While making a living as a factory worker, DiOrio devoted his spare time to his passion, playing soccer. In 1942, he was on the roster of
Morgan Strasser when it lost the
National Amateur Cup to Fall River. However, the team took the cup in 1943 with a victory over Santa Maria S.C. In 1944, Morgan Strasser went to a third straight Amateur Cup final, but lost to
S.C. Eintracht. In 1946, DiOrio left Morgan Strasser, for the
Pittsburgh Strasser of the newly established
North American Soccer Football League. In 1947 he moved to the
Chicago Vikings. After the collapse of the NAFSL, following the 1947 season, DiOrio signed with the
Pittsburgh Indians in September. In 1949, the club won the
National Challenge Cup. In 1950, he was with Pittsburgh Harmarville when they lost the National Amateur Cup final to
Ponta Delgada S.C. In 1951, DiOrio lost another Amateur Cup final, his fourth. However, Harmarville followed those two losses with a National Challenge Cup championship in 1952. At some point, he left Harmarville and signed with
Pittsburgh Beadling, with whom he finished his career in 1959. During his twenty years of playing soccer, DiOrio won the National Amateur Cup, National Challenge Cup, and five Keystone Senior League championships. ==National team==
