Oklahoma's 39-game winning streak was enough to earn the No. 1 seed in the NCAA Softball Tournament.
The Sooners (49-2) will host Wisconsin, Notre Dame and UMBC in the Norman Regional. The tournament field was unveiled Sunday night on ESPN2.
Oklahoma will begin the tournament as the No. 1 seed for the first time since 2013.
The Sooners will be vying for the fifth national championship in program history, and their fourth in the last seven years.
