COLUMBIA, South Carolina (Ticker) -- South Carolina withstood Ernest Shelton's offensive assault by picking up its defense.
Shelton almost single-handedly gave Alabama a lead late in regulation, but Kerbrell Brown sent the game into overtime with a 3-pointer and scored five of his 16 points in the extra session as 24th-ranked South Carolina held on for a 90-82 Southeastern Conference victory.
The Crimson Tide trailed the entire second half until Shelton, who was not expected to play due to a left knee sprain, buried four consecutive 3-pointers. He sank his final 3-pointer with 2:50 remaining to give Alabama a 71-68 edge.
But the Gamecocks responded with 13 straight points as they held the Crimson Tide scoreless for more than 6 1/2 minutes.
"The key play was Kerbrell Brown's 3-pointer at the end of regulation," South Carolina coach Dave Odom said. "This was a gutsy win over a team that really wanted to win."
Brown buried a 3-pointer with 35 seconds left in regulation to force the extra period. He made a layup early in overtime before sinking a 3-pointer to give South Carolina (19-3, 6-2 SEC East) an 81-71 cushion with 1:50 to go.
Josh Gonner made seven free throws in the final 75 seconds and finished with 22 points for the Gamecocks, who shot 56 percent (32-of-57) from the floor and had five players in double figures.
"Maybe, slowly but surely, we are starting to put together something special here," Odom said. "Maybe we can look back on this at some point and be able to say that. We aren't there yet."
Carlos Powell scored 13 points and Mike Boynton, who opened overtime with a 3-pointer, added 12 as South Carolina made 14-of-25 shots from beyond the arc.
"Statistically, they are not a great 3-point shooting team," Alabama coach Mark Gottfried said. "They shot well tonight. They stepped up and made shots."
Shelton had 23 points and Kennedy Winston added five of his 20 in overtime as the Crimson Tide (11-8, 3-5 West) lost their fourth consecutive game.
Shelton was 5-of-12 from the arc and Winston was 4-of-6 as Alabama made 16-of-31 3-point attempts.
The Crimson Tide led much of the first half, but the Gamecocks bridged the halves with a 15-0 run. Brown opened the burst with a 3-pointer and added another before Boynton capped it with the first basket of the second half - a 3-pointer that gave South Carolina a 42-32 edge.
