Big prospect and dynasty content stream starting here! Tim Kanak (@fantasyaceball) has done a full re-rank of his top 150 prospects. Diving DEEP into these guys and giving us full scouting reports and scores. It’s a ton of work, and we love that Tim is doing it all right here at MLB Data Warehouse. He’s truly one of the best in the industry at doing this stuff.
The app has also just now been updated with this new #1-#150.
Find that here:
That makes it searchable by player or organization. It’s an incredible amount of data and write-ups all in one powerful app.
Let’s get into it! We’ll go 25 at a time.
Top 150 Prospect Rankings Update (Memorial Day, 2026):
These prospect rankings are based on FANTASY value, not on real life value. Considering such, hitters generally weigh a bit heavier for me due to the injury risk and higher volatility of prospect pitchers. Proximity to the majors is also prominent in the equation, though these rankings are taking a longer-term / dynasty look on these guys (think of it more as a 5 year plan).
Rather than getting into writing little bios on all of these hitters, I’ve decided to keep my rankings simple by providing the 2026 stats of each player across all levels, the player’s fScores (which can be found only on MLB Data Warehouse), a player comp, a small blub on the player’s prime skills for fantasy including my tool grades / pitching arsenals and an explanation of my ranking that may include trending data.
Please note these rankings are the result of months of work from using available data via MLB Data Warehouse, the fScore algorithms developed by myself (and coded by Jon Anderson), regular in-person scouting (Florida based), writing weekly prospect performance columns and weekly performance podcasts and regular film review; I have provided my personal comps for each prospect (for fun - note: comps may be based on mechanics, body type, pitching arsenal or similar skills & box score style) and how I generally think each prospect will perform once in the majors over the next five or so seasons.
Additional in-season note: The statistical references will vary as I’m writing this article in-season over the course of a two week time period. Look at the right side of the date slider to see the dates in comparison to each other when referencing multiple players.

NOTE: Rookie status is determined by 130 ABs, or 50 IPs at the Major League level - rather than including time on roster.
126. OF Spencer Jones (Yankees)
ETA: Debuted
Comp: Joey Gallo w/ more speed
Prime Skills: He’s huge at 6’ 6” and has ridiculous power potential with decent speed to boot. He has a ton of sneaky speed to go along with the huge power potential, but the swing has some massive holes in it and has gotten progressively worse (73.2% contact rate in 2023, 61.6% in 2024 and 59.6% in 2025). The contact part of the hit tool is bad, but the quality of contact is very good and is what drives his fScore hit ranking to a 99. Jones notched 59 extra base hits through 116 games in 2025 and 20 in 38 games in 2026, so there’s bound to be some electric production, even if volatile. The 150 XBH+ is literally maxed out with Jones - buy at your own risk, but there is stuff to like here if he can hit enough. His plate approach is actually not even that bad, he doesn’t overly chase, he just overly misses. The exit velocities are a stuff of legends.
Hitter Tool Grades:
Hit: 25/30
Plate Approach: 35/40
Power: 70/75
Speed: 60/60
Ranking Explanation: Kind of like Charlie Condon, it’s the off-speed, not the breakers that destroy Spencer Jones. He actually hits sliders and sweepers better than fastballs. Against curves, change ups and splitters this year he is hitting .122/.217/.244 with a 48% contact rate. He’s a huge gamble and there’s probably a 25% chance of him paying off, but he’s worth gambling on in some leagues just in case he hits. He has the highest range of outcomes of anyone on this entire ranking.
Previous Rank: 73
127. 1B/OF James Tibbs III (Dodgers - AAA)
ETA: Mid/Late 2026
Comp: Mike Yastrzemski
Prime Skills / Player Notes: Tibbs has shown ridiculous power this year by accessing great power angles and increasing his exit velocities across the board. Tibbs has become a barrel and sweet spot master that kind of reminds me a bit of a better Colby Thomas angles ability, but the contactability is still a little iffy and unlike my comp of Mike Yastrzemski he can hit lefties nearly as well as righties, so the platoon risk isn’t there.
Hitter Tool Grades:
Hit: 40/45
Plate Approach: 50/55
Power: 60/60
Speed: 45/45
Ranking Explanation: There might be more than a 50% chance Tibbs is traded again prior to playing for the Dodgers. He’s already been traded from the Giants and Red Sox and we have to keep in mind this power burst is happening in the PCL. The Dodgers have a ridiculous number of prospect OFs and many are better than Tibbs, though at lower levels (De Paula, Sirota, Quintero, Hope) and there’s also Davalan, George and more. Tibbs has been playing some first, which might be his best bet to the bigs, but Freddie Freeman is signed through 2027, so he would be waiting another year and a half at least. I think he’s more of a fourth OF in this org, but in another organization with full playing time his peak might be .230-.250 with 23-28 homers and a decent walk rate, but also a hefty-ish K rate. The floor on Tibbs is higher than Spencer Jones, but the ceiling is so much higher that Jones gets the nod for the dart throw.
Previous Rank: Top 200
128. 2B/SS Seaver King (Nationals)
ETA: Late 2026
Comp: Whit Merrifield
Prime Skills: King has a wide open stance that generates more power from his smaller frame than you would expect that will likely translate more for doubles than homers in the majors. He is aggressive in the zone and should run high averages. He definitely looked more built this spring and the exit velocities in his AAA small sample size show this with a very nice 108 90th EV so far. He was rough on the bases in AA this year after stealing 40 bags and only caught 5 times in 2024 and 2025. For a guy with a low K rate, he chases a bit too much, but his plate approach is still likely average or better. The contactability is solid, but he hits the ball on the ground too much and the best case scenario is a high line drive, doubles profile like in AA earlier this year, because he has an interesting opposite field approach that will result in lower homers totals. King has 23 extra base hits in 44 games this year.
Hitter Tool Grades:
Hit: 45/55
Plate Approach: 45/55
Power: 45/45
Speed: 65/70
Ranking Explanation: King is above average across the board in the hit tool, plate skills and power department with double plus speed. King needs to work on increasing liners and getting the ball off the ground to optimize his portfolio as a double, speed first hitter. He has a decent amount of upside as the batting average should be better considering he has a plus hit tool. Peak King looks like a .260-.280 hitter with 10-15 homers and 25-30 steals.
Previous Rank: Top 200
