Regular season and postseason are separate tables and are never summed into one career line; spring training is excluded entirely. Hitting and pitching come from different source rows, so a two-way player has both tables and neither borrows from the other. Innings pitched is summed as outs and converted once: the stored value counts thirds, so “6.1” means six innings and one out, and adding those as decimals understates a career. ERA and WHIP are computed from those totals rather than averaged across seasons. On-base percentage is (H + BB) over (AB + BB), which runs slightly under the official figure because the source rows carry no hit-by-pitch or sacrifice fly. The charts cover 2015 onward only, and the spray chart plots batted balls with a recorded landing spot: a strikeout or a walk has no location and is not a missing dot. Its field is a representative park, not the one the ball was hit in, because a spray chart pooled across a season is hit in thirty different outfields.
