Historically poor defense raises questions about Seattle’s development plan

Seattle’s 2026 fielding runs value was -59, fifth-worst among 300 full-season teams since 2016; one analysis estimates defense cost six to seven wins. Kwan’s elite outfield range is a potential defensive benefit in speculative roster-fit discussion, not evidence of a pursuit. Cole Young’s Gold Glove result remains pending, and Perry Hill’s departure sharpens questions about defensive development.
