Camacho spent 1958 through 1968 out of professional baseball, working as a teacher and high school baseball coach and as a senior instructor with the Ted Williams Baseball Camp in Lakeville, Massachusetts. When Williams was named manager of the Washington Senators during the 1968–69 offseason, he called former Boston Red Sox teammate Johnny Pesky and invited Pesky to be his bench coach. But Pesky had just taken a job with the Red Sox' radio and television broadcast team and decided to honor his contract and remain in Boston. Williams then made Camacho his dugout aide.
