LSU moved up three spots to No. 15 in the Armway coaches poll and two spots to No. 15 in the Associated Press top 25, both of which were released Sunday.

The Tigers are 4-1 after beating New Mexico State 63-7 behind a breakout performance from true freshman quarterback Brandon Harris. LSU, 0-1 in Southeastern Conference play, travels to No. 5 Auburn (4-0, 1-0 SEC) next Saturday.

LSU fell 10 spots to No. 18 in the coaches poll last week after a loss to Mississippi State, the biggest tumble in those rankings since 2008. The nine-spot fall last week was the biggest in the AP poll since 2004

Alabama replaced Florida State as the coaches poll’s No. 1 team.

A 43-point favorite, the Tigers whipped the Aggies (2-3) on Saturday night in an expected blowout, but the result was overshadowed by the quarterback competition between Harris and Anthony Jennings.

Harris led LSU on touchdowns in his seven drives, while a Jennings-led offense sputtered in the first seven drives of the game. Jennings threw two interceptions and lost a fumble. He did not re-enter the game after Harris took over with less than 10 minutes left in the second quarter.

Coach Les Miles afterward declined to announce a starter for the game at Auburn.
