COLLEGE STATION, Texas — Auburn didn’t win a single Southeastern Conference game last season.
So no one could blame running back Tre Mason for shedding a few tears as the final seconds ticked off in the 24th-ranked Tigers’ 45-41 upset of No. 7 Texas A&M on Saturday.
‘‘Those were tears of happiness,’’ he said. ‘‘We did something a lot of people didn’t think we could do.’’
Nick Marshall accounted for four scores and Auburn battered Johnny Manziel in the victory. Last season the Aggies beat Auburn, 63-21.
Mason’s 5-yard score with less than two minutes to play was first placed at the 1, but it was reviewed and ruled a touchdown.
‘‘Our plan was to be in the game at halftime and wear them down in the second half,’’ Auburn coach Gus Malzahn said. ‘‘I think for the most part it worked.’’
Texas A&M (5-2, 2-2) had a last chance, but Manziel, the reigning Heisman Trophy winner, was sacked by Dee Ford on fourth down.
‘‘We didn’t make enough plays at the end of the day,’’ Texas A&M coach Kevin Sumlin said. ‘‘We had our opportunities — couldn’t make a play.’’
Manziel threw for 454 yards and four touchdowns and ran for a fifth score, but was intercepted twice. He missed a series in the fourth quarter with an injury to his right shoulder. He returned but was constantly moving his right arm. Sumlin didn’t provide any details on the injury after the game, but said Manziel told him he was ‘‘ready to go.’’
Marshall threw for 236 yards and two touchdowns and ran for 100 yards and two more scores for Auburn (6-1, 3-1).
Texas A&M’s Mike Evans had a school-record 287 yards receiving with four touchdowns to become the first player in school history to have two 200-yard receiving games in a career. He scored on receptions of 26, 64, 42, and 33 yards.
Manziel was injured when he was tackled on an 8-yard run early in the fourth quarter.
He got up after the tackle and then went to the ground before he reached the A&M sideline. A&M officials looked at him for a couple of minutes on the turf before he got up and walked off on his own power.
He was replaced by Matt Joeckel, who threw an incomplete pass on third down and A&M settled for a 20-yard field goal to push the lead to 34-24.
Marshall cut A&M’s lead to 3 when he ran 13 yards for a touchdown with about 12 minutes left.
Joeckel remained in for A&M’s next possession and the Aggies had to punt.
Cameron Artis-Payne put Auburn ahead, 38-34, with a 2-yard TD run with about nine minutes remaining. Mason slashed through the line and ran 53 yards to set up the score.
Manziel returned and orchestrated a 75-yard drive capped by his 1-yard TD run to give A&M a 41-38 lead with about five minutes left.
It was the second straight game that Manziel suffered an injury. In a win over Ole Miss last Saturday, Manziel appeared to injure his left knee in the first quarter. He returned after missing only a handful of plays.
