He spent five years in the major leagues with the Arizona Diamondbacks, Tampa Bay Devil Rays, Milwaukee Brewers, and Texas Rangers.

Prior to the start of the 2003 season, Conti was traded to the Milwaukee Brewers for catcher Javier Valentín.

Conti gained slight fame during his major league career by showing off an excellent defensive throwing arm from the outfield.

Conti, as a member of the Arizona Diamondbacks, on consecutive nights threw out Atlanta's Brian Jordan at third base with throws from deep in right field.

A few seasons later as a member of the Tampa Bay Devil Rays, Conti gunned down Chicago's Frank Thomas at home plate on consecutive nights.
