About these ratings
Tool ratings combine recorded performance with statistical estimates. Speed, arm, and fielding include outcome-based estimates rather than direct physical measurements.
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
5.11 Player Wins · 2.11 expected from replacement · 3.00 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 124, Stick of 88, and Carry of 138, Zack Gelof sits in the 95th percentile, 26th percentile, and 96th percentile in those areas. His 130 Edge lands in the 91st percentile and ranks 7th among second basemen.
Stick Profile
Stick looks beyond the immediate results and estimates what should hold over a larger sample. Zack Gelof's 88 Stick suggests he is vastly outperforming what his underlying profile supports. It also places him in the 26th percentile and ranks 57th among second basemen.
Perf Profile
Perf measures season wins above replacement after allocating each team's actual wins to its players. It includes Zack Gelof's contributions to every team he played for. His 124 Perf is excellent on a scale where 100 is average and 20 points is one standard deviation. It sits in the 95th percentile and ranks 7th among second 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 +1.8, pitching +0.0, defense +1.5. The strongest rated teammates are Nick Kurtz at 130, Shea Langeliers at 125, and Henry Bolte at 110. Zack Gelof has carried more of the load than his individual results alone show, lifting his Carry to 138.
LI Profile
LI looks at how much useful baseball a player may still have ahead of him. At age 27, Zack Gelof carries a 107 LI, which points to a steady near-term outlook without a major longevity advantage. That places him in the 65th percentile and ranks 278th among second basemen.
CE Profile
CE compares expected production with the money and years attached to a contract. The model uses a 4 seasons control horizon, $0.3 million average annual value, and about $0.3 million in contract-scenario costs for Zack Gelof. Options and arbitration can make those years or costs conditional; manual contract inputs may lag new agreements. His 131 CE shows that the club is receiving far more value than the contract costs, placing him in the 97th percentile and 10th among second basemen.
NTV Profile
NTV estimates Zack Gelof's value on a neutral trade market before the needs of a specific club are considered. His +27 NTV reflects his present ability, expected future value, age, contract, control, positional demand, and risk. That mark sits in the 95th percentile and ranks 22nd among second basemen. Zack Gelof carries clear positive value and should return a useful major league piece or prospect package.
