Oklahoma's softball team will begin their attempt to repeat their national championship from last season against the team that beat them in the 2012 Women's College World Series finals.
OU will face Alabama in the opening round of this year's WCWS at 8:30 on Thursday night at ASA Hall of Fame Stadium in Oklahoma City.
Oklahoma started slowly this season, but have been playing well since mid-March, winning 32 of their last 35 games.
OU head coach Patty Gasso says getting back to the WCWS is a great reward for all her team has been through, battling injuries and inexperience in the pitching circle.
They'll face an Alabama team that failed to make the WCWS last season after winning it all in 2012.
