The Tigers' victory at the Golden 1 Center in Sacramento, California was the program's first NCAA Tournament win since 1998 and just the 11th ever by a No. 15 seed in the tourney.
Princeton, which is back in March Madness for the first time since 2017 thanks to winning the Ivy League tournament, faced its largest deficit of 12 against Arizona with 11:50 remaining in the second half. But the Tigers ripped off a 24-8 run to close the game, which included holding the Pac-12 champions scoreless for the final 4:21.
The Tigers seized the lead with just over two minutes remaining on a layup from Ryan Langborg.
