Frank Kostro (#44)

It looks like Frank Kostro played minor-league baseball forever. So much so that there's no room on the back of his card for any commentary.

Kostro's card displays the dreaded position of "INF-OF". In reality, he was primarily a pinch hitter in 1967 and 1968, while playing only 4 games in the field in 1967, and in a few dozen games in 1968. He ended his career in 1969 with 2 pinch-hitting appearances for the Twins.
