NORMAN, Okla.  — Baker Mayfield passed for 331 yards and four touchdowns, and No. 2 Oklahoma followed its impressive victory at Ohio State with a 56-14 win over Tulane on Saturday.

Oklahoma receiver CeeDee Lamb caught four passes for 131 yards and two touchdowns before he was ejected for targeting on a block in the second quarter. Marquise Brown had career highs of six catches for 155 yards, including an 87-yard touchdown grab in the fourth quarter for the Sooners (3-0).

The Sooners and Green Wave were tied at 14 in the second quarter before Oklahoma's Parnell Motley returned an interception 77 yards for a touchdown to turn the momentum for good. Oklahoma extended its nation-leading win streak to 13 games.

Tulane (1-2) scored on its first two drives and never scored again. Dontrell Hilliard ran for 104 yards and a touchdown to surpass 2,000 yards rushing in his career for the Green Wave.

THE TAKEAWAY

TULANE: The Green Wave were solid in a 23-21 loss to Navy last Saturday, and were good again for much of the first half against Oklahoma. Tulane controlled the clock before the break, holding the ball for more than 20 minutes and keeping Mayfield on the sideline. Quarterback Johnathan Brantley had great moments, but the interception changed the game.

OKLAHOMA: Oklahoma's defense locked in after the first quarter. Tulane gained 157 yards in the first quarter and 134 the rest of the game. The Sooners outscored the Green Wave 35-0 after the targeting call.

UP NEXT
TULANE: The Green Wave host Army on Saturday. The Black Knights lost to Ohio State 38-7 on Saturday following wins over Fordham and Buffalo.

OKLAHOMA: The Sooners open conference play at Baylor on Saturday. Baylor fell to 0-3 after a 34-20 loss to Duke on Saturday. Baylor defeated Oklahoma in 2011, 2013 and 2014, so the Bears should have the Sooners' attention, regardless of record.

Texas A&M 45,

Louisiana-Lafayette 21

Texas A&M needed a second-half comeback to defeat Louisiana-Lafayette 45-21 on Saturday at Kyle Field.

The Ragin' Cajuns (1-2) led 21-14 at halftime before the Aggies scored 31 consecutive points en route to the victory, one preserving embattled coach Kevin Sumlin's job for at least another week.

"We just talked about that in the locker room, that we were like two different teams," Sumlin said of the Aggies' Jekyll and Hyde showing. "We're a work in progress."

After much of the first half went wrong for A&M, the third quarter went entirely right, as the Aggies (2-1) scored 17 points in that span to grab the lead for good.

"In the second half they made some adjustments, they put a lot of people in the box to stop the run," Cajuns coach Mark Hudspeth said. "They were determined to make us throw the football to win the game, and we just didn't have that offensive rhythm in the second half that we had in the first half."

Freshman Aggies quarterback Kellen Mond, in beginning to live up to his preseason hype as a five-star prospect, collected a five-yard touchdown run and threw a 12-yard touchdown pass to fellow freshman Camron Buckley in the decisive third quarter.

"He's gotten better," Sumlin said of Mond. "He's more comfortable, and he's more assertive."

Sumlin is on the hot seat after the Aggies have lost six consecutive games to Power Five opponents, dating to last season and including A&M blowing a 34-point lead against UCLA in this year's season opener.

The Aggies have responded with two consecutive victories, but also needed to break open a 14-14 tie against Nicholls State last week before prevailing 24-14.

"We still have a lot of work to do this week, we can't be content with what happened today," said A&M safety Armani Watts, who collected two of the Aggies' three interceptions. "We just played with more emotion in the second half. You can't play this game without emotion. We stuck with it and knew our offense would come through."

Southern 17

Dalton Sturm threw for four touchdowns and ran for a fifth, all in the first half, as UT San Antonio dismantled Southern 51-17 in a nonconference game Saturday night.

