COLLEGE STATION, Texas — No. 24 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 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 left was placed at the 1 but was reviewed and reversed."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." A&M had a last chance, but Manziel, the Heisman Trophy winner, was sacked by defensive end Dee Ford on fourth down.
