As a high school standout at Gulliver Prep, Del Castillo was a bat-first catching prospect who was ranked No. 194 on our Draft Top 200 list in 2018. The White Sox took a flier on him in the 36th round that year, knowing he was certain to honor his strong commitment to the University of Miami. He quickly showed his bat would play when he posted a .995 OPS as a freshman. He upped that to 1.025 over his first 16 games in 2020 and while his offensive production was inconsistent this spring, he was still thought of as one of the top position players in the 2021 Draft class.
There is a lot to like about Del Castillo’s offensive profile, starting with his outstanding left-handed swing. He has a strong tendency to barrel up the baseball with an advanced approach, leading to more walks than strikeouts over his first two years with the Hurricanes. He hit 14 homers in just under 350 plate appearances at Miami. While Del Castillo didn’t open 2021 with a ton of pop and he didn’t dominate as much with wood during his time in the Cape Cod League in 2019, he did hit five balls over the fence in 37 games that summer.
Just like when he was in high school, there are still some reservations about whether he can stick behind the plate long-term. His arm strength has improved and he tends to be accurate, but he’s not quiet enough with his receiving, showing a tendency to snap at balls too frequently. A team that feels he can improve and stick at the premium position will consider him in the top third of the first round, but his offensive profile alone will make him a first-rounder regardless of his defensive home.
Del Castillo was a strong performer in his first two years at Miami but saw his slash line drop to .275/.380/.395 over 54 games as a junior in 2021, hurting his Draft stock. The D-backs selected him 67th overall that summer and signed him for $1 million. It’s been a bumpy process, but Del Castillo started to show promising results in hitter-friendly Double-A Amarillo (.273/.386/.505, 12 homers in 63 games) last year before joining Triple-A Reno for 37 contests. Back with the Aces to begin 2024, the former Hurricane was one of the Pacific Coast League’s consistent standouts throughout the summer and earned his first Major League callup in August.
Once considered a hit-over-power prospect, the 5-foot-11 left-handed slugger has taken off with his best pop in pro ball in ’24. Entering late April, his hard-hit rate, barrel rate, 90th-percentile exit velocity and expected slugging percentage were all near the top of Triple-A leaderboards -- a sign that his power would play anywhere beyond the launching pads of the PCL. He’s become more aggressive in pursuit of that power, at times chasing more than he should, but the approach has also helped him cut down on strikeouts with good contact rates in zone.
A near bottom-of-the-scale runner, Del Castillo needs his bat to play up because he’s long faced defensive questions, particularly with his footwork. D-backs officials have expressed enthusiasm about his gains behind the dish in 2024, and Del Castillo has most noticeably adopted the one-knee-down stance that helps improve framing. He’s shown pop times as low as 1.90 with Reno -- just below MLB average of 2.0 -- but he hasn't caught many runners stealing bases. Still, Del Castillo’s offensive steps forward have him close to being a Major League backup catcher who can provide some lefty thump off the bench.
As a Florida high-school standout, Del Castillo was a bat-first catching prospect ranked No. 194 on our 2018 Draft Top 200 list. The White Sox took a flier on him in the 36th round that year, knowing he was certain to honor his strong commitment to the University of Miami. He quickly showed his bat would play by posting a .995 OPS as a freshman. He upped that to 1.025 over his first 16 games in 2020, and while his offensive production was inconsistent in 2021, he was still thought of as one of the top position players in the 2021 Draft class. The D-backs selected him 67th overall and signed him to a slightly above-slot $1 million bonus.
There’s plenty to like about Del Castillo’s offensive profile, starting with his outstanding left-handed swing. He has a strong tendency to barrel up the baseball and shows an advanced approach, which led to more walks than strikeouts over his first two years with the Hurricanes. He also belted 14 homers in just under 350 plate appearances at Miami, though he didn’t hit for much power in 2021.
There are some reservations about whether he can stick behind the plate long-term, though he received better than expected in his pro debut, and his leadership skills, as well as the fact that he’s bilingual, are also beneficial. His arm strength has improved and he tends to be accurate. Castillo needs to work on his footwork, but the improvements he’s made in other areas bode well for his ability to get better in all facets of the game. While the D-backs hope Castillo is able to stick behind the plate, his bat is his carrying tool. If he has to change positions, his offensive skill set is still likely to find a way to get him in the lineup.

Gulliver Prep in the Miami area has had five players taken in the top five rounds, the most recent being infielder Adrian Marin, a third-rounder in 2012 currently in the Orioles organization. Del Castillo might be next on that list, though his bat-over-glove profile may keep him from reaching Marin's spot.
Scouts universally like Del Castillo's swing from the left side of the plate. He recognizes pitches well, with a solid game plan, and should be able to hit for average. Because he doesn't expand the zone, he drives good hitters' pitches and has plenty of raw power to tap into. His work behind the plate remains behind what he can do in the batter's box. His arm is fringy, though it tends to be accurate, and his receiving skills will need continued refinement at the next level. If there was a need to move him out behind the plate, some feel left field would be the most suitable position for him.
Del Castillo has a strong commitment to the University of Miami, so it might be tough to sign him beyond a certain round or bonus figure. Any team that makes a run at him will be buying the bat along with the hope that his defensive work improves so he can stay behind the plate, maximizing his value.
