Jordair Jett gave No. 17 Saint Louis more than merely a 64-62 road victory against Massachusetts on Sunday.
His driving layup with 3 seconds left gave the Billikens (26-5, 13-3 Atlantic 10) their second successive outright conference title and snapped a three-game losing skid after a school-record 19-game winning streak.
Jett finished with 17 points, including the Billikens' last six of the game. Chaz Williams had 20 points and nine assists for Massachusetts (23-7, 10-6).
