Coach Tony Barbee's team got 14 points off the bench from freshman Brian Greene along with a double-double from senior center Rob Chubb, who scored 16 points and pulled in a team-leading 10 rebounds. Frankie Sullivan added 17 points to lead the Tigers in scoring.
For Greene it was his top scoring game as a Tiger. He was a perfect six-of-six from the field in 28 minutes of action as he stepped up with the Tigers missing guards Chris Denson and Jordan Price with injuries.
The freshman made a pair of treys, blocked a shot and added one assist. "We went through a lot of adversity in this game," Greene said. "We were short-handed so this was a really good win."

Bruce Ellington, who paced the Gamecocks in scoring with 18 points, had an opportunity to tie the game, but missed an off-balance three-point shot and Auburn got the rebound and ran out the clock before the home team could foul.
Barbee said the Tigers planned to foul after calling a timeout with 9.3 seconds left and the Gamecocks having the ball, but noted that wasn't necessary. "They had some problems executing what they were trying to run and they got forced into a bad three-point shot down in that corner," the coach said.

"We are still not a finished product yet, but we are getting closer to what is important, which is our identity," the coach said. "That is grittiness and toughness. That shows up when adversity hits.
"We weren't so tough early in the season," Barbee added. "We let adversity effect us. We haven't in that little run we have been on.
"It was a physical game," the Auburn coach pointed out. "You know it is going to be like that when you play against a Frank Martin coached team. We got in some foul trouble, adversity right there, but we had some guys step up."
Rob Chubb pulls in one of his 10 rebounds.
