The Tigers clamped down on the Aggies, which had won two straight and four of six, limiting A&M to 16-of-52 shooting (30.8%) shooting from the field.
"Really impressed with our team - I thought we did a great job defending tonight on the perimeter, inside," LSU coach Johnny Jones said postgame. "We challenged them, made sure that we didn't give up driving lanes, rebounded the ball extremely well, something that we needed to do."
Martin led the way for the Bayou Bengals, showcasing a consistent outside game that featured 4-of-5 shooting from beyond the arc and 7-of-9 shooting from the floor.
"I think it really helps that he's patient. He's shown that. He shot a great percentage from the field tonight, hit some big threes out there," explained Jones. "He didn't go shot-hunting. I thought he was patient and took what the defense gave him tonight."
The rest of LSU's frontline was solid, as always. Johnny O'Bryant posted 15 points and nine rebounds while Jordan Mickey had eight points, six rebounds and five blocks.
After falling behind 15-7 with 13:08 left in the first half, Johnny Jones' crew went on a deflating 21-0 run, stymieing the Aggies and holding the visitors without a point for 10 minutes and one second of play.
But A&M didn't quit. The Aggies proceeded to make a 7-0 run of their own, eventually pulling to within six, 30-24, at the half.
LSU soon distanced itself in the second half, stretching the lead to 20 (60-40) before unloading the bench.
The Tigers next play Saturday at No. 1 Florida.
