NEW YORK (AP/WVLT) -- Southern California has jumped two spots to No. 1 in The Associated Press Top 25 college football poll, rewarded by voters for opening the season with a dominant performance on the road against a BCS conference opponent.

Tennessee fell out of the AP Top 25, receiving 30 votes, while UCLA moved into the No. 23 spot after beating the Vols.

Georgia and Ohio State, the preseason Nos. 1 and 2, respectively, started their seasons with glorified scrimmages at home against FCS (formerly I-AA) teams.

USC's 52-7 victory Saturday at Virginia helped the Trojans vault past the Bulldogs and Buckeyes from No. 3 in the preseason. Georgia fell to No. 2 and Ohio State to No. 3.

The voting was close. USC received 21 first-place votes and 1,539 points from the 65-member media panel. Georgia had 20 first-place votes and 1,506 points. Ohio State got 15 first-place votes and 1,497 points.
