Gabe Kapler
★ activeBorn Jul 31, 1975 · Hollywood, CA · age 51
Reached the front office after a long playing career and managing the Phillies and Giants, where his 107-win 2021 club earned him NL Manager of the Year — a progressive, analytics-forward voice now working in baseball operations.
Across the full 1-season sample, the measured profile stands out most for cheap-talent surplus (100th percentile), avoidance of negative WAR (95th percentile), and payroll-adjusted roster quality (77th percentile). The clearest contrast is drafted-player surplus (2nd percentile): drafted players have created less surplus value than for most peers. Because the sample covers fewer than five seasons, those comparisons are descriptive rather than stable.
1 seasons with salary-era data across 1 stint. All figures are franchise-level outcomes during the tenure, not solely attributable to one executive.

Trade-side columns: RFA is playoff-readiness percentage points added to the future roster foundation. It grades the franchise's entire side of a trade, so the same score repeats for every player acquired in that package. PPA/CPA remain player-level arrival-year probability points.
WAB = wins above what the team's payroll predicted (resource-controlled). WAR surplus = era-neutral value (WAR minus payroll in win-equivalents). Roster surplus $M = dollar value of WAR over cost. Build channels (realized fWAR): HG = home-grown via amateur draft / international signing; Trade = acquired minus surrendered (incl. purchases/waivers); FA = signed minus walked; R5 = Rule-5 / minor-league-draft pickups. Credit follows the acquisition year — home-grown to the regime at the player's draft/signing (not whoever was in the chair when he peaked), trade/FA/R5 to the GM who made the move. Players acquired as prospects before debuting (e.g. Smoltz, Bagwell; Rule-5 picks like Uggla) are counted as trade/R5, not home-grown. All are franchise-level outcomes during the stint, not solely attributable to one executive.
