Blake Street Banter Team | August 22, 2025

Today kicks off the BSB Top 50 series where we drop the biggest available Rockies prospect list, based on the opinions of our prospect fanatic staff. This year, we are rolling out our top 50 with a handful of honorable mentions featured at the end of this initial post.

Overall, the Rockies system has failed to lock themselves in as a top tier prospect pipeline despite several consecutive losing seasons, including 6 consecutive top 10 picks and a handful of seller-oriented trade deadline. However, lost in translation because of top-heavy disappointments, the Rockies have stepped up their ability to build out the depth of their system, on display in these first few posts.

Leaving many of the following honorable mentions

Honorable Mentions

RHP Angel Jimenez

There is one thing Jimenez excels at and it is throwing hard. At one point in 2025 reaching 100 MPH, you will consistently see the right-hander sitting in the upper-90s. He is lacking reliable secondaries at the moment, but at 22 years old he has time to develop them. On the season, Jimenez has a 4.42 ERA across 15 starts.

2B Roynier Hernandez

Hernandez is the epitome of a hit-first player. Batting .299 on the season, the left handed hitter always puts the ball in play, striking out only 14% of the time, leading to a near .300 average on the year. More often than not he makes contact, boasting a stellar 88 contact%. His lack of power hurts his projection–especially with how necessary it is to reach MLB–but his plus contact will carry him through the minors and make him a potential role player.

3B Warming Bernabel

Bernabel fell off prospect radars following a disappointing 2024 season and just okay start to 2025 following a move to 1B. However, Bernabel started his MLB career blazing hot, even winning MLB player of the week following his debut. His success at the MLB level could make him deserving of top prospect status, but his high chase tendencies and low exit velocities don’t fall in line with traditional evaluation metrics. However, he keeps proving us wrong, which is entirely welcomed.

RHP Fidel Ulloa

A 2024 7th rounder from LSU, Ulloa is lighting up his first season in the pros as a reliever. A 1.70 ERA across 47.2 innings pitched while striking out over 30% of batters draws your attention while a mid-90s heater and power breaking ball hold it. While ranking relievers on a top prospect list is difficult, Ulloa is rising quickly through the minors as a legit relief prospect.

LHP Carson Skipper

After a 2024 breakout where Skipper struck out 79 batters in 58.2 innings, he was poised for more success in 2025. So far this season he has a 2.75 ERA while making it up to Triple-A. Skipper sits in the high-80s with his fastball, but his exaggerated over-the-top delivery manages to fool competition every step of the way. As he’s progressed through the minors, Skipper’s whiff rates have declined but his command has remained intact and he’s a likely big leaguer.

C Matt Klein

Drafted this year in the 6th round, Klein is yet to make his professional debut. However, while in Louisville he showed intriguing potential with the bat, slashing .310/.431/.509 with five home runs in the 2025 season. His contact numbers are even more promising when you see his 87.6 zone contact%. There’s strong exit velocities here but matched with his high groundball rate, Klein doesn’t have a totally clear offensive profile; he could breakout in the pros or remain a line drive oriented player.

INF Braylen Wimmer

Wimmer began his career with Fresno older than league average but tore the Cal League up with a .285/.362/.435 slash line with 14 home runs and 34 stolen bases. With proper adjustments to his swing and approach, Wimmer has one upped his 2024 campaign with a .305/.375/.494 slash line with 17 home runs and 31 stolen bases between High-A and Double-A, all while playing all over the field. Wimmer doesn’t necessarily have one single “wow” tool that would put him high on top prospect lists, but he plays the game hard and his numbers show for it. Expect for him to keep producing and work his way into the top 50 by end of season.

1B Tanner Thach

Drafted this past July, there weren’t many prospects with as much power upside available on day 2 than Tanner Thach. He has a strong swing built to elevate baseballs, and showed promising exit velocities in college. There are concerning chase tendencies, and he just hit 12 home runs in the 2025 season. However, Thach has a good swing and good coordination to make contact.  Nonetheless the bat is projectable, and he impressed the Rockies enough to have an end of season call up to Single-A. His bat can easily break out with his potential power input, making Thach a name to look out for.

RHP Lebarron Johnson Jr.

Out of every prospect in the Rockies organization, Johnson might have the most Major League ready arsenal and his likelihood of getting at least a bullpen gig is high. Johnson boasts a mid-90s sinker that gets up to 99 MPH, a wipeout-bat-missing slider, and an occasional changeup which all have steep downward movement, inducing ground balls at a solid rate. However his polished repertoire can only do so much with his presently poor command; he is walking nearly 15% of batters on the season, and it has only gotten worse as the season has progressed. Still, Johnson has power stuff that will continue to get him looks.
