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: 69.8% MLB and 30.2% level-adjusted minor-league estimate.
Minor-league estimate: 58.0% observed statistical weight and 42.0% 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 87, Stick of 86, and Carry of 93, Anthony Seigler sits in the 50th percentile, 21st percentile, and 58th percentile in those areas. His 77 Edge lands in the 38th percentile and ranks 49th among second basemen.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Anthony Seigler's 86 Stick suggests he is performing close to the level supported by his underlying profile. It also places him in the 21st percentile and ranks 61st among second basemen.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Anthony Seigler's contributions to every team he played for. His 87 Perf is below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 50th percentile and ranks 43rd among second basemen.
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 +1.8, pitching +0.0, defense +0.4. The strongest rated teammates are Wilyer Abreu at 140, Willson Contreras at 131, and Payton Tolle at 118. Anthony Seigler has contributed about as much as his own Perf suggests, resulting in a Carry of 93.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 27, Anthony Seigler carries a 107 LI, which points to a steady near-term outlook without a major longevity advantage. That places him in the 65th percentile and ranks 195th among second basemen.
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 Anthony Seigler. 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 223rd among second basemen.
NTV Profile
NTV estimates Anthony Seigler's value on a neutral trade market before the needs of a specific club are considered. His +12* NTV reflects his present ability, expected future value, age, contract, control, positional demand, and risk. That mark sits in the 75th percentile and ranks 113th among second basemen. Anthony Seigler carries clear positive value and should return a useful major league piece or prospect package.
