James David Adduci (born August 9, 1959) is an American former professional baseball outfielder and first baseman.

Since he had three sacrifice flies, his on-base percentage was lower than his batting average, which is a very rare occurrence in Major League Baseball.

[1] After retirement following a 1990 season spent in the minor leagues, the Chicago native Adduci entered DePaul University, and in 1991 he earned a communications media degree.

Fellow ex-professionals Steve Otto and Tim Pyznarski were on staff helping Adduci as instructors.

During his playing career, he befriended players like Paul Molitor and Andy Van Slyke, who named Adduci the godfather of his son.

[3] Currently, Adduci works for the Chicago Bulls/Sox Training Academy as the director of the White Sox Elite baseball program and as a hitting instructor.
