Shenandoah (24-11, 13-9 ODAC) finishes tied for third in the league with Ferrum and Virginia Wesleyan thanks to its second win in as many days over Guilford (15-24, 8-14), but earns the No. 3 seed on tie-breakers.
The third seed means that SU hosts sixth-seed Hampden-Sydney this weekend in a best-of-three first round series.
This is the second straight year that the Hornets and Tigers will meet in the first round of the ODAC Tournament.
Junior Reeves Lowry was dominant in throwing the squad's second complete game of the weekend. Lowry scattered eight hits, allowing only a ninth inning run, and struck out nine while not walking a batter.
The right-hander is now 3-3 on the season.
Shenandoah scored single runs in the first, second and third innings before Tristan Baker capped off his day with a two-run double in the seventh.
Grant Thompson scored the squad's run in the second by coming home on a wild pitch. Thompson had led off the frame with a single through the left side before moving to third on a pair of groundouts.
Baker and Nussman both finished 2-for-4.
Parker Brann (0-4) took the loss for the Quakers. He allowed one run on two hits and one walk in one inning of work.
Shenandoah takes to the road tomorrow for a 4 p.m. non-league contest at Susquehanna.
