About these ratings
Tool ratings combine recorded performance with statistical estimates. Speed, arm, and fielding include outcome-based estimates rather than direct physical measurements.
Current club control is unverified. Any usable estimate uses the last available contract inputs and does not establish current trade rights.
Limited MLB evidence: 12.0% MLB and 88.0% level-adjusted minor-league estimate.
Minor-league estimate: 68.9% observed statistical weight and 31.1% 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*.

Includes contributions to every team played for in 2026. Perf expresses wins above replacement on a scale where 100 is average. How the win totals reconcile
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 84, Stick of 98, and Carry of 87, Junior Perez sits in the 32nd percentile, 57th percentile, and 27th percentile in those areas. His 83 Edge lands in the 52nd percentile and ranks 59th among left fielders.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Junior Perez's 98 Stick suggests he is performing below what his underlying profile supports. It also places him in the 57th percentile and ranks 65th among left fielders.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Junior Perez's contributions to every team he played for. His 84 Perf is below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 32nd percentile and ranks 72nd 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 -1.6, pitching +0.0, defense -0.4. The strongest rated teammates are Miguel Vargas at 148, Tristan Peters at 130, and Chase Meidroth at 129. Junior Perez has contributed about as much as his own Perf suggests, resulting in a Carry of 87.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 25, Junior Perez carries a 106 LI, which points to a steady near-term outlook without a major longevity advantage. That places him in the 52nd percentile and ranks 131st among left fielders.
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 Junior Perez. Options and arbitration can make those years or costs conditional; manual contract inputs may lag new agreements. His 102 CE is close to a fair exchange between salary and production, placing him in the 29th percentile and 62nd among left fielders.
NTV Profile
NTV estimates Junior Perez's value on a neutral trade market before the needs of a specific club are considered. His +22* NTV reflects his present ability, expected future value, age, contract, control, positional demand, and risk. That mark sits in the 92nd percentile and ranks 36th among left fielders. Junior Perez carries clear positive value and should return a useful major league piece or prospect package.
