Another turning point in the rivalry was TU's hiring of Bill Self away from ORU prior to the 1997–98 season.

The 2014 PSO Mayor's Cup Men's game, held on November 15 at Oral Roberts' Mabee Center, was won by ORU by a score of 77–68, serving as the second straight win in the series by the Golden Eagles.

The 2014 PSO Mayor's Cup Women's game, held on November 21, was also won by ORU by a score of 73–71.

Oral Roberts swept the PSO Mayor's Cup games again in 2015, this time at Tulsa's Reynolds Center, with the Golden Eagle women winning 59–53 on November 20, and the ORU men taking their third in a row in the series, 70–68 on December 5.

The series has seen three interruptions in its history: four seasons spanning 1987 to 1991 when Oral Roberts dropped to NAIA status; in 2010-11 when Tulsa would not agree to a date for the contracted game at ORU's Mabee Center, and 2020-21 when TU opted out of games at Arkansas and ORU due to COVID issues in the program.
