Avery Hodge flew out to left field to end the third, and Kierston Deal entered the game for May in the fourth.

Oklahoma had a great opportunity to respond in the sixth. 

Boone singled and then advanced to second on a wild pitch, and Jennings’ walk put a pair aboard with one out. 

Brito was unable to play hero, as she popped out into foul territory and then Parker flew out to left field, leaving plenty of work to do even before the disastrous seventh inning.
