Freshman Jermaine Couisnard hit a 3-pointer as the buzzer sounded and South Carolina rallied from 14 points down in the second half to stun 10th ranked Kentucky 81-78 Wednesday night at Colonial Life Arena. 

Couisnard had a career-high 26 points, including his game-winner that banked in for the Gamecocks (9-7, 1-2 Southeastern Conference). When it went through the net, Couisnard and his teammates ran around the court in celebration as the fans erupted in cheers.

Moments earlier, Immanuel Quickly banked home a shot with 4.1 seconds to go that tied the game at 78. Quickly led Kentucky (12-4, 3-1) with 20 points.

Keyshawn Bryant scored 15 points for the Gamecocks, who had 4 players in double figures.

Kentucky led by 14 less than 4 minutes into the second half and was still up 54-41 on E.J. Montgomery's 2 foul shots with 11:41 left.

That's when Justin Minaya started a 27-14 run over the next 7 minutes that ended with Couisnard's basket off the glass to tie the game at 68-68. 

After Ashton Hagans put Kentucky up again with 2 foul shots, Minaya answered with a 3-pointer to put the Gamecocks ahead and send the crowd into pandemonium. 

Minaya added 2 more baskets between a drive by A.J. Lawson and South Carolina was ahead 76-71 with 1:46 to go.

Kentucky tied it a final time on Quickly's jumper after Lawson missed 2 foul shots with a chance to seal the game.

South Carolina ended a 3-game losing streak against Kentucky. The Gamecocks past 5 wins over the Wildcats since 2009 have all come at Colonial Life Arena.

They won despite missing their first 10 shots and shooting less than 25 percent from the field.

The Gamecocks will play its next 2 contests on the road, beginning Saturday at Texas A&M (8-7, 2-2 SEC). Tip for the contest is set for 1 p.m.
