ALLIANCE -- The No. 4-ranked Ohio Northern softball team wrapped up its 2010 regular season with a doubleheader split Saturday afternoon at Mount Union.

The Polar Bears (35-3 overall, 17-1 Ohio Athletic Conference) won the second game 2-1 after dropping the opener 8-4 to the Purple Raiders (25-13, 13-5).

In Game 1 on Saturday, Senior All-American Tina Mangola blasted a 3-run home run to give ONU a 4-3 lead, but Mt Union rallied to tie the game at 4-4 and then scored four times in the bottom of the sixth to put the game away.

After MtU scored three times in the bottom of the first, freshman Chrissy Rankin had an RBI single in the top of the second to trim the deficit to 3-1.

Tina Mangola then drilled her home run to deep left field in the top of the third to give the visitors a 4-3 advantage.

But Mount tied it with a run in the fourth and won it with their 4-run sixth.

In Game 2, sophomore Jackie Mangola had an RBI double in the top of the first and Tina Mangola had an RBI single in the top of the third as ONU built a 2-0 lead.
