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: 18.8% MLB and 81.3% level-adjusted minor-league estimate.
Minor-league estimate: 49.1% observed statistical weight and 50.9% historical peer baseline; individual tools use their own sample weights.

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 86, Stick of 90, and Carry of 90, Seth Martinez sits in the 45th percentile, 31st percentile, and 44th percentile in those areas. His 74 Edge lands in the 31st percentile and ranks 350th among relief pitchers.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Seth Martinez's 90 Stick suggests he is performing close to the level supported by his underlying profile. It also places him in the 31st percentile and ranks 509th among relief pitchers.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Seth Martinez's contributions to every team he played for. His 86 Perf is below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 45th percentile and ranks 293rd 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 -0.2, defense +0.0. The strongest rated teammates are Wilyer Abreu at 140, Willson Contreras at 131, and Payton Tolle at 118. Seth Martinez has contributed about as much as his own Perf suggests, resulting in a Carry of 90.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 32, Seth Martinez 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 3308th 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, $0.8 million average annual value, and about $0.8 million in contract-scenario costs for Seth Martinez. 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 3351st among relief pitchers.
NTV Profile
NTV estimates Seth Martinez's value on a neutral trade market before the needs of a specific club are considered. His +6* NTV reflects his present ability, expected future value, age, contract, control, positional demand, and risk. That mark sits in the 48th percentile and ranks 1473rd among relief pitchers. Seth Martinez has modest positive value, though the market return would depend heavily on fit and demand.
