Alex Caruso added 14 points, and Kourtney Roberson and Fabyon Harris had 11 apiece for Texas A&M.
The Auburn Tigers (9-23) wrap up the season losing their last 10 games and now have lost 11 straight in Nashville. Coach Tony Barbee has yet to win a tournament game in his first three trips. Frankie Sullivan scored a team-high 19 points, and Chris Denson added 15 points.
Barbee said before the season he thought this would be his best team yet at Auburn. Asked how he could misjudge his Tigers so much, Barbee said he didn't and that a team's record doesn't indicate why the season turned out this way.
"Just disappointing," Barbee said. "We had opportunities in more than our fair share of games this year and just couldn't get over the hump."
Turner showed no ill effects early from his broken finger. He hit three of his first four shots and had nine points by halftime. The senior guard said after the game his finger did hurt at times, and Kennedy said he thinks Turner got frustrated a bit in the first half.
"They kind of chopped at him two times, but he did a good job of getting his composure and playing through it," Kennedy said.
The Aggies both outshot and outrebounded Auburn. They hit 44.9 percent (22 of 49) compared to 40 percent (20 of 50), and they had a 9-0 scoring edge off second-chance points while outrebounding Auburn 36-24.
Both teams started shooting the ball well, and Auburn hit three 3-pointers, the last by Noel Johnson for a 13-10 lead with 16:15 to go. Turner answered with a 3 and a jumper to put the Aggies ahead to stay with 15:14 left. That was the start of 15 straight points by Texas A&M, the last a layup by Young for the Aggies' biggest lead of the half at 24-10 with 11:28 remaining.
