Despite a shaky outing from Paige Parker on Sunday evening, coach Patty Gasso stuck with her ace — and it paid off.
Parker rebounded with a complete-game shutout in Oklahoma's 3-0 win against Tulsa, including 10 strikeouts.
The win sent Oklahoma to a super regional matchup at Auburn for a rematch of the 2016 College World Series.
The Sooners got started early in Monday afternoon's winner-take-all game as freshman Nicole Mendes smashed a leadoff first-pitch home run over the left field wall to give Oklahoma the early 1-0 advantage.
That score held as the Sooners escaped trouble in the second, third and fourth innings by getting a third out with runners on base.
