Taylor Turnbow had 17 points and 12 rebounds to lead No. 7 LSU to a 61-40 victory over No. 24 Middle Tennessee on Wednesday night.
LaSondra Barrett added 10 points for LSU (2-0).
All-American forward Alysha Clark had 16 points and a game-high 20 rebounds for Middle Tennessee (1-1).
The Blue Raiders beat the Lady Tigers each of the last two seasons, including last year's game in which Clark scored 37. However, Middle Tennessee's hopes of a third straight win over LSU evaporated quickly.
After an early exchange of leads, LSU had its first double-digit lead by the 9:12 mark of the first half on a putback by Turnbow. The sophomore forward finished with career highs in scoring and rebounding.
LSU led 35-15 at halftime after Middle Tennessee's Jackie Pickel hit a 3-point shot from just across the midcourt line as time expired. It was the Blue Raiders' second basket in the final 13:25 of the half.
Middle Tennessee got as close as 16 points with 7:10 remaining on a shot by Clark, but the Lady Tigers' lead was quickly back up to 20 on a pair of free throws by Turnbow and a jumper by Barrett.
The Lady Tigers, who crushed Centenary 92-19 on Sunday in their season opener, held Middle Tennessee to 32.1 percent shooting and its lowest point total since scoring 32 against Tennessee-Martin on Jan. 5, 1998.
LSU senior guard Allison Hightower was helped to the locker room after leaving the game with 3:02 remaining. Lady Tigers coach Van Chancellor said Hightower, who finished with seven points, suffered from leg cramps but was otherwise OK.
