They'll now play three games as part of a pool play format, starting off the week's festivities at Chickasaw Bricktown Ballpark with a 9 a.m. Thursday contest against No. 5 Baylor that was originally scheduled for a day earlier.
With the league changing from its previously expected double elimination format, everything was moved back a day, forcing each team to play a maximum of three games en route to possibly advancing to the championship game.
"We debated canceling the tournament in deference to the devastating tragedy in Moore, but were encouraged by Oklahoma City leaders and the Oklahoma City All-Sports Association to go forward," said Big 12 Commissioner Bob Bowlsby. " We believe the tournament can serve as a testament to the strong Oklahoma spirit and to the resiliency of the Oklahoma people."
The Sooners will now play their second two games against No. 8 Texas Tech and No. 1Kansas State at 9 a.m. Friday and 12:30 p.m. Saturday, respectively.
Winner's will meet in the regular scheduled title game at 1 p.m. Sunday.
