CHARLESTON, S.C. (AP) — Christian Keeling scored 29 points and grabbed 10 rebounds and Charleston Southern held off Longwood's late rally for a 79-74 victory on Tuesday night in the first round of the Big South Championship.

No. 8 Charleston Southern (12-18) travels to face top-seeded Winthrop in a quarterfinal matchup on Thursday. It was the first conference tournament win for the Buccaneers since they beat Campbell in a first-round game on March 5, 2014. Ninth-seeded Longwood (6-24) has lost 16 straight.

Isaiah Walton and Khris Lane scored 24 points apiece to lead the Lancers.

The Lancers used a 17-5 run, capped by Lane's dunk, to pull to 77-74 with 20 seconds to play. Patrick Wallace missed a pair of free throws on the Buccaneer's next possession, but Lane missed a 3-pointer with eight seconds remaining. Wallace, who finished with 10 points, then added two free throws to seal it.

The Buccaneers snapped a two-game losing skid against the Lancers in the past two conference tournaments.
