Alabama secured its hold at the top of the BCS standings a day after winning its biggest road test of the season.
The Crimson Tide, No. 1 in both the USA Today and Harris polls, rallied for a 21-17 win at LSU on Saturday and were rewarded by the computer average that makes up one-third of the BCS standings.
Last week, Alabama was rated No. 1 by only one of the six computer formulas. After beating LSU, four of the computers rate Bama No. 1. The Tide are 2nd and 3rd in the other computers; Notre Dame is No. 1 in both of those. The average discounts the six computers' highest and lowest rating.
Alabama's advantage over Kansas State in the full BCS average increased from .0359 to .0639.
The Ducks also nearly halved the gap between them and Kansas State, shrinking the difference in average from .0264 to .0152.
Of the four, only Alabama and Oregon would have to play in their conference championships before bowl season begins.
LSU fell two spots from fifth to seventh after its loss.
