Tulsa and ORU had their first meeting on March 4, 1974, which Tulsa won 85–84. The series has been hard fought since then, and Tulsa holds the edge in the overall series 34–19. The rivalry has been marked by remarkable runs either way: Oral Roberts won 8 consecutive match-ups in the late 1970s; directly following that streak, Tulsa won the next 13 in a row and 24 of 27 between December 8, 1980 and December 19, 2002. The rivalry has become more balanced in recent years, with each school winning 8 games over the past 16 meetings. The largest margin of victory was 45 points, by Tulsa over ORU in 1994. Another turning point in the rivalry was Tulsa's hiring of Bill Self away from Oral Roberts prior to the 1997–98 season.
The ORU and TU Women's basketball teams have faced off in the series since 1976. The ORU Women's team has dominated, 30–7, including a 20-game streak from 1976 through 1999.
