Here’s about as “not really” missing in action as you can get, a 1970 card for former Philadelphia Phillies player Leroy Reams:
The sum total of Reams’ Major League career is one game, one plate appearance, one at-bat, which resulted in a strikeout.
The one taste of MLB action came on May 7th of the 1969 season, exactly TWO days before yours truly was born at Coney Island Hospital in Brooklyn, NY.
For Reams, after toiling in the Minor Leagues since 1962 for the
Phillies and New York Yankee organizations, he finally made it up on
that Spring day, pinch-hitting for pitcher Barry Lersch in a 6-1 loss
against the Houston Astros.
But he’d never see MLB action again, finishing up his pro career in the
Detroit Tigers organization in 1970 after batting a combined .193 over
46 games between Toledo and Montgomery.
