Youngest big leaguer

Cincinnati Reds broadcaster Joe Nuxhall has died. Long before he was a broadcaster Nuxhall set a major league record:

Nuxhall’s place in baseball lore was secured the moment he stepped onto a big-league field. With major league rosters depleted during World War II, he got a chance to pitch in relief for the Reds on June 10, 1944.

No one in modern baseball history has played in the majors at such a young age — 15 years, 10 months, 11 days old. He got two outs against St. Louis before losing his composure, then went eight years before pitching for the Reds again.
