Data notes

Last updated: 2026-05-03

MLB quiz data is built for quiz play from public baseball records. Career totals, season highs, player profile fields, handedness, and team labels may be normalized for consistent comparisons.

Missing profile fields are displayed as hidden or unavailable rather than being guessed. The MLB MVP data currently targets the same quiz granularity as the NPB core.
