Dave was born in Seneca Falls, NY and he was both a starter and a reliever during an effective 15 year MLB career from 1962 to 1977. His father played semi-pro baseball around central New York State, but stopped playing when Dave was born. His uncle was John Pannucci, who played baseball and football at Syracuse University from 1954 to 1957 and was the backup quarterback during the Jim Brown era.

Dave helped win the world series for the Pirates in 1971. He appeared in three games in the Series, allowing no runs, and earning a save in Game Four (03:04:26). He was awarded The Sporting News Reliever of the Year Award in 1971. In 1973, Giusti was selected for the National League's All-Star Team.

The palmballer Giusti saved 20 or more games four years in a row. He ended his career with the Chicago Cubs in 1977. After retiring, Dave has served as the vice president of the Pirates Alumni Association.  Dave was a pioneer of the modern-day closer role and redefined that aspect of the game.

After his baseball career, Giusti became a corporate sales manager for American Express. As of 2002, he retired in Mt. Lebanon, Pennsylvania.
