Jordan Gathers hit a 3-pointer at the buzzer, and St. Bonaventure stunned No. 18 Saint Louis 71-68 in the quarterfinals of the Atlantic 10 tournament Friday.
The ninth-seeded Bonnies (18-14) came into the tourney on a four-game losing streak before beating La Salle on Thursday. They trailed the top-seeded Billikens by 10 points at halftime but rallied behind a swarming defense and clutch 3-point shooting.
Saint Louis big man Dwayne Evans, who had hit three 3-pointers all season, made a 3 over 7-foot Youssou Ndoye with 20.9 seconds left to tie the game at 68-68.
Matthew Wright and Charlon Kloof led St. Bonaventure with 22 points. Gathers had just two points before making the winner.
Mike McCall scored 21 for Saint Louis (26-6), which lost its first game in its attempt to defend its A-10 tournament title. The Billikens have dropped four of five.
