These ratings blend a limited performance sample with a historical peer baseline and remain provisional.
About these ratings
Tool ratings combine recorded performance with statistical estimates. Speed, arm, and fielding include outcome-based estimates rather than direct physical measurements.
Some tools are unavailable. MD means missing data; unavailable tools are left out of the graph, not scored as zero.
Limited MLB evidence: 2.5% MLB and 97.5% level-adjusted minor-league estimate.
Minor-league estimate: 42.6% observed statistical weight and 57.4% historical peer baseline; individual tools use their own sample weights.
* On NTV, this indicates estimated or unverified inputs. CE uses an asterisk only when current contract information is unavailable.
CE uses the best available contract information, including partial terms, estimated salaries, and projected team control. CE shows an asterisk only when current contract information is unavailable; free agents without a current agreement use 100*.

Includes contributions to every team played for in 2026. Perf expresses wins above replacement on a scale where 100 is average. How the win totals reconcile
Six-tool graphs show percentiles from available performance evidence. Speed uses baserunning outcomes; Arm uses position-adjusted throwing outcomes. Movement describes tracked pitch movement within pitch type. Minor-league comparisons account for competition level; unavailable measurements display MD.
Edge Profile
Edge combines Perf, Stick, and Carry to show how valuable a player is right now. With a Perf of 87, Stick of 100, and Carry of 91, Welinton Herrera sits in the 50th percentile, 65th percentile, and 50th percentile in those areas. His 82 Edge lands in the 50th percentile and ranks 241st among relief pitchers.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Welinton Herrera's 100 Stick suggests he is performing below what his underlying profile supports. It also places him in the 65th percentile and ranks 288th among relief pitchers.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Welinton Herrera's contributions to every team he played for. His 87 Perf is below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 50th percentile and ranks 263rd among relief pitchers.
Carry Profile
Carry places Perf in the context of the roster around a player and includes a bounded clutch adjustment for offense, pitching, and defense when available. Close games and later innings earn more weight, and difficult defensive plays receive their own credit. His clutch runs are offense +0.0, pitching +0.0, defense +0.0. The strongest rated teammates are TJ Rumfield at 136, Hunter Goodman at 125, and Kyle Karros at 114. Welinton Herrera has contributed about as much as his own Perf suggests, resulting in a Carry of 91.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 22, Welinton Herrera carries a 102 LI, which points to a steady near-term outlook without a major longevity advantage. That places him in the 28th percentile and ranks 1990th among relief pitchers.
CE Profile
CE compares expected production with the money and years attached to a contract. The model uses a 6 seasons control horizon, $0.1 million average annual value, and about $0.1 million in contract-scenario costs for Welinton Herrera. Options and arbitration can make those years or costs conditional; manual contract inputs may lag new agreements. His 100 CE is close to a fair exchange between salary and production, placing him in the 11th percentile and 3408th among relief pitchers.
NTV Profile
NTV estimates Welinton Herrera's value on a neutral trade market before the needs of a specific club are considered. His +22* NTV reflects his present ability, expected future value, age, contract, control, positional demand, and risk. That mark sits in the 92nd percentile and ranks 20th among relief pitchers. Welinton Herrera carries clear positive value and should return a useful major league piece or prospect package.
