Miceli began playing baseball during his senior year at Dr. Phillips High School in Florida[1] where he was teammates with Brian Barber and won a single game as a pitcher.

[3] The Pirates tried Miceli as both a starter and in the bullpen, but the right-hander found his niche as a reliever, collecting a career high 21 saves in 1995.

Miceli made stops in Florida, Texas, Cleveland, New York, Colorado (three times), Houston and even an overseas stay in Japan as member of the Yomiuri Giants.

Part of a closer by committee system in Tampa, Miceli earned four saves and held opponents to a .217 batting average.

Poor results during spring training cost the well traveled reliever a spot on Tampa Bay's forty-man roster, and on March 29, Miceli was released from the team.

On January 22, 2008, Miceli signed with the Boston Red Sox on a minor league contract with invitation to spring training.
