Loyola led for much of the first set, going up 20-18 on a Jane Lukas kill before Mountain Hawks kills by Stephanie Slater and Jade Van Streepen tied the score.
A Greyhounds attack error and another Van Streepen kill made it 23-21 Lehigh, but a Mountain Hawks service error got Loyola back within a point, 23-22. Van Streepen put away another to give Lehigh set point, and despite another service error for a Loyola sideout, Taylor Carroll earned a first-set win for Lehigh with a kill.
The Mountain Hawks led throughout the entire second set and most of the third to earn the Patriot League victory.
Loyola continues their weekend trip to Pennsylvania's Lehigh Valley on Saturday afternoon with a 2 o'clock match at Lafayette College.
