Born on October 7, 1964, in Reading, Pennsylvania, DeLucia honed his skills at the University of Tennessee before making his professional debut. His journey through the minor leagues culminated in his MLB debut with the Mariners on September 8, 1990.

DeLucia's rookie season in 1991 saw him take on a starting role for the Mariners. He appeared in 30 games, starting 27 of them, and posted a 12-13 record with a 4.51 ERA.

During his time with the Mariners, DeLucia demonstrated his ability to handle the pressures of starting in the major leagues.

In 1993, DeLucia was traded to the Cincinnati Reds, where he transitioned from a starting pitcher to a reliever. This shift in role allowed him to adapt and find a new niche within the bullpen. Over the next few seasons, DeLucia played for several teams, including the San Francisco Giants, Anaheim Angels, and St. Louis Cardinals.

In 1999, DeLucia signed with the Cleveland Indians, marking the final chapter of his MLB career.
