Patrick Mahomes threw for 370 yards and four touchdowns for Texas Tech, but was under heavy pressure all night and was sacked six times and scrambled away from probably 10 more. Jakeem Grant set a Texas Tech bowl record with three receiving touchdowns.

It was the 10th 100-yard rushing game and fourth of 200 this season for Fournette, who extended his LSU single-season rushing record with 1,953 yards. LSU outrushed Texas Tech 384-29 as the Tigers took advantage of a run defense that is one of the worst in the nation.

Brandon Harris threw for 254 yards with a touchdown and an interception and ran for another score for LSU.

Dakota Allen intercepted a pass by Harris early in the third quarter and Texas Tech made it 21-20 on a 31-yard touchdown reception by Reginald Davis three plays later.

Fournette was stopped for no gain on one carry on LSU's next drive and managed just two yards on the next one. But Texas Tech couldn't corral him on his next run and he broke free for a 43-yard run to give him the LSU record for rushing touchdowns in a season with 20 and push the lead to 28-20.

The Red Raiders were driving on their next possession when Rickey Jefferson intercepted a pass that was deflected on the LSU 1-yard line.

Fournette pushed LSU's lead to 35-20 on a 4-yard touchdown run after the interception. Trey Quinn had a 46-yard reception to set up that score.

Harris made it 42-20 when he ran 26 yards for a touchdown with nine seconds left in the third quarter.

Grant had a 4-yard reception for Texas Tech that made it 42-27 early in the fourth quarter.

Fournette sailed into the end zone Superman style on a 2-yard run with about eight minutes left.

He got going early when he shed one defender and hurdled another one on a 35-yard run on his second carry. He finished that drive with a 2-yard touchdown run to give LSU a 7-0 lead. He celebrated the score with the ''running off on the da plug twice'' dance from a song by rapper Plies. The dance basically looks like a spirited run in place, with arms pumping and a bit of a shuffle.

Texas Tech closed the gap when Grant got in front of the secondary and grabbed a 46-yard touchdown pass, but the 2-point conversion failed to make it 7-6.

D.J. Chark ran 79 yards for a touchdown on LSU's next play to make it 14-6. One Texas Tech defender caught up to him at about the 10-yard line but Chark simply dragged him into the end zone for the longest run in Texas Bowl history.

Fournette's fast start and the run by Chark left LSU with 143 yards rushing in the first quarter to minus-15 yards by the Red Raiders.

Fournette pushed LSU's lead to 21-6 when he took a screen pass 44 yards for a touchdown with about 6 1/2 minutes left in the second quarter.

The Red Raiders got within eight points when Grant, who finished with 125 yards receiving, grabbed a 3-yard pass from Mahomes about three minutes later.
