Alabama scored nine unanswered points to take a 42-41 lead at the 13 minute mark of the second half before an eight and a half minute stretch with just one Alabama field goal ended the Crimson Tide's chances for a third consecutive SEC road win.
LSU was cold to start the second half, hitting just five of 18 field goals early before finishing eight of 11 from the field in the remainder of the second half.
Alabama dropped to 10-7 overall and 3-2 in SEC play. LSU stayed undefeated at 4-0 in league play and is now 12-5 overall.
Richard Hendrix and Jermareo Davidson held their own with the highly touted LSU big men Glen Davis and Tyrus Thomas. Hendrix finished with 16 points and nine rebound and Davidson had 10 points and seven rebounds.
"Richard played really good," Alabama Head Coach Mark Gottfried said. "There were a few times when we get ball into J[ermareo Davidson], and he doesn't take a foul shot all night long, it's a little frustrating. It's hard to figure a guy can take 16 shots and not get to the line all day. I don't want to criticize officiating and get into all that. We hope we can do a better job of that and get to the foul line more in games."
Davis had 17 points and six rebounds for LSU, while Thomas had 10 points and 12 boards for LSU. LSU's leading scorer, senior guard Daryl Mitchell, had 19 points, two above his per game average.
Alabama played just seven players on the afternoon, and freshman Alonzo Gee scored just two points and spent most of the game on the bench with foul trouble. Jean Felix had 14 points for Alabama, emerging from a season-long slump and connecting on four of seven three point attempts.
"Our guys played hard. We could have done two or three things better," Gottfried said. " Our shot selection wasn't nearly as good as it could have been. We needed to settle down a little bit more. They've got to come back to our place in a couple of weeks and our guys will be excited about it."
Alabama gets its mid-week break this week before hosting Mississippi State at home next Saturday night at 6 p.m. That game will be televised on Fox Sports Net.
We need it [the open date]," Gottfried said. "The minutes we're playing; everything they've been through in the last couple of weeks on road three times, it's good to have a little time.
"We've won two on the road and now we've got to take care of business at home. We're going to stay positive and look at the things we can correct and keep going at it."
Overall, Alabama was 22 of 55 from the floor (40 per cent) compared to 26 of 61 for LSU (42.6 per cent). Alabama was five of 13 from three point range (38.5 per cent), LSU seven of 18 (38.9 per cent). LSU outrebounded Alabama 39-31. Alabama had 13 turnovers to LSU's 12.
