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.
CE inputs: Current contract information is unavailable. CE uses a neutral 100* fallback.
Neutral fallback: 0* NTV and 100* CE keep this player available in simulations while required inputs are reviewed.
* 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*.
2026 win contribution
1.15 Player Wins · 1.89 expected from replacement · -0.73 wins above replacement
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 77, Stick of 79, and Carry of 81, Jonah Heim sits in the 9th percentile, 9th percentile, and 9th percentile in those areas. His 60 Edge lands in the 8th percentile and ranks 103rd among catchers.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Jonah Heim's 79 Stick suggests he is performing close to the level supported by his underlying profile. It also places him in the 9th percentile and ranks 114th among catchers.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Jonah Heim's contributions to every team he played for. His 77 Perf is well below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 9th percentile and ranks 102nd among catchers.
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 -1.9, pitching +0.0, defense +0.3. The strongest rated teammates are Nick Kurtz at 130, Shea Langeliers at 125, and Zack Gelof at 124. Jonah Heim has contributed about as much as his own Perf suggests, resulting in a Carry of 81.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 31, Jonah Heim carries a 101 LI, which points to a steady near-term outlook without a major longevity advantage. That places him in the 16th percentile and ranks 786th among catchers.
CE Profile
100* CE is a neutral placeholder because a usable contract-value estimate cannot yet be calculated. It keeps Jonah Heim available in simulations and does not establish fair contract value.
NTV Profile
0* NTV is a neutral placeholder, not a finding that Jonah Heim has no value. Required inputs are incomplete; the player remains selectable in every simulation.
