Shenandoah (19-4-1, 15-2 ODAC) was a 14-4 winner in the opener before winning game two 24-10 over the Wasps (7-25, 3-15) in the nightcap.
SU banged out 21 hits and got five-hitter from junior Darrell Thompson (3-1) in winning the opening game while five pitchers combined for the game two victory.
In the opener, the Hornets scored in every inning except the fourth and seventh with all nine hitters in the lineup getting at least one hit and seven posting at least two each.
J.J. McDaniel, the current ODAC Player of the Week, led the offensive attack with four hits in four at-bats while driving in two runs.
Thompson allowed four runs (just one earned) on five hits and two walks in 8.0 innings of work. He struck out five.
Coach Kevin Anderson's club jumped out to an 8-0 lead but needed a four-run sixth to finally pull away from E&H.
All nine hitters again hit safely in the contest with Ryan Mossman getting six hits in seven at-bats and Wilt going 4 for 5 with 5 RBI.
Arens, Pardo, Paul and McDaniel all had at least two hits in the contest with McDaniel hitting a home run.
With the sweep, SU is now seven games ahead of seventh place Eastern Mennonite in the loss column with four league games remaining. The top six teams make the ODAC Tournament and the Hornets are guaranteed a spot in the tournament.
SU's magic number to clinch the No. 1 seed is down to three.
Shenandoah returns home on Monday for a 4 p.m. non-league contest against Mount Aloysius.
