Harrell fought through two big chances for the Cowgirls, but shut the door when she needed, picking up her first shutout of the season. She went the distance, allowing five hits and a walk while striking out two.

After a scoreless first three innings, Tech strung together a few hits and used some miscues by OSU to plate three runs. Dani Anderson led off the inning by getting hit by a pitch and moved to second base on Courtney Liddle’s single to left, Tech’s first hit of the game.
