No. 5 Oklahoma (16-3) won both games at its Courtyard Marriott Tournament in run-rule fashion Saturday afternoon.
Oklahoma 10, Missouri State 0 (5 innings)
Paige Parker became the first player in OU history to throw two perfect games in one season as she retired all 15 MSU batters she faced. She struck out three and needed only 64 pitches to improve to 6-2 on the season. Parker joins Jennifer Stewart as the only two Sooners to throw multiple perfect games in their careers.
At the plate, Lauren Chamberlain went 2-for-3 with six runs batted in. She hit a three-run double in the third and hit a walk-off, three-run homer in the fifth. It was the 80th home run of her career, making her the sixth player to reach the 80-HR plateau in NCAA DI history.
Oklahoma 9, Samford (6 innings)
