The twin-killing lifted Mount Mercy into first place in the North  Division standings with an 8-2 record in the conference. The Mustangs  are 15-7 overall for the campaign.

Mount Mercy trailed, 2-1, in the sixth inning of the opener when Mack  lofted a fly ball over the fence in left field with the bases loaded.  Tawny Menster (6-0) retired Clarke in the top of the seventh to finish  the victory.

Emily Oler belted a solo home run over the fence in center field to  help the Mustangs in Game 2. Madelyn Irwin (4-1) tossed a complete  game for the victory.
