Hi, what are you looking for?

Top Prospects No. 21-30

21. Albert Fermin, SS

Level: Rookie DOB: 02/09/09

Fermin was the Astros top international signing in January of this year, signing for $2.3 million. Fermin already produces consistent hard contact, and with his physical upside, there’s reason to believe he could grow into considerable in-game power as he matures. Defensively, Fermin is athletic enough to begin his professional career at shortstop, but evaluators believe his long-term home may ultimately be at third base. With his strong arm and solid instincts, he projects well at either position on the left side of the infield, giving the Astros a versatile and high-upside addition to their international class.

22. Trey Dombroski, LHP

Level: Double-A DOB: 03/13/01

Dombroski was drafted by the Astros in the 4th round of the 2022 draft after a standout career at Monmouth University, including 14 BB/130 K in 95 innings as a junior. The lefty stands at 6’5″ and 235 lbs. While he doesn’t blow you away with his stuff, he really knows how to pitch and has very good command. Dombroski has posted some good numbers in the minors and after a tough 2024 season, he’s turned things around posting a 3.95 ERA across Double-A and Triple-A in 2025. Read more on Dombroski here.

23. Nick Monistere, OF

Level: Single-A DOB: 01/27/04

Monistere was selected by the Astros in the fourth round of the 2025 MLB Draft out of Southern Mississippi. He broke out during his junior season, batting .323 and leading the Sun Belt Conference with 21 home runs over 63 games. Primarily a second baseman in college, Monistere brings defensive versatility, with the ability to handle multiple positions around the field including shortstop. He also offers legitimate power at the plate, making him an intriguing offensive prospect with impact potential. He had some struggles following the draft but it was limited experience in Fayetteville.

24. Jose Fleury, RHP

Level: Triple-A DOB: 03/08/02

Fleury was signed during the 2021 international signing period for just $10,000, but could be another diamond in the rough for the Astros. As a 20-year-old, he dominated the DSL posting a 1.42 ERA with 4 BB/60 K in 38 innings. He has a really good changeup, which Baseball America ranked as the best in the system, and that he pairs with a low to mid 90s fastball. In 2023 he put up some gaudy numbers racking up 139 K in 98.2 innings with a 3.65 ERA. Fleury dominated early this year in Double-A but missed time due to injury and eventually earned a promotion to Triple-A where he struggled a bit. The changeup is legit weapon though.

25. Jase Mitchell, C

Level: Rookie DOB: 09/30/06

Mitchell was selected by the Astros in the seventh round of the 2025 MLB Draft and signed for $797,500, more than $500,000 over slot, after opting to forgo his commitment to Kentucky. A physical, left-handed-hitting catcher, Mitchell brings impressive raw power and a strong throwing arm behind the plate. He’s also considered a solid receiver defensively. With his combination of tools and upside, Mitchell has the potential to rise quickly through the Astros’ system and climb prospect rankings in the coming years.

26. Juan Bello, RHP

Level: High-A DOB: 04/06/04

Bello, acquired by the Astros in the Pressly trade, was originally signed by the Cubs in 2022 and made a quick rise to full season ball in 2024. In 2024, the right-hander posted a 3.21 ERA with 91 K in 89.2 innings. He did this at 20-years-old making 22 starts. Bello is a young athletic right-hander who has a really good curveball that he mixes with a low-90s fastball. Bello pitched in High-A Asheville in 2025 and performed well posting a 3.70 ERA with 66 K in 65.2 innings before his season ended due to injury.

27. Juan Sierra, OF

Level: Rookie DOB: 12/08/05

Sierra didn’t come with the typical large bonus that you see international prospects command, signing for just $67,500 in 2023. But he has progressed through the system and made it stateside last year. The 20-year-old hit .289 with a .804 OPS in 2025 for the FCL Astros. Sierra is well built at 6’1″ and 205 lbs. He has a simple swing that allows him to make contact without having to jeopardize power. Sierra also possesses a big arm, the prototypical fit for right field. 2026 could be a huge year for him as he makes his way to full-season for the first time.

28. Andrew Taylor, RHP

Level: High-A DOB: 09/23/01

The Astros nabbed a tall right hander in Taylor, who stands at 6’5″ and 190 lbs, with their compensation pick for losing Carlos Correa. Taylor has a low 90s fastball but generates a ton of swings and misses with high spin rate and carry, which is throws the majority of the time. The righty had an impressive college career for Central Michigan posting a 2.45 ERA with 261 K in 195 innings. Taylor also possesses a solid changeup and two other breaking pitches. Taylor pitched in Asheville in 2025 and had his best year posting a 3.39 ERA over 58.1 innings. Read more on Taylor here.

29. Sami Manzueta, INF

Level: Rookie DOB: 08/21/08

Manzueta was signed by the Astros in January of 2025, at just 16 years old for $847,500. He played in the DSL in 2025 and performed well with a 109 Hit+, which was the highest of any 16-year-old. This was boosted by his excellent 14% barrel rate, which was the highest of 16-year-olds listed on BA. He also had an impressive 87% contact rate in the zone and a 90th percentile exit velocity with 102 MPH. The raw stats came out to 9 doubles, 5 home runs and more walks than strikeouts in 46 games in the DSL. He might end up at second or third but his bat will be what carries him through the system.

30. Cole Hertzler, RHP

Level: Single-A DOB: 06/21/03

Hertzler was drafted by the Astros in the 5th round of the 2024 MLB Draft out of Liberty University. Hertzler has pitched limited innings due to injury but has dominated hitters in Single-A with a four pitch mix. In 21 professional innings, he has a 1.29 ERA with 28 strikeouts. His fastball sits in the low to mid 90s and can tough 96 MPH. Hertzler’s best secondary pitch is his slider that has continued to progress. His also added a changeup and curveball. He needs to get healthy but could take off in 2026.
