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.


Please subscribe to the Fantasy Aceball podcast and MLB Data Warehouse podcast feeds or on YouTube (@TheTimkanak) and also follow me on X (@fantasyaceball) for more fantasy goodness!

NOTE: Rookie status is determined by 130 ABs, or 50 IPs at the Major League level.

NOTE: All stats from Sunday April 12 - Saturday April 18 2026

***AAA started a week earlier, we discussed them last week on the Week 1 podcast.


T-10 Prospects

1 | SP Miguel Sime Jr. (Nationals) - A

ETA: 2028

Comp: Jacob Misiorowski-ish arsenal coming from a righty CC Sabathia delivery

Prime Skills: I can’t believe Sime lasted until the fourth round in the draft last year; my first look at him in person in the Spring Breakout game was enough to get me on board. Sime is built like a brick house at 6’4, 235 pounds The dude has a ridiculous fastball hitting up to 102 mph and blew away Tai Peete and JJ Wetherholt on the fastball in the breakout game. He has a nice 11-5 curveball that was his primary strikeout pitch this week when he racked up 9 strikeouts with only 1 walk in 4 no-hit innings. He almost reminds me of Alfredo Duno, but as a pitcher body type-wise.

Arsenal Grades:

  • FA (98-102 mph): 70/70

  • CU (80-84 mph): 50/60

  • CH (85-88 mph): 30/40

  • Command: 30/40

Prospect Rank: Top 200


2 | 2B Manuel Pena (Diamondbacks) - AA

ETA: Mid 2027

Comp: Brandon Lowe

Prime Skills: Pena is showing an elite power tool for a second baseman with a 110.6 max EV this spring where we have some statcast data on him and pairs this with a slightly above average hit tool based on a slightly below average contact rate, but the ability to get to plus power angles. There’s not much speed here, but a middle infielder with a solid hit tool and plus power is an interesting play. Pena hit .575 this week with 9 extra base hits and 5 bombs, giving him a ridiculous 8 homers in 13 games to start the season. He does not walk at all, but it should be noted he has equally mashed lefties vs. righties as a left handed hitter.

Hitter Tool Grades:

  • Hit: 40/50

  • Plate Approach: 40/40

  • Power: 60/60

  • Speed: 40/40

Prospect Rank: Top 350
