Astros Future’s 2026 Astros Minor League Postseason All-Star Team pointed to plenty of talent buried in Houston’s system, but four names stand out as the ones most likely to matter in the majors by 2027.
Two of them are right-handers already on that kind of track in Bryce Mayer and Jackson Nezuh. One is a catcher with numbers that are hard to ignore in Jason Schiavone. The other is Pascanel Ferreras, a versatile infielder who keeps forcing his way into the conversation.
Bryce Mayer looks like the safest bet to reach Daikin Park first.
The right-hander has now been named Astros Pitcher of the Year in back-to-back seasons, and he backed up his 2025 work with an even stronger 2026. Across 102 innings, Mayer posted a 3.53 ERA with 140 strikeouts and only 73 hits allowed.
His 12.4 K/9 led the Astros minor-league system. At Double-A Corpus Christi, he was especially sharp, putting up a 2.61 ERA with 100 strikeouts in 69 innings before moving up to Triple-A Sugar Land.
The numbers at Triple-A weren’t as clean. Mayer finished with a 5.45 ERA in 33 innings, but he still punched out 30 hitters in that span.
That kind of swing-and-miss matters, especially when the issue is command rather than stuff. Houston has dealt with pitchers in that lane before, and the organization tends to go to work on the problem quickly.
Jackson Nezuh may not have the same name recognition, but he’s not far behind.
At 24, Nezuh turned in a 3.83 ERA with 124 strikeouts over 103 1/3 innings, good for an average of 10.8 K/9. That doesn’t jump off the page quite like Mayer’s line, but it’s still the kind of strikeout production that plays at the highest level. His climb from Double-A Corpus Christi to Triple-A Sugar Land came after he posted a 3.97 ERA in Corpus Christi while striking out 44 batters in 37.2 innings.
Once he reached Triple-A, his ERA dipped against tougher hitters. If he develops into a fifth starter, swingman or sixth starter who can move between Houston and Sugar Land, that would give the Astros something they need: controllable pitching depth. Right now, that kind of depth matters even more because the system doesn’t have a lot of it.
Then there’s Jason Schiavone, and the stat line is loud enough to make people stop and stare.
“The 23-year-old catcher played 123 games and finished with a: .252 batting average, .391 on-base percentage and .531 slugging percentage”
Stats from MILB.com
He also added 26 doubles, 90 RBI and a 134 wRC+. And if that wasn’t enough, he hit 32 home runs and stole 32 bases.
It was the first time a primary catcher had reached those numbers in 45 years. For a catcher, that mix of power and athleticism is rare.
Schiavone’s rise through the system is moving fast, too. He advanced three levels in one season, the Astros kept challenging him, and he kept producing.
There are still real developmental questions, though, and they matter. The swing-and-miss remains part of his game, and catching in the majors is about much more than offense.
Receiving, blocking, game-calling and working with pitchers all factor in. He’s currently projected to arrive in Daikin Park in 2028, but his bat could push that timeline.
Pascanel Ferreras doesn’t have the same spotlight, but he keeps building a case.
He was the final pick of the 2023 Draft, and he opened 2026 in Double-A Corpus Christi, where he hit .263 in 30 games before earning a promotion to Triple-A Sugar Land. Once there, he looked right at home.
In 71 Triple-A games, Ferreras hit .305 with 24 doubles and 46 RBI. He finished the year at .294/.367/.450 with 29 doubles, nine home runs, 62 RBI and 11 stolen bases, along with a 116 wRC+.
Ferreras doesn’t appear headed to Houston as an everyday shortstop unless the Astros trade Jeremy Pena, but that’s not really where his value is strongest anyway. His ability to handle multiple positions makes him useful, and Houston clearly values that kind of player. As a versatile, inexpensive utility infielder who can still put together competitive at-bats, Ferreras brings a profile that can matter across a full season.

Astros Salary Trade Is Starting To Look A Lot More Complicated
The offseason deal that sent Mauricio Dubon to Atlanta for Nick Allen was always framed as a money-saving move for Houston, a way to trim the luxury tax bill while keeping the roster flexible. Allen gave the Astros a useful year anyway, handling multiple infield spots and finishing with a solid 1.3 bWAR, the kind of steady production that helps a contender survive the grind of a long season.
Mauricio Dubon, though, made the conversation more complicated from the other side. He turned into a significant piece for the Braves and helped fuel their postseason push, giving the trade a very different look than the one Houston probably imagined when it moved on from him. For an Astros front office that has tried to balance payroll concerns with winning, the deal now looks a little less like a clean financial maneuver and a little more like one that will keep drawing second-guessing.

Astros Already Face A Tough Ethan Pecko Decision
Ethan Peckos first month with the Astros has already given the club plenty to weigh as it looks ahead. The right-hander made his major league debut on Aug. 19, working 3 2/3 innings and allowing two earned runs, then kept bouncing between the rotation and the bullpen over his first eight appearances as Houston tried to sort out what kind of role fits him best.
What has stood out most is that the stuff has played differently depending on how hes used, with command issues and a modest strikeout rate making the evaluation tricky. Pecko has looked more comfortable coming out of the bullpen than taking a turn in the rotation, and that leaves the Astros with a familiar sort of pitching dilemma: whether to keep developing him as a starter or lean into the shorter outings that seem to suit him better.

Astros Have One Obvious Rotation Fix After That Brutal Exit
The Astros still managed to win the AL West, but the season ended with a harsh reminder of how thin the margin can be in October. After posting the worst record in postseason history and getting swept by the White Sox in the wild-card round, the focus in Houston has already shifted to the one area that looked most fixable: the starting rotation.
Among the names that make sense for a club trying to add stability without blowing up the payroll is a right-hander coming off a solid 2026 regular season and postseason run. He offers the kind of cost-conscious depth the Astros can actually work with, especially with his next contract expected to come in under a manageable price point, and that makes him a logical fit for a team that needs innings as much as it needs answers.
