MiLB Top 10 Prospects - Week Five
Tim Kanak brings MLB DW members 15 prospects to watch from all of the minor league action in Week Five
Hey friends, welcome to my weekly prospect report, now only found with an MLB Data Warehouse subscription! The goal of this column is to give you the most fantasy-relevant prospect information throughout the last week, all in one place. The format of this weekly prospect report will be a run-through of my top 15-20 prospects of the week, with a goal to get at least three prospects at each level (DSL - AAA).
I will try my best to highlight new prospects every week, rather than repeat names, unless the repeat is so warranted that I just can’t help myself.
This should not be seen as a weekly stash rankings, but as a ranking of top performers each week through all levels. My updated top 150 rankings can currently be found on MLB Data Warehouse, and thanks to Jon, we will now have regularly updated fScores throughout the year.
It should also be noted that THIS WEEK the fScores were updated, so these are all updated fScores now.

NOTE: Rookie status is determined by 130 ABs, or 50 IPs at the Major League level.
NOTE: All stats from Sunday, April 26 - Saturday, May 2 2026
T-10 Prospects
1. 2B/SS John Peck (Tigers) - AA
ETA: 2027
Comp: Zack Gelof
Prime Skills: Peck has shown a solid power and speed combo for a probable second baseman, but has strikeout problems and a below average contact tool. He’s shown the ability to get to optimal line drive angles though and the seventh rounder had a fantastic week with 8 extra base hits, 4 homers and 3 steals. It’s hard to top that week, but overall a 2% walk rate and 31% K rate is incredibly dangerous. He’s incredibly aggressive and runs high BABIPs due to the ability to get to consistent line drives and has reached up to 110 mph exit velocities with plus defense. He profiles as a utility player long-term but could go on some nice runs thanks to his ability to get to doubles.
Hitter Tool Grades:
Hit: 30/40
Plate Approach: 25/30
Power: 40/45
Speed: 55/55
Prospect Rank: Top 500
2. OF Lazaro Montes (Mariners) - AA
ETA: Early 2027
Comp: Shades of an OF Matt Olson
Prime Skills: Big strong kid with fantastic power from the left side and a solid eye. The power is up this year from last year, but he is also striking out quite a bit more as the hit tool seems to be getting worse from a contact standpoint (62.9%), while the angles are slightly above average (15% barrel rate in 2024). He hits the ball very hard with a reported 116 max EV and a 106.3 90th percentile EV this season and smashed 58 extra base hits in 131 games. Montes had a ridiculous week capped by a 3 homer game where he smashed one 118 mph, netting him 6 extra base hits and 5 bombs on the week.
Hitter Tool Grades:
Hit: 30/40
Plate Approach: 40/45
Power: 65/70
Speed: 35/30
Prospect Ranking: 65
3. OF Joseph Sullivan (Astros) - AA
ETA: Late 2026
Comp: Trent Grisham mashed with a more twitchy PCA mechanics and speed
Prime Skills: Sullivan is a seventh rounder out of South Alabama from 2024 with a lot of good stuff under the hood as some of the stats here look pretty extreme. Sullivan finished with an incredibly rough second half slashing .191/.357/.264 after a fabulous first half, but overall he’s basically the Astros version of Emmanuel Rodriguez with a big time three true outcomes approach with plus speed. He hits the ball hard with a 112.2 max EV at the 2024 draft combine and a reported 108 90th percentile EV in 2025. The contact rates are only below average, but the angles are also below average and he doesn’t swing enough. Sullivan was a faller in the fScores despite putting up some pretty sexy back of the baseball card stats early in the season, meaning his under the hood metrics and his production are just beginning to align. Sullivan had a fantastic week with 5 extra base hits, 3 bombs and 2 steals - doing a bit of everything.
Hitter Tool Grades:
Hit: 30/40
Plate Approach: 35/50
Power: 55/60
Speed: 60/60
Prospect Rank: 112
