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: 90.8% MLB and 9.2% level-adjusted minor-league estimate.
Minor-league valuation uses season-decayed historical statistics because the current-season sample is limited.
Minor-league estimate: 2.6% observed statistical weight and 97.4% 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*.

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 111, Stick of 140, and Carry of 118, Garrett Whitlock sits in the 89th percentile, 98th percentile, and 90th percentile in those areas. His 140 Edge lands in the 93rd percentile and ranks 12th among relief pitchers.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Garrett Whitlock's 140 Stick suggests he is performing far below what his underlying profile supports. It also places him in the 98th percentile and ranks 13th among relief pitchers.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Garrett Whitlock's contributions to every team he played for. His 111 Perf is above average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 89th percentile and ranks 20th 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 +5.8, defense +0.0. The strongest rated teammates are Wilyer Abreu at 140, Willson Contreras at 131, and Payton Tolle at 118. Garrett Whitlock has contributed about as much as his own Perf suggests, resulting in a Carry of 118.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 30, Garrett Whitlock carries a 97 LI, which points to a steady near-term outlook without a major longevity advantage. That places him in the 3rd percentile and ranks 3197th 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, $4.7 million average annual value, and about $7.5 million in contract-scenario costs for Garrett Whitlock. 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 20th among relief pitchers.
NTV Profile
NTV estimates Garrett Whitlock's value on a neutral trade market before the needs of a specific club are considered. His +23* NTV reflects his present ability, expected future value, age, contract, control, positional demand, and risk. That mark sits in the 93rd percentile and ranks 14th among relief pitchers. Garrett Whitlock carries clear positive value and should return a useful major league piece or prospect package.
