BATON ROUGE, Louisiana (Ticker) -- It did not take long for eighth-ranked Louisiana State to show it was not looking ahead.
In a dominating performance, Matt Mauck completed all 14 of his first-half passes and threw four touchdowns as the Tigers rolled to a 49-10 rout of Louisiana Tech.
Mauck had 277 yards in the first half as the Tigers (8-1) took a 49-3 lead. It took less than four minutes for them to get rolling as Mauck hooked up with Michael Clayton on a 34-yard TD strike.
After Justin Vincent's seven-yard TD run made it 14-0, Mauck threw an eight-yard TD to Skyler Green and two scores to Devery Henderson.
Facing Louisiana Tech for the first time since 1941, the Tigers recorded 653 yards of total offense and shut down Luke McCown, who was just 11-of-28 for 152 yards.
Mauck finished the game by completing 18-of-20 passes for 311 yards. He posted his second 300-yard game of the season and helped LSU to its best nine-game start since 1973.
Mauck also helped LSU avoid a letdown in its final non-conference game. The Tigers are tied for second in the Southeastern Conference West Division, one game behind surprising Mississippi.
The Tigers posted their third straight win since getting upset at home by Florida three weeks ago. During the winning streak they have scored 89 points in the first half alone.
"These last three games, which we've come out and played well, we've really gotten off to a good start," Mauck said. "My teammates did such a good job. That really made it almost kind of easy for me. I didn't have to do a whole lot. They did most of the work."
"Obviously, that's a very pleasing win for us," LSU coach Nick Saban added. "I was very pleased with the way we played in the first half. We played pretty well on both sides of the ball."
It was the most yards for the Tigers gained against a Division I-A opponent since they had 664 vs. Rice on September 19, 1987. It also marked LSU's most productive half since it scored 56 points in the second half of a 66-0 victory at Tulane on November 22, 1958.
What LSU showed on defense oprompted McCown and his coach Jack Bicknell to suggest the Tigers might be better than second-ranked Miami, which suffered a 31-7 loss to Virginia Tech and opened its season with a 48-9 win over the Bulldogs.
"They are a great football team and they have a shot at winning the national championship," McCown said. "Their defense is obviously as good as Miami's or better."
"That was just a fantastic football team we played and if they are not the best team in the country, I'd be shocked," Bicknell added. "I just feel like the speed out there was unbelievable, big players. We played Miami and I promise you I feel like they are better than Miami."
Bicknell's pass defense entered last among the 117 teams in Division I-A and Mauck took full advantage. Clayton recorded his 17th career TD to move into tie for third place on the school's all-time list with Josh Reed and Ken Kavanaugh.
Vincent doubled the lead and defensive tackle Kyle Williams intercepted McCown at the Louisiana Tech 19, setting up Green's eight-yard score with 3:19 remaining.
Just 21 seconds later, safety Jack Hunt stepped in front of a pass and returned it 29 yards for a 28-0 lead.
In the second quarter, Mauck hit Henderson for TDs of 46 and 50 yards to make it 42-3 with 9:28 remaining. On the next scoring drive, Mauck did not throw a pass as Alley Broussard capped the scoring for the Tigers with a 22-yard run.
"It's correcting our mistakes," Clayton said of LSU's winning streak. "Early in the season we saw a lot of things. It wasn't really mistakes that other teams were making. It was mistakes that we were making that we could prevent. We just worked on those things and now it's starting to come along."
Mauck, who threw four TDs in a game for the second time this season, gave way to backup Marcus Randall in the second half. Randall was 6-of-9 for 54 yards, but did not direct any scoring drives.
