ARLINGTON, Texas (AP) " Alabama's freshman quarterback Jalen Hurts threw two touchdown passes to ArDarius Stewart and ran for two more scores as the Crimson Tide opened its national college championship defense with a 52-6 victory over Southern California on Saturday.
Alabama, ranked No.1 among this season's contenders, improved to 10-0 in season openers under coach Nick Saban.
It was a mixed day for the highly ranked teams. While Clemson had a hard-fought victory over Auburn, Oklahoma lost at Houston and Louisiana State went down narrowly at Wisconsin.
Alabama trailed until midway through the second quarter when Stewart got in behind the secondary and Hurts found him wide open in the end zone to make it 7-3.
Right after halftime, Hurts found Stewart alone near the Alabama 40 and the receiver sprinted up the right sideline untouched for a 71-yard touchdown and a 24-3 lead.
The season-opening win came at AT&T Stadium " the home of the NFL's Dallas Cowboys " was also where the Crimson Tide started their 2012 and 2015 national championship seasons with victories.
Houston's Brandon Wilson caught a missed field goal attempt by Oklahoma and sprinted the length of the field to help lift the Cougars to a 33-23 win against the Sooners.
Regardless of whether Houston ends up in the Big 12 if the conference expands, the Cougars made an opening statement that could have season-long ramifications.
When Oklahoma kicker Austin Seibert's 54-yard field goal attempt came up just short, Wilson reached up to catch the ball while barely keeping his feet in bounds. He came flying out of the end zone, hit the sideline and hurdled a teammate to score what went into the books as a 100-yard return, making it 26-17 with 8:28 left in the third.
Wisconsin's Rafael Gaglianone kicked a 47-yard field goal with 3:47 left, and the Badgers held off Louisiana State's last-ditch drive and won 16-14.
LSU's frustration was on full display at the end of the game, when offensive lineman Josh Boutte was ejected for a flagrant foul after a blind-side hit on Wisconsin's D'Cota Dixon after the safety sealed the victory with an interception with 57 seconds left.
Clemson's Deshaun Watson passed for 248 yards, including 174 to Mike Williams in his return from an injury, and the Tigers escaped with a 19-13 victory over Auburn.
Clemson struggled to put away Auburn, who produced little offense for much of the game while swapping three quarterbacks in and out. Finally, Watson hit Hunter Renfrow in the back of the end zone on third and goal from the 16 with 9:59 left in the fourth quarter.
Ohio State racked up a team record 776 offensive yards in routing Bowling Green 71-10.
J.T. Barrett threw six touchdown passes and eight players scored touchdowns as the Buckeyes overpowered the Falcons in front of a crowd of 107,193 at sunny Ohio Stadium. The 776 yards topped the 718 yards Ohio State put up against Mount Union in 1930.
Michigan's Wilton Speight threw three touchdown passes in the first half and the Wolverines trounced Hawaii 63-3 in its most lopsided victory since 1975.
