Buoyed by an ultra-efficient shooting day from deep, Georgia (18-12, 12-6), which connected on 9-of-15 triples, kept LSU (18-12, 9-9) at bay, holding off numerous Tiger comebacks to secure a 69-61 victory on Saturday.
The visiting Dawgs were paced by guard Kenny Gaines, who posted 20 points and made six of his seven three-point attempts. UGA also got 21 points and nine rebounds from backcourt mate Charles Mann.
LSU, which celebrated Senior Day in the PMAC, were led by a game-high 22 points from senior Andre Stringer, who scored 13 of those in the opening 20 minutes of play.
"You always want to keep winning as long as you can. To take a loss today, it really hurt, especially sending my guys Andre and Shavon [Coleman] out with losses," said Johnny O'Bryant, who had only five points and eight rebounds. "That's not something we're proud of."
Johnny Jones' Tigers, which never led in the second half, ended the regular season at .500 in the SEC for his second straight year at the helm of the program.
With the loss, LSU finishes tied for sixth in the SEC with Ole Miss and Missouri, but due to a tiebreaker the Tigers will carry the seventh seed into the conference tournament, which tips off in Atlanta Wednesday night.
The Bayou Bengals will play Alabama, the 10-seed, Thursday night at 7 p.m. EST in the Georgia Dome. It is a single-elimination tournament.
