The division reports debuted last year. The goal of this article series is to provide a quick overview of all dynasty-relevant information from each division. Each team has multiple levels each containing plenty of impactful prospects which can feel impossible to keep up with. This article series, which will be updated once per month, will help dynasty managers stay up to date on performances, injuries, promotions, and more. New this season is the inclusion of tiers in the rankings. Next to their rank, each prospect is assigned a tier. The tier range is 1-5.
- Tier 1: A potential difference-making dynasty prospect. Somebody who would rank in the top-20ish prospects for dynasty baseball
- Tier 2: A still very good dynasty prospect who holds plenty of value. This prospect would typically rank in the 21-75 range
- Tier 3: A mid-tier prospect who could be valuable but has questions and concerns present in his profile ranking in the 76-150 range
- Tier 4: A prospect who is worth knowing, but is reserved for deeper leagues. This prospect would rank 151-250
- Tier 5: The rest of the prospects fall into Tier 5
This article details all of the changes dynasty managers need to know about prospects from the Astros. The goal is to help dynasty managers stay updated on the latest information with in-depth looks at each specific team! Each division will come with a monthly update that readers can look forward to.
This list features prospects not currently in the Majors.
Notable Prospect Promotions and News
- With the 21st pick of the MLB Draft, the Astros selected Xavier Neyens, a powerful prep bat who has an aesthetically beautiful swing. He was drafted as a shortstop, but is almost certainly not a shortstop. It’s more likely he winds up at third base or in the outfield. His power is noted, but it does come with some hit tool concerns. The power is very real, and he’s gotten high marks for his approach, though there may be some swing and miss as he enters the pro ranks.
- From the July list, Jacob Melton was not there because he was on the Astros roster. Since then, both Brice Matthews and Jacob Melton have returned to Triple-A with their prospect status intact. Matthews drops a bit because of his home/away splits in the PCL, and Melton rejoins the list at number two after returning from injury and being optioned.
Notable Prospect Performances
- The incomparable Doc Eisenhauer gave some hype towards Joseph Sullivan, hinting that he could be in for a big jump in prospect status. That’s more than enough for me to give him a shout here. Sullivan had three homers in July to go along with 10 stolen bases and hit .246. For the season, he has 17 homers and 38 stolen bases. His average is just .227, but the belief is that he has hitting skills that outpace that mark.
If you missed out on the Konnor Griffin rocket ship, this is your last warning on #Astros' Joseph Sullivan – a dynamic TOP-20 prospect as far as I'm concerned!
The kid is flashing 18 HR/38 SB in 88 games over his first full pro season, but nobody seems to care.

- Miguel Ullola is boasting a 28.2 percent strikeout rate for the season, which translates to 103 strikeouts in 82.2 innings. That does come with a 17.3 percent walk rate. The walks are very much there, but in July Ullola struck out 28 batters in 18.2 innings. There were 15 walks. Clearly the stuff plays, and if he can reign in the command then his stats are going to turn into absolute silliness.
Miguel Ullola dominated this May earning Pacific Coast League Pitcher of the Month honors. In 5 starts, Ullola posted a 1.17 ERA with 34 K in 23.0 IP.
Ullola is off to a hot start in June, tossing 5.0 scoreless innings in his first start of the month and racking up 7 strikeouts. pic.twitter.com/oxqVanslLm