Tyrell Clay punched in from the 2 to give UT San Antonio a 21-0 lead after one quarter.

Sturm sandwiched a pair of touchdown passes to Shaq Williams, from 17- and 14-yards out, around his own 8-yard run for a score in the second quarter, then capped his first half with an 11-yard pass to Josh Stewart for a 48-0 lead.

McNeese 34,

Alcorn State 27

James Tabary hit Kent Shelby on a 33-yard scoring strike with 26 seconds remaining in the game to give McNeese a 34-27 victory over Alcorn State on Saturday night.

McNeese (2-1), which is 12-0 against SWAC teams, led most of the way but Lenorris Footman hit De'Lance Turner in stride for a 70-yard touchdown to tie at 27-27 at the start of the final quarter.

Tabary was intercepted on the next series and McNeese's Calum Foster returned the favor, picking off Footman, as the Braves were driving. Neither team could mount another drive until Tabary took the Cowboys 62 yards in four plays to seal the win.

Tabary threw for 310 yards with four touchdowns as McNeese scored twice in the final quarter. Lawayne Ross hauled in five passes for 72 yards and Justin Pratt rushed for 114 yards on 13 carries.

Smith was 22 of 39 for 306 yards passing and threw an 87-yard touchdown pass to Rhashid Bonnette in the second quarter.

Mike White threw for 226 yards and scored on a 4-yard touchdown run in the first quarter to lead Western Kentucky (1-2, 0-1).

Southern Miss 28,

Louisiana-Monroe 17
Ito Smith ran for a career-high 219 yards and Kwadra Griggs threw for three touchdowns to lead Southern Mississippi to a 28-17 win over Louisiana Monroe on Saturday night.

Smith, who had 27 carries, had a 27-yard touchdown run early in the second quarter to put the Golden Eagles on top 14-7. He also surpassed 5,000 all-purpose yards, second in school history.

Griggs, in his second start, connected with Korey Robertson for a 15-yard touchdown to open the second. The duo hooked up again for a 20-yard score late in the second quarter to make it 21-10 at the half.

After Caleb Evans broke loose for a 67-yard score for the Warhawks (0-2) to cut the deficit to 21-17, Griggs capped a 9-play, 79-yard drive on the next possession with a 42-yard scoring pass to Allenzae Staggers.

From there the defense took over, limiting Louisiana Monroe to 3 of 16 on third-down conversions and holding Evans and Garrett Smith to 11 of 27 passing for 112 yards.

Central Arkansas 38,

Southeastern Louisiana 6

Three minutes later, Lorenzo Nunez fumbled while being sacked by Chris Terrell and the Bears' Raphael Garner scooped up the ball and went 38 yards to score to make it 35-3 entering the final period.

Crossley scored on runs of 2 and 18 yards and finished with 81 yards on 10 carries. Carlos Blackman got the Bears' first points with a 7-yard run two minutes into the game.

The Bears (2-1, 1-0) outgained the Lions (0-3, 0-1) 473-279 with the difference coming in the air.

Three Lions quarterbacks combined to throw just 13 passes, completing six for 84 yards.

Northwestern State 35,

Lamar 28

Jared West ran for 75 yards and three touchdowns and Northwestern State held on to beat Lamar 35-28 on Saturday night in a Southland Conference opener.

Darrel Colbert Jr. scored on a 9-yard run to pull Lamar to 35-28 with 8:51 to play. Northwestern State (1-2, 1-0) ate up about five minutes of the clock on its next series, but offside and holding penalties stalled the drive.

Lamar (1-2, 0-1) drove to the Northwestern State 44, but Isaac Warren intercepted Colbert's pass on a third-and-16 with about a minute left and Northwestern State ran out the clock.

West scored his touchdowns from inside the 3-yard line.  J.D. Almond threw a 25-yard touchdown to Jaylen Watson in the second quarter. Almond's 7-yard run stretched the Demons' lead to 35-21 early in the fourth quarter.
