About these ratings
Tool ratings combine recorded performance with statistical estimates. Speed, arm, and fielding include outcome-based estimates rather than direct physical measurements.
Limited MLB evidence is weighted toward a neutral prior; no supported minor-league estimate is available.
CE estimate: Annual club costs do not reconcile with the reported obligation.
* 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 108, Stick of 133, and Carry of 117, Aroldis Chapman sits in the 87th percentile, 96th percentile, and 90th percentile in those areas. His 133 Edge lands in the 92nd percentile and ranks 19th among relief pitchers.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Aroldis Chapman's 133 Stick suggests he is performing far below what his underlying profile supports. It also places him in the 96th percentile and ranks 22nd among relief pitchers.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Aroldis Chapman's contributions to every team he played for. His 108 Perf is above average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 87th percentile and ranks 29th 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 +7.5, defense +0.1. The strongest rated teammates are Wilyer Abreu at 140, Willson Contreras at 131, and Payton Tolle at 118. Aroldis Chapman has carried more of the load than his individual results alone show, lifting his Carry to 117.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 38, Aroldis Chapman carries a 88 LI, which points to a shorter or less certain window due to role, age, or pitching risk. That places him in the 1st percentile and ranks 3430th among relief pitchers.
CE Profile
CE compares expected production with the money and years attached to a contract. The model uses a one season control horizon, $13.3 million average annual value, and about $13 million in contract-scenario costs for Aroldis Chapman. Options and arbitration can make those years or costs conditional; manual contract inputs may lag new agreements. His 141 CE shows that the club is receiving far more value than the contract costs, placing him in the 99th percentile and 18th among relief pitchers.
NTV Profile
NTV estimates Aroldis Chapman's value on a neutral trade market before the needs of a specific club are considered. His +16* NTV reflects his present ability, expected future value, age, contract, control, positional demand, and risk. That mark sits in the 84th percentile and ranks 118th among relief pitchers. Aroldis Chapman carries clear positive value and should return a useful major league piece or prospect package.
