walk percentage of 15.3 percent. This season in High-A, Martin threw 91.1 innings with a 3.45 ERA.
While his strikeout percentage fell to 20.6 percent, he remained effective.
Martin has repeatable mechanics and shows low efforts, even when he touches 96 mph.
With the bats – we emphasize Sebastian WalcottThe prospect of rangers and prospect no. 4 in general. Yes – we may just be a little partly.
Some can consider the 2025 season of Walcott as a bit disappointing, while he .255/.355/.386 diagnosed with only 13 home runs and 32 stolen base over 552 plate performances while he spent the entire year in Double-A and was 19 just before the season started.
However, there are some positive points. The most important problem for Walcott was a lack of attic, which resulted in a 46 percent ground ball percentage. But when he gets the ball in the air, he often attracts him – a habit that comes well on unlocking his potential power.
Walcott also ended the year with a strikeout rate below 20 percent, and from August that number fell to 15 percent while his running speed rose to 14.5 percent. Walcott .281 with an OBP just below .400 over his last 159 plate performances.
His total contact percentage saw a huge leap and ended the year at 74 percent, with a contact number in the zone north of 80 percent.
Luke Adams Is another interesting prospect with an unconventional swing that is considerably weakened. The results cannot be denied: Adams has booked large swing forecast and performed well for two consecutive years.
He only gathered 315 record performances this season due to an injury, but still shot 11 home runs and stable ten bases, ending with a .231/.417/.436 slash. Despite consistently low batting averages, he hits the ball hard against respectable corners.
He has one of the lowest swing and chase speeds in the minors, who generally winds 33 percent of the fields and less than 20 percent of the fields from the zone. He in turn contacted 79 percent of the fields in general and almost 85 percent in the zone. Adams hit the ball hard, with a 90th percentile exit speed north of 106 MPH, and has hit several balls north of 110 mph.
Carson Roccaforte Stilling a strong season quietly and the year is particularly well finished in Double-A. Between the two levels, Roccaforte struck 18 home runs and stable 43 bases, with a .258/.373/.470 sloping line. His songs improved in Double-A, where he showed better launch corners and hit less often. Although his exit speeds are only respectable, he showed a talent for hitting Pull-Side Home Runs, which resulted in a career-high grade after only ten last season. While the flight speed fell slightly in Double-A, Roccaforte’s launch corners became more consistent and his stroke average on balls in the game (Babip) increased considerably.
Roccaforte finished the year on a high note: over his last 162 plate performances he cut .296/.383/.493 with five home runs, 17 extra basehits and seven stolen base. Expect a solid performance from Roccaforte in the Afl.
