Auburn has found new life in Nashville.

Down 10 points at the half to Texas A&M in the SEC Basketball Tournament, the Tigers reeled off a 16-1 run to open the second and never looked back, upsetting the Aggies 66-59 to advance.

The tournament's No. 13 seed now finds itself in the quarterfinal round against No. 4 seed LSU. Auburn and LSU split the regular season series, as the road team won both times.

"This becomes the third team in 30 years of Auburn basketball history to win a couple games and advance in the tournament," said Tigers head coach Bruce Pearl. "Now maybe that's not something that you want to brag about, but those are the facts. And those facts matter to these guys right here."

Auburn entered the week on a six-game losing streak before winning its opening round game against Mississippi State Wednesday night, its first in the tournament since 2009.

Senior KT Harrell paced the Tigers (14-19) with 25 points and five rebounds and Auburn improved its field goal percentage from 28 percent in the first half to 40 in the second. Cinmeon Bowers finished with 10 rebounds and eight points after a lackluster performance against Mississippi State.

"(Pearl) just came in the locker room mad, so when he gets mad, it's time to go," Bowers said when asked about the second half run. "We can't back off. We got a steal and it got us going."

Alex Robinson and Alex Caruso had 11 points each for the Aggies (20-11), who are hoping to earn a bid to the NCAA Tournament.

"Really disappointed that we didn't play like we're capable of playing," said Texas A&M head coach Billy Kennedy. "Some turnovers in the beginning of the second half, again for whatever reason our energy level, it wasn't where it needed to be. It's kind of hard when you don't execute offensively and give teams opportunities to get easy baskets, then they got going a little bit. You got to give Auburn credit. They got going a little bit and their confidence was better than ours."
