(AP) – Collin Murray-Boyles scored 22 points and Morris Ugusuk hit a 3-pointer in overtime to give South Carolina the lead for good in a 91-88 victory over rival No. 25 Clemson on Tuesday night. South Carolina (8-3) appeared to have things under control, leading 76-69 in the final two minutes of regulation. But Chase Hunter had three 3-pointers down the stretch, including a bench shot with 0.3 seconds left that tied the game at 80 and forced overtime. Ugusuk hit a 3-pointer and Murray-Boyles followed with two foul shots to extend the lead. Duke transfer Christian Reeves had two foul throws with 3.7 seconds left to give Clemson (9-3) a 89-87 deficit. But he missed the first attempt and his line drive attempt failed. Jamarii Thomas was quickly fouled by the Tigers and managed to do both. Hunter’s floating 3-pointer at the buzzer failed as South Carolina won for the fifth straight time. Hunter finished the game with 27 points and Schieffelin had 23 points and 12 rebounds before exiting in overtime. Stute finished the game with 19 points for the Gamecocks. Clemson: The Tigers climbed into the rankings with a blowout 80-76 victory over top-five Kentucky earlier this month. But they have lost two in a row and are likely to drop out of the rankings. South Carolina: The Gamecocks are finding their way with five straight wins, including three over ACC opponents during that time. Ugusuk, a sophomore, was 1 of 7 before hitting his game-winning 3-pointer in overtime. South Carolina’s Nick Pringle had 18 points. He had 16 points and 11 rebounds for Alabama against Clemson in an 89-82 Elite Eight win last March. Clemson opens its ACC home season Saturday against Wake Forest. South Carolina plays Radford at home on Sunday.
