With the Astros’ newly updated Top 30 Prospects list out, I figured it would be a good time to look at some of the prospects who have made the biggest jumps in 2026.
Every season brings breakout performances, unexpected risers and players who take significant steps forward in their development. This year has been no different, with several prospects going from relatively under-the-radar names to some of the more intriguing players in the Astros’ farm system.
Here are some of the prospects who have boosted their stock the most in 2026.
Jason Schiavone
The Astros selected Schiavone in the 11th round of the 2024 draft. Prior to the season he was unranked, but he has flown way top this year. After a down year in Fayetteville, he went on an absolute tear in Asheville batting .289 with 17 home runs and a 1.218 OPS. He also earned a promotion to Double-A where the numbers are down a bit, but still solid with a .742 OPS. Schiavone is an intersting hitter as he provides elite power, good plate discipline, but also some swing and miss. On top of the 23 home runs, he had drawn 80 walks in 91 games, though he has 133 strikeouts. The power is legit though and he has posted some elite exit velocities. Defensively, he is athletic behind the plate with improving receiving and a strong arm. He’s also thrown out 47% of base stealers in Double-A.
Albert Fermin
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. With his strong arm and solid instincts, he projects well at either position on the left side of the infield. He was highly touted but has been phenomenal since taking the field hitting .331 with 9 doubles, 5 home runs, 21 stolen bases and a 1.021 OPS in the Dominican Summer League. He’s moved up to a top 5 prospect.
Anthony Huezo
Huezo, the Astros’ 12th-round pick in 2023, was on this list to start the season but saw a nice bump this year. After a solid showing in 2025 between rookie ball and Fayetteville, Huezo took a huge step forward. Huezo was electric in Single-A at 20 years old posting a .856 OPS with 20 doubles, 14 home runs and 30 stolen bases in Single-A, earning him a promotion to High-A where he’s been solid through the first couple of weeks. Huezo has some big time tools, and while he strikes out a bit, his raw power makes up for it. Read more on him here.
Nick Potter
Potter was selected by the Astros in the fifth round of the 2025 MLB Draft after spending two years at the junior college level and one season at Wichita State. He had upside when the Astros drafted him but was unranked as we needed to see the conversion was closer to starter. So far, the transition has gone extremely well. Potter has posted a 2.12 ERA with 75 strikeouts over 63.2 innings this season. His combination of premium velocity and success as a starter has made him one of the more intriguing pitching prospects in the Astros’ system.
Jagger Beck
The Astros took a somewhat unconventional route after the 2024 draft, signing right-hander Beck out of high school as an undrafted player. Only getting a few professional innings, he was another prospect with upside but needed to get his feet wet in Fayetteville. he has taken to the challenge this year. The 19-year-old opened this season with his full-season debut in Fayetteville and has shown plenty of promise early on. Through 18 appearances, Beck owns a 2.97 ERA with 80 strikeouts over 69.2 innings pitched. He has gone from unranked to top 20.
