There's a big shakeup in the AP Top 25 rankings for the second successive week.

Last week, seven of the top 10 teams suffered losses, leading to undefeated Gonzaga jumping from No. 5 to the No. 1 spot.

On Saturday, a record was tied when six top-10 teams went down in one day.

Below is the latest AP top 25 with first place votes in parentheses.

The movement wasn't unexpected after Saturday's results.

It wasn't a good weekend for top-ranked home teams in the Big 12. Unranked Iowa State ended No. 3 Kansas' 54-game home winning streak in Lawrence. Unranked Kansas State dropped then-No. 2 Baylor in Waco. And unranked Oklahoma State extended its winning streak to five games with an upset over then-No. 7 West Virginia in Morgantown.

Bob Huggins wasn't pleased!

After all the madness, the two top Big 12 teams chasing Kansas had a chance to close the gap, yet Baylor and West Virginia missed big opportunities to make up ground in league play. Despite it all, the Big 12 race is still wide open. Baylor is only a game back and there are still eight games left in conference play. And while the top of the Big 12 took a hit, the upsets could be a boost to the conference on the whole as OSU, Iowa State, and Kansas State notched signature wins that will significantly boost its tournament resume.

In the SEC, Kentucky fell from No. 8 to No. 15 after its worst loss of the season: a 22-point rout at the hands of Florida. That leaves South Carolina at the top of the league standings, and Florida ahead of the Wildcats with the tiebreaker in hand. John Calipari's team is young, and right now they are playing young. The Wildcats are trending downward with three losses in four games.
