OKLAHOMA CITY — The Bedlam softball rivalry reached the biggest stage Friday night at the Women’s College World Series. The overflow crowd of 9,820 at USA Softball Hall of Fame Stadium got to see Oklahoma and Oklahoma State meet for the first time in the WCWS.

The Sooners rolled to a 6-1 victory, their 24th in a row over the Cowgirls since 2011.

OU plays at 2:30 p.m. Sunday against an opponent to be determined Saturday. The Sooners one more victory to reach the championship series for the fifth time in eight seasons and keep their hopes alive for their third national championship in four years.

OSU’s fight through the losers bracket begins against Washington (50-8) or Minnesota (46-13) at 6 p.m. Saturday in an elimination game. The Huskies and Gophers meet at 11 a.m. with the winner advancing to face the Cowgirls.

The Sooners (56-3) jumped on OSU ace Samantha Show in the top of the first inning. Jocelyn Alo laced a two-run single and Shay Knighten singled to score Grace Green before OSU (45-16) even got in the batter’s box.

Show has been on an epic tear since the NCAA Tournament began and that continued in the 2-1 victory over Florida on Thursday, when she homered twice and dominated in the circle in opening victory.

The Ruthian-like run came to a halt Friday. Show lasted four innings, giving up three runs on six hits, walking one and striking out two. At the plate, Show went 0-for-3 and struck out twice.

OU pitcher Giselle Juarez struck out 11 over six innings.. She gave up an RBI single to Michaela Richbourg in the bottom of the first inning to put OSU to within 3-1, but even a two-run deficit can seem insurmountable against the Sooners. Heading into the game, the Sooners hadn’t allowed more than two runs since an 8-3 victory at Iowa State on April 26.

OU added three more runs in the sixth. OSU reliever Logan Simunek walked OU’s Falepolima Aviu and Alo with the bases loaded and hit Caliegh Clifton to bring in another run.
