George Washington was in control for much of the game, taking a 13 point lead into the break and extending it to as many as 20 with six and a half minutes remaining.
However the Hawks would battle back down the stretch, cutting the lead to four on the strength of an 18-4 run before the Colonials would regain their composure and put the game away.
DeAndre Bembry led Saint Joseph's (6-6. 0-1) with 22 points and eight rebounds. Chris Wilson added 13 points and nine rebounds for the Hawks.
