South Carolina won its second straight game at the Southeastern Conference tournament, upsetting Arkansas 71-69 on Thursday behind 17 points from Sindarius Thornwell and likely knocking the Razorbacks out of the NCAA tournament.

The Gamecocks (14-19), whose only hope of making the NCAAs is to win it all in Atlanta, advanced to the quarterfinals Friday against Tennessee. Arkansas (21-11) will likely have to settle for an NIT berth.

After South Carolina went ahead 70-69 on Brenton Williams' free throw with 53 seconds remaining, Arkansas squandered two chances to reclaim the lead. Rashad Madden missed a floating jumper in the lane with 33 seconds left, and Bobby Portis couldn't connect in the lane with 3 seconds to play.

The Gamecocks missed three of their last four free throws, giving Arkansas one more opportunity. Madden's desperation heave from just inside the half-court line bounced off the back of the rim.
