VALUCAST BUYS

AHEAD OF THE CURVE

The 40 best prospect buys by signal, not reputation · JULY 30, 2026

Source: ValuCast buy signal. Ranks prospects by model strength, momentum, buy window, and runway.

buy score = model strength + momentum + buy window + runway. Window closes at MLB debut; fresh signings surface once they have enough data.

Top 40 shown of 221 qualified · 2,900-prospect pool · 40 active-MLB call-ups excluded · the signal qualifies ~8% of the pool by design.

Form curves span up to 14 days within the current scoring era (re-based June 22); "All" shows the last 14 days. The Movers board measures change over its own shorter window; different window, different question.

1
Cam Caminiti ATL · P · A+ · 19y A rotation role is not supported by the current line; the floor is organizational depth or a low-leverage bullpen assignment; nothing in the profile gives hi...
61.6 Still In The Buy Window
2
Eli Willits WSN · SS · A+ · 18y The line does not show a second offensive strength at the same level; he forces pitchers into the zone and takes the free pass.
61.1 Young Runway
3
Brady Ebel MIL · SS · A · 18y He is 18 in Single-A over 419 PA, so confidence is low.
60.9 Young Runway
4
Braylon Payne MIL · CF · A+ · 19y He punishes mistakes often enough to carry the bat; better pitching can keep the power in the dugout with empty swings.
60.2 Still In The Buy Window
5
Johnny King TOR · P · A+ · 19y He is 19 in High-A over 76 IP, so confidence is low; he has a dependable way to finish hitters.
59.7 Still In The Buy Window
6
JoJo Parker TOR · SS · A · 19y The walks create an everyday path, but the present outcome is a reserve; he forces pitchers into the zone and takes the free pass.
59.5 Still In The Buy Window
7
Ethan Holliday COL · SS · A · 19y The sample covers 152 PA in Single-A, so confidence is low.
59.4 Still In The Buy Window
8
David Shields KC · P · A+ · 19y Nothing in the profile gives him a dependable way through a lineup yet; the failure point is the strikeout-to-walk result, which does not support a firm star...
59.2 Still In The Buy Window
9
Leo De Vries ATH · SS · AA · 19y The risk is a broad but ordinary offensive line without one result that forces an everyday role; he is contributing across contact, walks and damage rather t...
59.2 Still In The Buy Window
10
Justin Gonzales BOS · RF · A+ · 19y He forces pitchers into the zone and takes the free pass; the risk is that better pitching reduces the walks without another loud offensive result replacing...
59.0 Still In The Buy Window
11
Nathan Flewelling TBR · C · A+ · 19y The miss rate keeps that power from showing up consistently.
58.8 Still In The Buy Window
12
Josiah Hartshorn CHC · 1B · A+ · 19y He is 19 in High-A and Single-A over 405 PA, so confidence is low; pitchers have to come into the zone, and he makes those pitches hurt.
58.4 Still In The Buy Window
13
Ryan Sloan SEA · P · AA · 20y The strike throwing is the reason to keep him on a starter track; he does not finish enough hitters to own the middle of a rotation.
57.7 Still In The Buy Window
14
Chase Harlan LAD · 3B · A+ · 19y He is contributing across contact, walks and damage rather than leaning on one result; no single result is loud enough to carry the bat through regression el...
57.4 Still In The Buy Window
15
Kash Mayfield SDP · P · A+ · 21y The sample covers 53.3 IP in High-A, so confidence is low.
57.0 Still In The Buy Window
16
Boston Bateman BAL · P · A+ · 20y Rotation lean; the strike throwing decides whether it holds; he misses enough bats to keep a rotation outcome open.
56.9 Still In The Buy Window
17
Eduardo Quintero LAD · CF · A+ · 20y The sample covers 370 PA in High-A, so confidence is low; he works deep counts and gets on base.
56.8 Still In The Buy Window
18
Eric Hartman ATL · CF · A+ · 20y The sample covers 413 PA in High-A, so confidence is low.
56.5 Still In The Buy Window
19
Kade Anderson SEA · P · AA · 21y Hitters have to earn their way on, and he can finish them; nothing in the line points to a weakness yet; the next level is the real test.
56.5 Model Conviction
20
Juneiker Caceres CLE · RF · A+ · 18y He is 18 in High-A and Single-A over 280 PA, so confidence is low.
56.0 Young Runway
21
Seth Hernandez PIT · P · A+ · 20y The sample covers 74 IP in High-A and Single-A, so confidence is low; he misses enough bats to keep a rotation outcome open.
56.0 Young Runway
22
Sebastian Walcott TEX · - · AA · 20y Everyday power ceiling; the current floor is a bench bat used for damage; the bat has a clear source of damage.
56.0 Risk Priced
23
Rainiel Rodriguez STL · C · AA · 19y The current-performance ceiling scenario is a low-end everyday regular who contributes across categories, with a useful bench-bat floor; he is contributing a...
55.9 Still In The Buy Window
24
Cooper Flemming TBR · SS · A · 19y The sample covers 386 PA in Single-A, so confidence is low.
55.3 Young Runway
25
Kevin Alvarez HOU · CF · A · 18y He is 18 in Single-A over 330 PA, so confidence is low.
55.2 Young Runway
26
Tate Southisene ATL · SS · AA · 19y The line does not show a second offensive strength at the same level.
55.1 Still In The Buy Window
27
Theo Gillen TBR · CF · AA · 20y The current-performance ceiling scenario is an everyday run-producing bat, with on-base value protecting the floor; the power and patience reinforce each other.
55.0 Still In The Buy Window
28
Felnin Celesten SEA · SS · AA · 20y He is 20 in Double-A and High-A over 397 PA, so confidence is moderate.
54.9 Still In The Buy Window
29
Hayden Alvarez LAA · CF · A · 19y The sample covers 427 PA in Single-A, so confidence is low.
54.6 Young Runway
30
Jesús Made MIL · SS · AA · 19y He consistently finishes at-bats with contact; the open question is damage.
54.6 Young Runway
31
Taitn Gray TBR · 1B · A · 18y The line does not show a second offensive strength at the same level.
54.6 Young Runway
32
Caleb Bonemer CHW · 3B · AA · 20y He is 20 in Double-A and High-A over 411 PA, so confidence is moderate; the power is the reason to stay on him.
54.3 Still In The Buy Window
33
Charles Davalan LAD · CF · A+ · 22y The open question is damage.
53.9 Still In The Buy Window
34
Jefferson Rojas CHC · 3B · AA · 21y He barely strikes out; the open question is damage against better pitching.
53.6 Still In The Buy Window
35
Anthony Eyanson BOS · P · AA · 21y The strike throwing is adequate now; upper-level translation is the remaining test.
53.6 Still In The Buy Window
36
Yolfran Castillo TEX · SS · A+ · 19y He consistently finishes at-bats with contact; pitchers have little reason to avoid the zone.
53.6 Young Runway
37
Tyler Bremner LAA · P · A+ · 22y The sample covers 43.3 IP in High-A, so confidence is low.
53.5 Model Conviction
38
Xavier Neyens HOU · 3B · A+ · 19y There is enough power to keep pitchers honest; the miss rate keeps that power from showing up consistently.
53.5 Young Runway
39
Robert Arias CLE · CF · A · 19y He consistently finishes at-bats with contact; the open question is damage against better pitching.
53.4 Young Runway
40
Jonathan Santucci NYM · P · AA · 23y Rotation lean; the strike throwing decides whether it holds; he has a dependable way to finish hitters.
53.4 Still In The Buy Window
