Schedule and results
On December 29, Princeton defeated number 17-ranked Arizona State after Richmond Aririguzoh made a pair of free throws with 24.8 seconds left to provide the final 67–66 margin of victory. It was Princeton's first win over a ranked opponent since defeating the 25-ranked 2011–12 Harvard Crimson on February 11, 2012, and the school's first win over a top-20 opponent since head coach Henderson was a player on the 1995–96 Princeton team that upset the UCLA Bruins in the 1996 NCAA Division I men's basketball tournament.
