Campusano grew up in the Santo Domingo suburb of Manoguayabo, along with Ramón Martínez and Juan Guzmán; together, they paved the pathway for MLB Hall of Famer Pedro Martínez to play for the Dominican Professional Baseball League (LIDOM) Tigres del Licey.

[1] Campusano was signed by the Dominican scout Epy Guerrero, as an international free agent, for the Toronto Blue Jays, in 1983.

Campusano was relegated to playing the entire 1989 season for the Blue Jays’ Triple-A Minor League Baseball (MiLB) affiliate in Syracuse.

His entire 1990 season was spent with the Philadelphia MLB squad, where he posted 18 H, in 85 AB, 66 G, with 2 HR (again), and 9 RBI.

For Phillies fans, Campusano is perhaps best remembered as a light-hitting reserve player, who broke up Pittsburgh Pirate Doug Drabek's no-hitter, on August 3, 1990.
