Tennessee had a 3-1 lead with Oklahoma down to its final out when Ella Parker hit a walk-off three-run home run, her second of the game. Ace pitcher Karlyn Pickens had spun a fantastic game to that point, finishing the game with four earned runs on four hits and four walks with eight strikeouts across 6 2/3 innings pitched.
