The Tigers (8-8, 3-0 Ivy League) converted 8 of 14 tries from beyond the arc, while Cornell (14-7, 4-1) made just 2 of 17. Overall Princeton shot 50 percent from the field, while holding the Big Red to 32 percent.
Louis Dale, with 12 points, was the only Cornell player in double figures.
The Tigers never trailed and were tied only once, at 4-4.
The Big Red made a run to cut what was once a 14-point lead to three at 34-31 as late as the 12-minute mark of the second half. But Princeton went on a 17-6 run to regain what was then its largest lead and cruised from there.
