Shenandoah (18-19, 7-11 ODAC) was a 4-2 winner in the nightcap after the Wasps (23-13, 13-5) took game one, 8-2.
The Hornets keep their ODAC Tournament hopes alive with the split. SU has one more league win than eighth place Roanoke and also holds the head-to-head tiebreaker over the Maroons. RC has league games remaining with Randolph-Macon and Eastern Mennonite and would need to win two of those four games in order to pass Shenandoah.
A six-run fourth for E&H erased a two-run Shenandoah lead on its way to the 8-2 victory.
The Hornets scored their runs on a Meghan Stout sacrifice fly in the first and a Carrie Robinson triple in the second. Robinson's triple into the left-center gap scored Maryann Hollen, who had singled up the middle to lead off the SU second.
Freshman Megan Scalley (6-7) was tagged with the loss after giving up seven runs (three earned) on five hits and six walks in 5 1/3 innings.
Cameron Derr (9-5) struck out 10 and held Shenandoah to five hits in the complete game performance.
Shenandoah took advantage of three Wasps errors to score three runs on just one hit in the fifth inning and salvaged the split with the 4-2 win.
Sierra Beaty had the lone hit in the frame, leading off with a single to right, before E&H dropped a pair of pop flies and committed one throwing error that allowed the three runs to cross the plate.
Carrie Robinson (9-8) got the win in relief, pitching a scoreless fifth, before Scalley earned her first save by getting the final six outs of the contest.
Tiffany Cole took the loss for the Wasps. She gave up four runs (just one earned) on three hits.
