Jose Romo-Martinez connected on field goals of 25 and 30 yards to give the Hornets a 6-3 lead midway through the second quarter, but Kehoe brought Delaware back, running 21 yards for a touchdown before hitting Owen Tyler out of the backfield for a 24-yard score to take a 16-6 lead at intermission.
Kehoe found Thyrick Pitts with a back-shoulder throw from 14 yards out to make it 25-6 and Brian Dennis blocked a Fidel Romo-Martinez punt, scooped up the loose ball and ran 14 yards for the touchdown early in the fourth quarter.
Tylik Bethea threw a 10-yard strike to Bizzet Woodley for the Hornets with 3:30 left to create the final score.
Jake Roth had field goals of 38- and 33-yards, but was 1-for-4 on PATs, missing once and having two more blocked.
