Penn State has climbed to No. 2 in The Associated Press College football poll behind unanimous No. 1 Alabama after a wild weekend of upsets gave the Top 25 a major makeover.

A season-high seven ranked teams, including four in the top 10, lost to unranked teams on Friday and Saturday. Defending national champion Clemson and defending Pac-12 champion Washington were the highest ranked teams to lose.

Penn State, which was idle, took advantage. The Nittany Lions moved up a spot to No. 2, 15 points ahead of No. 3 Georgia. Penn State has its best ranking since Oct. 31, 1999, when the Nittany Lions were No. 2. Alabama, which has been No. 1 since the preseason, received all 61 first-place votes for the first time this year.

TCU is No. 4, Wisconsin is No. 5 and Big Ten rival Ohio State is sixth.

Clemson dropped five spots to seventh. Miami, Oklahoma and Oklahoma State round out the top 10.
