Organization Prospect Rankings

• 
  Ranked Texas Rangers #8 prospect in 2026
  BA Grade/Risk: 50/High
  
  Adjusted Grade: 35
  
  Track Record: Castillo signed with Texas in 2024 out of Venezuela and quickly showed exemplary bat-to-ball skills. He lasted just 20 games in the Dominican Summer League—where he hit .414/.552/.471—before the Rangers bumped him to the Arizona Complex League. Although the venue changed, Castillo continued producing at a stellar level. He split his 2025 season between the ACL and Low-A Hickory, where he continued to make plenty of contact but little impact.
  
  Scouting Report: In 2024, Castillo’s body was long and lanky with plenty of room for more strength. Scouts who saw him a year later said he had made some progress in that area, but a large chunk of his future depends on whether he can get even stronger and turn more of his singles into extra-base hits. Castillo’s swing is a bit choppy, and he tends to make his contact deeper in the strike zone. Those traits, plus below-average exit velocities, have led to limited offensive success outside of contact abilities. He has just 21 extra-base hits—and only one home run—in 421 career plate appearances. That likely limits his upside to a bottom-of-the-order hitter. Scouts are sold on Castillo sticking at shortstop, and he ranks as the best defensive infielder in the system. He’s a smooth fielder with strong instincts, soft hands, plus range and an excellent internal clock. His arm strength is plus, too, and he got 10 games of experience at third base as well. Castillo is an average runner who has stolen 28 bases in 34 career attempts.
  
  The Future: The next few years will be telling for Castillo. If he can revamp his bat path and add strength, he might be able to hack it as a shortstop who hits toward the bottom of the order. If not, it will be tough to find a path to the big leagues.

  Ranked Texas Rangers #7 prospect in 2025
  BA Grade/Risk: 55/Extreme.
  
  Track Record: The Rangers have never been shy about promoting their best prospects, and Castillo earned that honor in 2024. He signed out of Venezuela in January 2024 then showed sublime bat-to-ball skills in the Dominican Summer League. He struck out just eight times in 97 plate appearances before earning a bump to the Arizona Complex League. He continued to put lumber on leather in Arizona and finished his season with just 15 strikeouts in 163 plate appearances. Castillo’s 35th and final game was the only one during which he failed to reach base.
  
  Scouting Report: Castillo’s signature skill is his ability to swing without missing. His miss rate overall was just 11.6%, and he whiffed just 5.4% on pitches in the zone. The contact came with moderate impact, including a max exit velocity of 102.6 mph despite just five extra-base hits and zero home runs. Scouts who saw Castillo over the course of the season were impressed by his defensive chops, including range, athleticism, a sound internal clock and plus arm strength. His soft hands and sound footwork also lend credence to his ability to stick at shortstop. He’s not a burner but could settle in as an average runner who makes up for a lack of speed with the type of first-step quickness which should serve him well at shortstop. All of his tools should play up as he adds strength to his lanky, 6-foot-3, 165-pound frame. If he’s able to stack muscle on top of his athleticism, power could become a bigger part of his game. Scouts also noted an uncommon level of maturity for a player of his age and experience.
  
  The Future: Castillo mastered the complex levels. Now, he’ll head to Low-A Down East with eyes on doing the same in full-season ball. He’s the second-best shortstop prospect in the organization and has the skills to be one of the system’s breakout stars in 2025.
