The first wrestling duel in the newly renamed Gallagher Hall was held on January 27, 1939, against Indiana with A&M winning 18–6. The distinction of being the first A&M (Oklahoma State) wrestler to compete in Gallagher Hall goes to three-time NCAA champion Joe McDaniel of Sulphur, OK. McDaniel defeated Donnacher of Indiana, 13–2. On February 3, 1989, the Oklahoma State Cowboys hosted the Hoosiers in a celebration of the 50-year anniversary of the first Gallagher Hall dual. The Cowboys defeated the Hoosiers, 28–6. Former wrestling coach Myron Roderick claimed that during the 1978 Big 8 Conference Finals, over 9,000 fans packed the old barn and saw unranked Daryl Monasmith beat the
