Undefeated Michigan continues its ascent up the men’s college basketball rankings ladder, thanks in part to the shake-up due to Arizona State’s upset win over top-ranked Kansas during the weekend.

The Wolverines (12-0) moved to No. 2 from No. 4 in the Associated Press Top 25, up two  spots after thrashing Air Force 71-50 on Saturday at Crisler Center.

Michigan State (10-2) also jumped to No. 8 from No. 10 after demolishing Oakland 99-69 Friday at Breslin Center. The Spartans scored 47 fast-break points in the romp in which junior guard Cassius Winston posted a season-high 26 points.

Duke is back atop the AP rankings.

The Blue Devils received 35 of 64 first-place votes in Monday’s poll after previous No. 1 Kansas lost at Arizona State.

Michigan received nine first-place votes, No. 3 Tennessee 12, with No. 4 Virginia and No. 5 Kansas getting four each.

No. 6 Nevada, Gonzaga, Michigan State, Florida State and Virginia Tech rounded out the top 10.

The Blue Devils moved to No. 1 in the first regular-season poll after rolling over Kentucky, but dropped back after losing to Gonzaga in the Maui Invitational title game.

Duke blew out Princeton, then knocked off previously-unbeaten No. 12 Texas Tech at Madison Square Garden on Thursday.
