Campbell graduated from the University of Hawaii at Mānoa and made his major league debut in 1987 after being selected as the Mariners’ No. 1 draft pick.

A series of injuries, particularly to his right throwing shoulder, limited Campbell to just 17 major league appearances over the next ten years. He played for the Chicago White Sox, Milwaukee Brewers, Texas Rangers, San Diego Padres, Chicago Cubs, and Boston Red Sox organizations.
In 1996, his final MLB season, Campbell played 13 games for the Cubs, finishing with a 3-1 record and a 4.46 ERA. Over six MLB seasons, he had a 12-19 record and a 5.86 ERA in 51 games (41 starts). In 1997, he spent one season with the Yokohama Bay Stars in Japan.
According to Newsweek, Campbell and former Mariners batboy Steve Towey partnered after retirement to create Shiskaberry’s, a dessert franchise with concession booths at multiple professional sports venues.
