Philadelphia ? Gonzaga needed overtime to deny Saint Joseph’s its biggest win in four years.

Matt Bouldin scored 16 points, including the go-ahead free throws in overtime, to help No. 19 Gonzaga hold off Saint Joseph’s, 70-65, on Thursday night.

Austin Daye scored 17 points and David Pendergraft had 13 for the Bulldogs (6-1), who needed a late rally in regulation for the thrilling win and to take the overall series lead in the battle of the small Jesuit universities.

Pat Calathes led the Hawks (3-2) with 24 points and Ahmad Nivins scored 14. The Hawks battled back from a 17-point deficit in the first half to take the lead late in the second.

Nivins missed two free throws with 1:32 left in overtime and the game tied at 61.
