He was selected by the Toronto Blue Jays from the Yankees organization in the 1976 Major League Baseball expansion draft.

He was a utility player who spent most of his career as the right-handed half of a third-base platoon with Rance Mulliniks called "Mullinorg".

Iorg was most recognizable for his strange batting stance, on the toes of his front foot and leaning back toward the catcher as the ball was being pitched.

Usually a singles hitter, Iorg had the highest batting average (.313) and a .469 slugging percentage on the Blue Jays in their division-winning 1985 season.

Iorg was hired by the Milwaukee Brewers as a roving instructor and served as a third base coach for the final 12 games of the 2008 season, after Dale Sveum became the interim manager.

[citation needed] He is honored in his home town of Blue Lake, California, which named its baseball field after him and his brothers.
