Mankato scored all five of its runs in the second inning of the nightcap. Four came home on Julia Bastian's grand slam off Breanna Swint, who threw a six-hitter and struck out four.

UMD rallied with three runs in the bottom of the seventh, including Taylor Koehnen's RBI single and back-to-back homers by Lauren Oberle and Bren.

Kayla Christopherson singled in a run and Toni Bishop walked in the eventual winning run in the 10th. Olivia Howe drove in two runs and had two of the seven bases on balls issued by the Eagles (14-14, 4-4), who scored one run in the bottom of the 10th.

The Saints (13-13, 5-3) fell 5-2 in the opener despite losing pitcher Maggie Schley hitting a two-run homer to open the scoring.

• Wisconsin-Superior totaled 30 hits in a 10-0 and 12-1 doubleheader sweep over Martin Luther College in UMAC action at NBC Spartan Sports Complex in Superior.
