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: 40.4% observed statistical weight and 59.6% 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
0.07 Player Wins · 0.09 expected from replacement · -0.03 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 86, Stick of 95, and Carry of 90, John Brebbia sits in the 45th percentile, 46th percentile, and 44th percentile in those areas. His 77 Edge lands in the 38th percentile and ranks 300th among relief pitchers.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. John Brebbia's 95 Stick suggests he is performing below what his underlying profile supports. It also places him in the 46th percentile and ranks 401st among relief pitchers.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes John Brebbia's contributions to every team he played for. His 86 Perf is below average on a scale where 100 is average and 20 points is one standard deviation. It sits in the 45th percentile and ranks 284th among relief pitchers.
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 +0.0, pitching +0.0, defense +0.0. The strongest rated teammates are Wilyer Abreu at 140, Willson Contreras at 131, and Payton Tolle at 118. John Brebbia has contributed about as much as his own Perf suggests, resulting in a Carry of 90.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 36, John Brebbia carries a 88 LI, which points to a shorter or less certain window due to role, age, or pitching risk. That places him in the 1st percentile and ranks 3447th among relief pitchers.
CE Profile
100* CE is a neutral placeholder because a usable contract-value estimate cannot yet be calculated. It keeps John Brebbia available in simulations and does not establish fair contract value.
NTV Profile
0* NTV is a neutral placeholder, not a finding that John Brebbia has no value. Required inputs are incomplete; the player remains selectable in every simulation.
