Youngest ever

MLB Age Milestones

The youngest players in MLB history to reach 4 milestones: 1,000 career hits, 100 career home runs, 100 career pitching wins, 1,000 career strikeouts (pitching). Violet badge = age 20 or younger.

Rankings as of 2026-10-03, as declared by the corpus that produced them.

How this is computed

For each milestone, the first regular season in which a player reached it — a running career total or a single season — and the player's age that season. Ranked youngest first by exact age at the reference date; ties in whole years are broken by days. Age as of June 30 of the season (the baseball-reference convention). 22,706 of 23,620 profiles carry a full birth date.

Counting stats are summed from the regular-season rows in each player profile; a traded season uses its combined row, never the team rows twice.
A career milestone is placed in the season the running total crossed the line; the exact game is not in the corpus.
Players without a full birth date in the corpus cannot be aged and are counted, not ranked.
Rows cover the major leagues in the corpus from 1876, including the recognized Negro Leagues seasons it carries.
