The 1998 Big 12 Championship Game was played on December 5, 1998, at the Trans World Dome in St. Louis, Missouri, United States.
Running back Sirr Parker scored 14 points on a pair of touchdown catches and a two-point conversion, rallying the Aggies to a 24-point surge in the final 9:20 of regulation and the extra periods.
Parker's unlikely 32-yard reception for the winning TD on a 3rd-and-17 situation for Texas A&M in the final overtime capped an evening of surprising developments for both teams.
The final six-pointer also gave the Aggies their first football win in history over a team ranked first nationally at the time of the contest.
Texas A&M had trouble finding the end zone in the first half against the Wildcats’ defense, as KSU built a 17–6 halftime advantage.
Quarterback Branndon Stewart reeled off 245 passing yards on 11-of-20 aerial work and two touchdowns in the final quarter and two overtime periods, as the Aggies mounted the greatest comeback in the brief history of the Big 12 Championship.
Texas A&M then converted as Parker caught the pass from Stewart and eluded one tackler before lunging over the pylon in the right corner for the winning score.
