Career Stats + Projections
Real MLB stats plus park-adjusted projections — this season (so far / rest / full), then future seasons and career totals.
basis chips:
RAW = as recorded ·
CTX = with park/league context ·
A+C = actual + context combined ·
MLE = level/park-neutral
Methodology▸ how WAR & MLE are computed
Stats are park-neutral MLB equivalents. The "TEAM" column shows current org affiliation only — we do NOT project at that team's park.
Rates (K%, BB%, HR-BF) are park-stripped; MiLB stat lines are translated to their MLB-equivalent via per-level MLE factors.
WAR is computed from projected runs prevented vs a replacement pitcher (the marginal arm a team would call up if this pitcher were unavailable) — calibrated to industry-standard fWAR.
