The Red Storm fell to 0-1-1 on the year while SPU improved to 2-1-0.
Seattle Pacific struck first in the 38th minute to take a 1-0 lead. The Falcons got the goal when Emma Holm netted a shot just under the crossbar from nearly 30 yards out straight away.
"We came out and struggled to meet SPU for pace in the first half," head coach Kacey Bingham said afterwards. "Second half we came out much stronger and held them to minimal shots."
The Red Storm's first serious chance came early in the second half, when junior Kimberly Thurman (Sandy, UT/Alta) put a shot on goal that was cut short by SPU keeper Natalie Harold to keep the home team ahead.
The Falcons then made it 2-0 in the 70th minute when Josie Greybeal cross the ball to the right side of the box. Demi Whatley picked up the cross and snuck a shot by DSU goalie Stacie Gubler (Las Vegas, NV/Palo Verde) inside the right post for her first goal of the season.
Laura Moore capped the scoring with her third goal of the season - a diving header from the left post in the 82nd minute - giving Seattle Pacific a 3-0 lead.
Megan Marchbanks (Springville, UT/Springville) had a pair of one-on-one chances for the Red Storm late, but a shot with 12 seconds remaining in the match was snared by Harold to ensure the shutout.
Overall, Seattle Pacific outshot the Storm, 19-4. Gubler made five saves for DSU, while Harold recorded two.
Bingham added: "We missed two one-on-one opportunities. In the future, we need to finish those chances to compete with top ranked teams."
