With 2:23 to play Auburn cut the lead into single digits when freshman guard Chris Denson hit a three to make the score 64-55.
The Tigers cut the gap to six when Adrian Forbes scored inside and was fouled. He made his free throw to cut the gap to 68-62, but that was a close as the Tigers could get as the home team took care of business at the free throw line to preserve the victory. Julysses Nobles was 8-8 at the foul line in the closing two minutes and five seconds for the Razorbacks.
Arkansas evened its record at 3-3 in the conference and improved to 13-7 overall.
Coach Tony Barbee's Tigers fell to 0-6 in the SEC and 7-13 overall.
"We played well enough in the first half," Barbee said. "We kept it close. We kept it within striking range and then we come out in the second half and go ice cold--almost lifeless. Then you are scrambling for your life trying to catch up and get back into the game."
On the plus side the Auburn coach said he liked the fight his team showed in coming back after the horrible start in the second half. He also liked the production of backup center Adrian Forbes, who contributed his Auburn high of 11 points and three rebounds for the Tigers. The juco transfer made five of his six shots.
Ross led the Tigers in scoring with 15 points and freshman guard Allen Payne added 13 points.
"I told our guys to keep fighting, keep fighting--that other team was going to have a letdown," Barbee said in discussing his team's comeback. It is a game of runs. Our run came, but we just couldn't get over the hump."
Neither team could make a run in the first half. Arkansas led 34-30 as the Razorbacks got 10 points from Rotnei Clarke, who tied for game-high scorer with Nobles at 16 points.
