LSU (1-0) used the bench well, having all 15 players play at least six minutes and 14 players score at least two points.
"We talked to our kids in the locker room about our strength in numbers," LSU head coach Pokey Chatman said. "We were able to play the entire bench and relatively do a decent job of taking care of the basketball and executing in the half court offense. It is nice to see those kids step up and gain some confidence against a quality opponent like Maine."
The only LSU player not to score, Khalilah Mitchell, added a team-high four assists to the victory.
All-American Seimone Augustus led LSU with 17 points, including 15 in the first half. The Baton Rouge native also finished with four rebounds and four assists in 22 minutes of play.
Freshman Sylvia Fowles collected her first career double double with 13 points and 11 rebounds in 20 minutes of play off the bench, while fellow freshman Quianna Chaney connected on four three-pointers to finish the game with 12 points.
The win earned Chatman her first official victory as head coach at LSU. Chatman led the Lady Tigers to a 15-5 mark last season as acting head coach after stepping in for the ill Sue Gunter.
LSU, on the night they lowered the Final Four banner from the Maravich Center rafters commemorating the program's first appearance in the NCAA Final Four in 2004, shot 49.3 percent from the floor and outrebounded Maine 44-28.
Monica Peterson led Maine (0-1) with 12 points and seven rebounds, while Ashley Underwood added 10 points off the bench.
The Lady Tigers will face Arizona State in Friday's championship game at 7 p.m. CST. The Sun Devils defeated Virginia 60-50 in the opening game of the tournament on Thursday. Maine will face Virginia in the consolation game at 5 p.m.
Lady Tigers open with 81-50 win over Maine
