Blake Street Banter Team | August 26, 2025
We officially break into the BSB Top 50 today, with several international signings headlining the depth of the system. A pair of 2024 draftees have seen their stock slip slightly but continue to hold steady with a late season push.
Most notably, Wilder Dalis carries plenty of helium into next season as one of the best overall MiLB performers in the system.
#50: INF Blake Wright
Wright was an underslot signing in the 2024 draft to help the Rockies afford to sign both Charlie Condon and Brody Brecht who combined for around $450,000 overslot (Wright was signed $430K underslot). While his $250,000 signing bonus tempered expectations on the 4th round pick, Wright is a very solid prospect. Coming out of Clemson, Wright was heralded for his steady leadership, reliable defensive ability, bat to ball skills, and ability to lift the baseball.
In the pros, Wright has not torched the lower minors as expected but his 108 wRC+ between Single-A Fresno and High-A Spokane suggest he will be a force in the system with a chance to earn a utility infield role given his playing time at 3B and 2B.
#49: RHP Sandy Ozuna
Ozuna has largely flown under the radar as a Rockies prospect, in part because he has barely cracked the 70 innings mark in his career despite signing in 2023. Ozuna carries a pair of hellacious offerings with his fastball capable of getting into the upper-90s already despite plenty of room to continue growing. Ozuna’s slider sits in the mid-80s and has plus characteristics.
Ozuna’s command and pitchability have been trending in the right direction when he’s been able to take the mound. If he can string together a season of good health, Ozuna could rise well into the Rockies top 30.
#48: SS Wilder Dalis
Signed back in 2023, Dalis has been a secret the Rockies have been trying to keep from the world. After a measly 69 wRC+ his first pro season, nobody batted an eye at Dalis. However, a strong 2024 DSL campaign earned him a 2025 promotion stateside, and this season he’s putting up his best numbers yet, slashing .340/.425/.511 with four home runs across the ACL and Single-A.
Being a switch hitter, Dalis excels from both sides of the plate. He has a bigger-than-life swing, and his presence in the box is much larger than his 6-foot, 172 lbs stature would suggest. Good swing decisions and a disciplined approach are also reasons why he is excelling so far in the lower levels. Dalis could stick at shortstop, making him all the more valuable.
#47: RHP Roberto Salas
In 2024, Salas made his professional debut for the Diablos Rojos del Mexico of the Mexican League at just 16 years old; 14 years younger than league average. Salas even shared the field with 8x MLB All-Star Robinson Canó and 2020 NL Cy Young Trevor Bauer. The Rockies signed him that offseason.
So far in 2025, the Mexican right-hander is lighting up the DSL. Through 36.2 IP, Salas has only one earned run which is good enough for an unreal 0.25 ERA. He has three exciting offerings; a fastball that sits 88-90 MPH, a mid-70s curveball with good shape, and a tumbling low-80s changeup that drops down out of nowhere. Best of all he has almost-perfect command on all three pitches, having only walked 2.3% of batters he’s faced this year. Though he doesn’t throw very hard, he’s still only 17 and listed at 157 pounds, so expect to see a couple of ticks added to his fastball as he matures.
#46: UTIL Derek Bernard
Derek Bernard, a former New York prep player, moved to the Dominican Republic as a teen to sign into pro ball sooner, joining the Rockies organization at just 16. Four years later, he’s making a name for himself in Low-A Fresno. Bernard has experience at 2B and in the outfield, but may be a full-time outfielder going forward.
After a slow start following his May promotion, the versatile 20-year-old has found his rhythm at the plate. Over 60 games, he’s compiled an impressive .820 OPS with a 130 wRC+, driven by a smooth left-handed swing. Perhaps even more promising is the fact that he’s walking in nearly 12% of his plate appearances, an encouraging figure for a player with limited experience. Bernard is still a few years away from the majors, but his performance this season has firmly placed him on the prospect radar.
#45: RHP Jack Mahoney
In 2024, Mahoney burst onto the scene for the Rockies and posted a 3.90 ERA across 120 innings pitched between Single-A and High-A. Most impressive of all is that he walked only 6% of batters in that span. Meanwhile, in 2025 he has a 5.92 ERA in Double-A, more than a run worse than expected.
The right-hander boasts a fastball that sits 94 MPH, mixing in a slider and changeup that both complement each other, all while having a good feel for the three. Mahoney lacks a true above average pitch, and his command isn’t quite precise enough to fool more advanced hitters which makes it difficult for him to pick up strikeouts, having his strikeout percentage go down by nearly 6% in just one year. His pitchability still gives him projection to be a back end starter, though a bullpen transition has become a possibility.
#44: C Cole Messina
Messina was a collegiate titan, swatting 38 homers between 2023-24 for South Carolina and recording a 149 wRC+ in his junior pre-draft season. Not only was Messina an offensive juggernaut but he was the Gamecocks’ everyday catcher with solid acumen in each facet of catching.
Messina has been slow out of the gate with just a 99 wRC+ and only 7 homers in High-A Spokane, but he has managed to run a very respectable 11.2 BB% and 16.7 K%. If the power can return to Messina’s game, the Rockies will have a formidable catching prospect on their doorstep.
#43: RHP Marcos Herrera
Prior to 2025 Herrera has never gone a season with an ERA under 4.00 and has struggled getting strikeouts. However, in 2025 the right-hander currently sits at a 3.63 ERA and is running his highest career strikeout rate.
This success can be attributed to unlocked fastball velocity. The 20-year-old consistently dials it up to the upper-90s, giving it potential to be a double-plus offering. He pairs his fastball with a high-spin slider that induces whiffs as well as an underdeveloped changeup. The caveat is a lack of control. His command is probably worse than advertised, as he consistently misses both in and out of the zone. Leading to hittable pitches and laborious at-bats. However, Herrera is still very young so time will tell whether this is a true concern or not. The upside here matches nearly any arm in the system.
#42: OF Cristian Arguelles
Signed in 2024 out of Venezuela, Arguelles is amidst one of the best seasons in DSL history. He’s currently slashing .422/.528/.652, good enough for a wRC+ of 198. His average of .422 is also on pace to be the highest in the Minor Leagues since at least 2006.
Arguelles has a special bat-to-ball ability. His smooth lefty swing works through the zone efficiently, and his plus discipline has led to amazing results. While he will likely never have great raw power due to his smaller frame, the lefty has barreled out five home runs this season. Offensive numbers in the DSL should always be taken with a grain of salt, but numbers like Arguelles’ are too intriguing to ignore and he should remain an average or better pure hitter as he progresses stateside.
#41: 1B Aidan Longwell
Since joining the Rockies organization in the 2023 draft, Aidan Longwell has done nothing but rake. The 23-year-old first baseman has carried that momentum into 2025 with Spokane, ranking in the top 10 in the Northwest League in batting average (.286), home runs (15), and OPS (.836). He also leads the league in doubles (31) and RBIs (69), showcasing both his power to the gaps and the ability to leave the yard.
With the long-term future at first base in Colorado being a bit of a question mark, Longwell is a name to watch within the system as a promising pure hitter with some budding power.
