Sophomore guard Andre Malone led the Tigers in scoring with 17 points and sophomore center Rob Chubb scored 12 points.
The Tigers had, by far, their best shooting night of the young season hitting 51.2 percent of their field goals as they improved to 2-4.
Georgia Southwestern, which plays in the Division II?Peach Belt Conference, fell to 3-2 with the loss. Both of the Hurricanes' losses came to Division I teams.
"I thought Rob set the tone tonight," Barbee said of the center. "Chubb dives like three times on one possession. The bench goes crazy, I go crazy. We get the ball and all of the sudden we are fired up with a 13-1 run to start the game. For the most part we sustained that for 40 minutes."
"Good offense, good defense, that is all great and fine, but it is the extra effort, all-out, everything you have got for every second on the floor that matters," Barbee added. "You have to compete every possession because our margin for error is small."
Barbee said the Tigers had "gotten after it" in practice after a disappointing loss to Jacksonville on Saturday in which he didn't like his team's intensity. "It has been all about the extra effort plays."
The Auburn head coach also liked his team's defense, which forced 23 turnovers, 12 more than the Tigers committed.
"I thought we played harder on the defensive end," Barbee said. "We were on our toes instead of our heels. Offensively, we took care of the ball, but they didn't press us."
Chubb said he is gaining confidence the more he plays after seeing very little playing time last season as a freshman. He pointed out that almost nobody else on the floor for the Tigers played much last season.
"We are still learning to play together as a team," Chubb said. "It is going to get better with time."
Kenn Gabriel scored six points and added four rebounds for the Tigers.
In addition to good shooting from the field, Auburn made 14-18 free throws to help the Tigers cruise to the victory after leading by just 32-26 at halftime.
Auburn's bench was a major factor, outscoring the Hurricanes' subs 27-0. Georgia Southwestern coach Mike Leeder had watched Columbus State, a team from the Peach Belt Conference, defeat the Tigers in an exhibition game. "I think Auburn is much improved from where they were at when I saw them on tape in exhibition against a couple of other Division II?teams," he said.
The Tigers will return to action on Sunday with a home game vs. Arkansas--Pine Bluff.
