Filed by surname, ignoring a trailing Jr., Sr. or numeral: Derrick Jones Jr. is under J for Jones. A player with a single name files under its first letter rather than disappearing. Hitting and pitching are separate rows in the source and are merged here on player id, so a dash means no line of that kind rather than a zero the player earned. Innings are summed as outs and converted once, because “6.1” is six innings and one out. Every figure is 2025 regular season; spring training and the postseason are excluded.
