Auburn came in a week removed from beating then-No. 1 Georgia on the road, and it never got its run game started. LSU blitzed and spied Byrum Brown early, according to the AP, after Brown ran for 115 yards against Georgia. On Saturday he carried 19 times for 21 yards, though he did score on a 1-yard run, and he was sacked six times. Brown completed 15 of 24 passes for 160 yards. Keshaun Singleton caught four passes for 64 yards. Tristan Ti'a scored Auburn's other touchdown on a 7-yard run with 24 seconds left.
LSU outgained Auburn 552 yards to 271, picked up 29 first downs and converted 3 of 4 fourth downs. Linebacker Davhon Keys had seven tackles and a sack, and PJ Woodland made nine tackles. The AP said it was the first time Auburn had been blown out in Alex Golesh's first season; its earlier losses to Florida and Tennessee were competitive.
LSU (6-2) is off next week and hosts No. 13 Alabama on Nov. 7. Auburn (4-3, 2-3 SEC) plays at No. 7 Ole Miss next Saturday, its fourth straight ranked opponent.
