Jacob Wilson Extension: WAR Projections Show Athletics Building Elite Infield Core
The Athletics officially signed All-Star shortstop Jacob Wilson to a 7-year, $70 million extension Monday, and the advanced metrics tell a compelling story. Wilson's 2025 rookie campaign produced 3.0 fWAR, a .311/.355/.444 slash line (121 OPS+), and elite contact skills that ranked third in AL batting average. At just 23 years old (drafted 6th overall in 2023 out of Grand Canyon), his age-adjusted WAR trajectory projects to 3.5-4.5 fWAR annually through his prime years. The contract structure is analytically sound: $10M AAV through 2032 with a club option for 2033 avoids arbitration for 2027-2029 and locks in pre-free-agency production. ZiPS projections show Wilson's expected wOBA (.355) and xBA (.298) both ranking among top-10 AL shortstops. The Athletics' infield now projects for combined 9.2-11.5 fWAR with Wilson, Soderstrom (2.8-3.2 projected), Butler (1.8-2.2), and Rooker (2.6-3.0). For futures bettors tracking WAR-based win models: Oakland's team projection should rise from 71.3 to 73.8 wins, pushing their market line of 69.5 into clear over territory. The franchise's youth movement, averaging just 24.6 years for their extended core, represents the AL's most sustainable foundation heading into their 2028 Las Vegas relocation.
