Billy Beane

Billy Beane

Born Mar 29, 1962 · Orlando, FL · age 64

Turned the bottom-budget Oakland A's into a perennial contender through the value-hunting, data-driven philosophy immortalized in Michael Lewis's Moneyball — reshaping how the entire industry evaluates talent, even without a title in Oakland.

25 seasons with salary-era data across 1 stint. All figures are franchise-level outcomes during the tenure, not solely attributable to one executive.

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.
