Yannetti keyed a two-run, two-hit fourth inning as the Mustangs knotted the game at 2-2 when her double to the right-field gap scored Jessica Rodriguez and Maranda Bishop.

MSU took then took the lead in the fifth inning Kristen Stonecipher's run-scoring single to left plated Lindsey Voigt, who had reached on a walk and advanced to third on a pair of Johnson wild pitches.

But Stonecipher would leave the game with an injury after she was called out trying to stretch the single into a double.

After the Savage Storm tied the game in the bottom of the frame, the Mustangs regained the lead in the top of the sixth when Alyson Reynolds' single to right scored Yannetti, who had reached on her third-straight double.

But Southeastern rallied for a run in the bottom of the sixth to send the game to extra frames.

The Mustangs again took the lead in the top of the 10th when Voigt scored on Amanda Potysman's groundout to third.
