NEW YORK — Sterling Gibbs hit a step-back jumper at the buzzer and Seton Hall stunned No. 3 Villanova 64-63 in a thrilling Big East quarterfinal Thursday, a loss that could cost the Wildcats a No. 1 seed in the NCAA tournament.

Eugene Teague had 19 points and 12 rebounds for the eighth-seeded Pirates (17-16), who advanced to the Big East tournament semifinals for the first time in 13 years. Josh Hart came off the bench and scored 18 to lead the top-seeded Wildcats (28-4), beaten only twice in 18 regular-season conference games while winning their first outright Big East title since 1982.

NO. 4 ARIZONA 71, UTAH 39: LAS VEGAS — Nick Johnson scored 14 points, T.J. McConnell added 13 and No. 4 Arizona overwhelmed Utah defensively in a rout that tied for the most lopsided game in Pac-12 tournament history.

NO. 5 LOUISVILLE 92, RUTGERS 31: MEMPHIS, Tenn. — Chris Jones scored 15 of his 18 points in the first half, and fifth-ranked Louisville routed Rutgers in the quarterfinals of the American Athletic Conference tournament.

The Cardinals (27-5) have won three straight and 10 of their last 11 as they look for a third straight tournament title even if they’re only in the American for one season.
