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 contract and service-control terms are unavailable. Historical statistics remain available.
Minor-league estimate: 30.2% observed statistical weight and 69.8% historical peer baseline; individual tools use their own sample weights.
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
0.32 Player Wins · 0.70 expected from replacement · -0.38 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 81, Stick of 111, and Carry of 86, Jahmai Jones sits in the 19th percentile, 84th percentile, and 23rd percentile in those areas. His 87 Edge lands in the 60th percentile and ranks 42nd among left fielders.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Jahmai Jones' 111 Stick suggests he is performing far below what his underlying profile supports. It also places him in the 84th percentile and ranks 24th among left fielders.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Jahmai Jones's contributions to every team he played for. His 81 Perf is below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 19th percentile and ranks 91st 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 +0.7, pitching +0.0, defense -0.5. The strongest rated teammates are Wilyer Abreu at 140, Willson Contreras at 131, and Payton Tolle at 118. Jahmai Jones has contributed about as much as his own Perf suggests, resulting in a Carry of 86.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 29, Jahmai Jones 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 68th among left fielders.
CE Profile
100* CE is a neutral placeholder because a usable contract-value estimate cannot yet be calculated. It keeps Jahmai Jones available in simulations and does not establish fair contract value.
NTV Profile
0* NTV is a neutral placeholder, not a finding that Jahmai Jones has no value. Required inputs are incomplete; the player remains selectable in every simulation.
