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: 39.3% MLB and 60.7% level-adjusted minor-league estimate.
Minor-league estimate: 60.0% observed statistical weight and 40.0% 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 80, Stick of 88, and Carry of 84, Will Brennan sits in the 16th percentile, 26th percentile, and 16th percentile in those areas. His 68 Edge lands in the 18th percentile and ranks 102nd among left fielders.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Will Brennan's 88 Stick suggests he is performing below what his underlying profile supports. It also places him in the 26th percentile and ranks 108th among left fielders.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Will Brennan's contributions to every team he played for. His 80 Perf is below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 16th percentile and ranks 99th among left fielders.
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 -0.9, pitching +0.0, defense -0.2. The strongest rated teammates are Rafael Devers at 116, Bryce Eldridge at 113, and Landen Roupp at 113. Will Brennan has contributed about as much as his own Perf suggests, resulting in a Carry of 84.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 28, Will Brennan carries a 109 LI, which points to a steady near-term outlook without a major longevity advantage. That places him in the 79th percentile and ranks 104th among left fielders.
CE Profile
CE compares expected production with the money and years attached to a contract. The model uses a 3 seasons control horizon, $0.9 million average annual value, and about $0.4 million in contract-scenario costs for Will Brennan. 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 146th among left fielders.
NTV Profile
NTV estimates Will Brennan's value on a neutral trade market before the needs of a specific club are considered. His +10* NTV reflects his present ability, expected future value, age, contract, control, positional demand, and risk. That mark sits in the 68th percentile and ranks 83rd among left fielders. Will Brennan carries clear positive value and should return a useful major league piece or prospect package.
