Earnest Ross, who played two seasons at Auburn, scored 23 points and added two rebounds off the bench in his first game against his former team. His teammate, Keion Bell, scored 24 points for Missouri, which improved to 16-5 for the season and 5-3 in the SEC.
Missouri hit 54.5 percent of if its field goals, a statistic that did not please Auburn coach Tony Barbee. "You can be a really good team when nobody is guarding you--it is easy to score," he said, calling his team's defense the worst in the SEC.
"We just couldn't guard the ball," Barbee added. "It wasn't like we were making them go wide, two or three dribbles and you can help. It was straight line drives down the middle of the lane and it is hard to help."
Auburn made just 35.8 percent of its field goals, hitting 19-53. The Tigers connected on 7-22 threes and were on target at the foul line making 32-36.
Missouri held a slim edge in rebounds, 32-31, and made 6-16 threes and 25-32 free throws. Missouri had 11 turnovers while Auburn finished with 12 turnovers.
Missouri coach Frank Haith had praise for the way his team played. "I thought we really turned down some good shots for some great shots, and that was good to see," he said.
"We have to bottle what we have when we play at home and take it on the road," the coach added. "We have good chemistry when we play at home, sharing the ball, and we have to get that done on the road."

Ross On Playing Against Auburn: Asked about playing against his former team, Ross said his goal was to "just to go out there and play hard."
"It was a personal thing when I stepped on the floor," he added. "I know most of those guys so it was more of a friendly rivalry, I would say, but most of all just going out there and executing what the coached asked of us. It was just another game we have on our schedule to win and with the team at hand we have to go out there and execute what they ask of us. Tonight we did that as a team."
