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: 75.0% MLB and 25.0% level-adjusted minor-league estimate.
Minor-league estimate: 54.1% observed statistical weight and 45.9% historical peer baseline; individual tools use their own sample weights.

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 78, Stick of 74, and Carry of 83, Leo Rivas sits in the 11th percentile, 5th percentile, and 13th percentile in those areas. His 58 Edge lands in the 6th percentile and ranks 62nd among third basemen.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Leo Rivas' 74 Stick suggests he is performing close to the level supported by his underlying profile. It also places him in the 5th percentile and ranks 81st among third basemen.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Leo Rivas's contributions to every team he played for. His 78 Perf is well below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 11th percentile and ranks 56th among third 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 -0.3, pitching +0.0, defense +0.3. The strongest rated teammates are Randy Arozarena at 142, Bryan Woo at 130, and Cole Young at 109. Leo Rivas has contributed about as much as his own Perf suggests, resulting in a Carry of 83.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 29, Leo Rivas 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 270th among third basemen.
CE Profile
CE compares expected production with the money and years attached to a contract. The model uses a 5 seasons control horizon, $0.8 million average annual value, and about $0.8 million in contract-scenario costs for Leo Rivas. 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 267th among third basemen.
NTV Profile
NTV estimates Leo Rivas'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 142nd among third basemen. Leo Rivas carries clear positive value and should return a useful major league piece or prospect package.
