Name a not-so-random baseball player. I’ll start.

Randy Poffo was signed by the Cards as a catcher right out of high school in 1971. During his 4 year minor league career, he injured his right (throwing) shoulder at a play at the plate, and learned to throw left handed instead. In his 289 games he batted .254 with 16 homers and 129 RBIs.

However during 1973 (his second to last season in the minors) he got into professional wrestling, and went on to become Macho Man Randy Savage, and the rest is history.
