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: 3.5% MLB and 96.5% level-adjusted minor-league estimate.
Minor-league estimate: 62.5% observed statistical weight and 37.5% 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 85, Stick of 102, and Carry of 89, Seth Lonsway sits in the 39th percentile, 71st percentile, and 38th percentile in those areas. His 81 Edge lands in the 47th percentile and ranks 254th among relief pitchers.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Seth Lonsway's 102 Stick suggests he is performing below what his underlying profile supports. It also places him in the 71st percentile and ranks 230th among relief pitchers.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Seth Lonsway's contributions to every team he played for. His 85 Perf is below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 39th percentile and ranks 330th 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 Rafael Devers at 116, Bryce Eldridge at 113, and Landen Roupp at 113. Seth Lonsway has contributed about as much as his own Perf suggests, resulting in a Carry of 89.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 28, Seth Lonsway carries a 99 LI, which points to a steady near-term outlook without a major longevity advantage. That places him in the 10th percentile and ranks 2983rd 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, $0.8 million average annual value, and about $0.8 million in contract-scenario costs for Seth Lonsway. Options and arbitration can make those years or costs conditional; manual contract inputs may lag new agreements. His 101 CE is close to a fair exchange between salary and production, placing him in the 23rd percentile and 2723rd among relief pitchers.
NTV Profile
NTV estimates Seth Lonsway's value on a neutral trade market before the needs of a specific club are considered. His +4* NTV reflects his present ability, expected future value, age, contract, control, positional demand, and risk. That mark sits in the 36th percentile and ranks 1926th among relief pitchers. Seth Lonsway has modest positive value, though the market return would depend heavily on fit and demand.
