Jamal Wilson's last-second layup after rebounding a teammate's miss lifted Rhode Island past Charlotte 71-70 Saturday.
Those were the only points for Wilson, who had scored just 11 previously this season for the Rams (16-9, 7-4 Atlantic 10 Conference).
After Marquis Jones' layup with 12 seconds remaining brought Rhode Island within 70-69, Nikola Malesevic stole the ball back. Jones missed a layup and Akeem Richmond's 3-point try was put back by Wilson.
The 49ers (10-14, 2-8) led 40-23 early in the second half before a 20-4 run, including three 3-pointers by Richmond, brought Rhode Island within one, 44-43 with 10:50 left in regulation.
Richmond led the Rams with 20 points, including six 3-pointers, and Malesevic had 19.
Chris Braswell, whose two free throws with 8 seconds left in regulation sent the game to overtime, and Derrio Green each scored 17 for Charlotte.
