CHARLESTON, S.C. -- Canyon Barry had 19 points and College of Charleston used a big first-half charge to hand LSU its third consecutive loss, 70-58, on Monday night.
The Tigers (3-3) were looking for a soft place to recover after falling to Marquette and North Carolina State last week. The Cougars (4-2) proved they were not about to concede anything to LSU's dynamic freshman tandem of Ben Simmons and Antonio Blakeney.
Barry scored 12 of his points in the opening half as Charleston pulled in front 41-17 on Payton Hulsey's foul shots to start the second half.
LSU sliced things to 63-56 on Jalyn Patterson's 3-pointer with 1:08 to play. That was as close as the Tigers could get.
Simmons led LSU with 15 points and 18 rebounds, his fourth double-double in six college games. Blakeney missed all nine of his shots, the team's leading scorer ending with one point.
Fans rushed the court when the clock ran out, celebrating the Cougars latest win over Power Five league team. Charleston has beaten North Carolina, South Carolina and Tennessee in the TD Arena's seven seasons.
The Cougars pushed the pace early, made outside shots and played strong defense on Simmons and Blakeney.
The two, who came in averaging better than 32 points a game, would end up with just 4 in the first 20 minutes on combined 1-of-10 shooting.
LSU went through several scoreless stretches, the longest lasting more than six minutes as the Cougars pulled away.
Charleston used a 13-0 run midway through the first half to turn a one-point lead into a 24-10 margin.
Barry had a 3-pointer in the surge and finished the half with 12 points.
