Needham hit the 3-pointer for a 59-57 lead, and then drew an offensive foul on the Hawks' ensuing possession. Fairfield inbounded the ball to Needham, who was fouled and hit 1 of 2 foul shots, and Jones' buzzer-beating 3-point attempt clanged off the rim to end the game.
Needham finished with a game-high 24 points.

The win was Fairfield's first over Saint Joseph's since 1977-78, ending a 10-game losing streak in the series.
