Baylor took its first loss of the season on Saturday in a 71-58 defeat on the road to Kansas that left only one undefeated team -- No. 1 Gonzaga -- left standing in college basketball. So on Monday it prompted a substantial shakeup inside the top five of the AP Top 25, with the Bears falling out of the No. 2 spot for the first time all season.

Slotting in at No. 2 in their place is Michigan, which dismantled Indiana on Saturday to claim its seventh consecutive win. The Wolverines (18-1, 13-1 Big Ten) missed nearly a month of action in January and February on a COVID pause, but have won five straight games since their return. They can clinch the Big Ten regular-season title Tuesday against Illinois, which stands in second in the race. And they are already well-positioned to secure a No. 1 seed in Jerry Palm's latest Bracketology.

The No. 2 ranking for Michigan is its highest under coach Juwan Howard and the highest as a program since John Beilein got them to the No. 2 spot in 2019, per data from college basketball reference.

As for Gonzaga, it closed its regular season Saturday with an 86-69 win over Loyola Marymount to complete a wire-to-wire run -- from preseason to the end of its regular season -- as the No. 1 team in the sport. The Bulldogs garnered 59 first-place votes, drawing some lingering votes away from Baylor backers after it lost over the weekend. Baylor dropped to No. 3 and did not receive any first-place votes for the first time all season.
