Monmouth (7-3) got contributions all over the floor - Micah Seaborne, Deon Jones and Collin Stewart all scored 13 points and Justin Robinson added 12 points. The Hawks shot 50 percent (10 of 20) beyond the arc and outrebounded Georgetown 38-32.
Robinson's 3-pointer with 9:49 left in the first put Monmouth up 25-14 and a 10-3 run to end the half made it 39-27 at the break.
Georgetown never got it going after intermission. The Hoyas trailed by 10 with 2:27 to go, but made just one more basket as Monmouth hit 7 of 10 free throws down the stretch.
