Despite starting in May, Quarry had 14 matches in 1965 at the start of his pro career. Many of his early career fights took place at the Olympic Auditorium in Los Angeles, where he became established as a draw. Quarry supplemented meager boxing pay by working as a tire changer at a Greyhound bus terminal. Quarry was fast handed and an effective counter puncher, but with a tendency to neglect defense and rely on his excellent chin. He had three draws on his record by the time of his first loss, which came in his 21st bout in July 1966 against crafty spoiler Eddie Machen, known for his feat of breaking Sonny Liston's run of knockouts. More careful promotor's choice of opponents for their ticket selling asset subsequently saw Quarry rise in the rankings.
