HOUSTON – Shortstop Xavier Neyens, taken by the Astros with the No. 21 overall pick in this year’s MLB Draft, debuted as the Astros’ No. 3 prospect in MLB Pipeline’s midseason Top 30 Prospects re-rankings. He was behind second baseman Brice Matthews (No. 1) and outfielder Jacob Melton (No. 2), both of whom made their Major League debuts this year.
Catcher Walker Janek, who was taken by the Astros in the first round of last year’s Draft out of Sam Houston, remained at No. 4 in the re-rank, with right-hander Miguel Ullola moving up a spot and into the Top 5 after posting a 3.70 ERA in 82 2/3 Triple-A innings with 103 strikeouts and 63 walks (1.45 WHIP).
Neyens, who’s yet to be assigned to an affiliate, led his high school team in Mount Vernon, Wash., to a state title this season, hitting .456 with eight home runs, 10 doubles, 27 RBIs and 49 runs scored in 28 games. There are some swing-and-miss concerns with Neyens, but MLB Pipeline cites an “outstanding approach” that helped lead him to hit with power to all fields in high school.
Here’s a look at the Astros’ top prospects:
- Brice Matthews, 2B (MLB No. 98)
- Jacob Melton, OF
- Xavier Neyens, SS
- Walker Janek, C
- Miguel Ullola, RHP
Biggest jump/fall
Here are the players whose ranks changed the most from the preseason list:
Jump: Bryce Mayer, RHP (Preseason: 30 | Midseason: 11) – Mayer, a 16th-round pick last year out of Missouri, began the season at Single-A Fayetteville and has already earned a pair of promotions, taking him to Double-A Corpus Christi. He posted a 3.22 ERA in 14 games (12 starts) combined for Fayetteville and High-A Asheville before reaching Corpus Christi on July 5. In 26 innings with the Hooks, he has a 4.85 ERA and a 1.23 WHIP with 10 walks and 34 strikeouts.

Fall: Luis Baez, OF (Preseason: 12 | Midseason: 22) – Ranked No. 2 among Astros prospects on the preseason list in 2024, Baez, who signed for $1.3 million out of the Dominican Republic in 2022, is slashing .200/.261/.267 with one homer and seven extra-base hits in 165 at-bats at Double-A this year. He didn’t make his full-season debut until early June because the Astros wanted him to focus on some areas he could improve upon defensively without worrying about game performance.
