Baylor, which beat Texas Tech to improve to 9-0 on Saturday, sits a microscopic .0013 behind the Buckeyes in the BCS average. Last week, the gap between the teams was .0308.
No. 2 Florida State also closed the gap on No. 1 Alabama by about 25 percent, but both teams are comfortably positioned ahead of the other contenders in the two spots that earn a berth in the VIZIO BCS National Championship.
Alabama slogged through a 20-7 win at Mississippi State, while Florida State crushed Syracuse 59-3.
Florida State and Ohio State are both 10-0, but the Seminoles lead the Buckeyes by .0792, leaving little doubt that if the two front-runners win their remaining games, they will play for the national title.
Alabama and Florida State are tied for first in the computer ratings, while Baylor and Auburn are tied for third. Ohio State is fifth.
After Baylor in the standings, the next four teams also all moved up one spot after Stanford lost its second game of the year and dropped five spots to No. 9.
Stanford needed a boost from the computers to remain in the top 10 after losing to USC on Saturday night. The Cardinal were ranked 11th in the Harris Poll and 12th in the USA Today poll, but they had the eighth-best computer ranking.
No. 23 USC moved into the standings for the first time this year, a feat that seemed unlikely when coach Lane Kiffin was fired in September. Interim coach Ed Orgeron has gone 5-1 in charge of the Trojans since.
Oklahoma State moved up two spots to No. 10 ahead of this Saturday's showdown with Baylor.
No. 15 Fresno State, which did not play last week, remains the top team from outside the BCS automatic-qualifying conferences and would qualify for a BCS bowl if the season ended today.
The 9-0 Bulldogs would earn a spot if they finish in the top 16 and stay ahead of the champion from the American Athletic Conference. The American's UCF fell one spot to No. 18 after another last-minute win, while Louisville also dropped a spot to No. 21.
No. 16 Northern Illinois cut the gap on Fresno State by about 50 percent in the fight to bust into the BCS with an impressive beatdown of 9-2 Ball State on Wednesday.
