The physically imposing 6'5" Connors played first base for the Cubs in 1951 and hit a whopping two home runs in 200 at bats, not exactly the kind of power you want from a big first baseman. That performance earned him a trip back to the minors.
Luckily for him, the Cubs minor league team at the time was in Los Angeles. While he was playing in the Cubs minor league system he got a bit part in the movie Pat & Mike (starring Spencer Tracy--1952). That led him to quit baseball for good and become a full-time actor. By 1958, he was starring in The Rifleman, which aired until 1963. He also starred in Old Yeller, Soylent Green, and Roots, and is arguably the greatest Cubs actor of all-time (other than Sammy Sosa during his "corked bat" press conference).
He was born on this day in 1921.
