About these ratings

Tool ratings combine recorded performance with statistical estimates. Speed, arm, and fielding include outcome-based estimates rather than direct physical measurements.

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*.

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 64, Stick of 72, and Carry of 68, Merrill Kelly sits in the 1st percentile, 3rd percentile, and 1st percentile in those areas. His 36 Edge lands in the 1st percentile and ranks 203rd among starting pitchers.

Stick Profile

Stick looks beyond the immediate results and estimates what should hold over a larger sample. Merrill Kelly's 72 Stick suggests he is performing below what his underlying profile supports. It also places him in the 3rd percentile and ranks 239th among starting pitchers.

Perf Profile

Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Merrill Kelly's contributions to every team he played for. His 64 Perf is well below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 1st percentile and ranks 203rd among starting 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 -3.0, defense +0.3. The strongest rated teammates are Gabriel Moreno at 163, Corbin Carroll at 156, and Geraldo Perdomo at 154. Merrill Kelly has contributed about as much as his own Perf suggests, resulting in a Carry of 68.

LI Profile

LI looks at how much useful baseball a player may still have ahead of him. At age 38, Merrill Kelly carries a 93 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 1696th among starting pitchers.

CE Profile

CE compares expected production with the money and years attached to a contract. The model uses a 2 seasons control horizon, $20 million average annual value, and about $40 million in contract-scenario costs for Merrill Kelly. Options and arbitration can make those years or costs conditional; manual contract inputs may lag new agreements. His 40 CE marks the contract as a substantial drag on his value, placing him in the 1st percentile and 1703rd among starting pitchers.

NTV Profile

NTV estimates Merrill Kelly's value on a neutral trade market before the needs of a specific club are considered. His -158 NTV reflects his present ability, expected future value, age, contract, control, positional demand, and risk. That mark sits in the 1st percentile and ranks 1703rd among starting pitchers. Merrill Kelly is deeply underwater as a trade asset and would likely require substantial salary relief or added value to move.
