Duke was the ACC’s preseason favorite and North Carolina the defending national champion. The conference leader and highest-ranked team as of Monday: Virginia.

Picked to finish sixth in the ACC preseason poll, the Cavaliers have been the conference’s most consistent team this season behind their still-stifling defense.

Virginia (16-1, 5-0 ACC) moved up a spot to No. 2 and received a first-place vote in the AP Top 25 released Monday, its highest ranking since reaching No. 2 in the 2014-15 season.

The Cavaliers, No. 1 in KenPom.com’s defensive-efficiency rankings, beat Syracuse and North Carolina State last week.

Villanova remained at the top spot for the second straight week, receiving 63 of 65 first-place votes from a media panel. The Wildcats (16-1, 4-1 Big East) moved atop the poll for the second time this season after Michigan State’s loss to Ohio State on Jan. 7 and stayed there after wins over No. 10 Xavier and St. John’s.

Purdue had the other No. 1 vote and moved up two spots to No. 3, its highest ranking since reaching No. 3 in 2009-10 after extending its winning streak to 13 games with victories over Michigan and Minnesota. Matt Painter’s Boilermakers (17-2, 6-0 Big Ten) are off to their best start since 1987-88 and best in the Big Ten since winning the first eight games of 1989-90.

Stanford’s Davis wins honor: Daejon Davis, who led Stanford to its first conference road sweep in eight years, was named Pac-12 Player of the Week. He averaged 15.5 points, 6.0 rebounds and 4.5 assists to give the Cardinal the honor for the first time since 2015.

Texas Tech fined: The Big 12 has fined Texas Tech $25,000 and reprimanded West Virginia forward Wes Harris for hitting a Tech fan who joined thousands of others in storming the court during a postgame celebration.

Big 12 Commissioner Bob Bowlsby said Texas Tech did not ensure the safety and security of West Virginia players.

Louisville women No. 2: Undefeated Louisville moved up to No. 2 in the AP women’s poll, the highest ranking in school history. The Cardinals advanced one spot after routing then-No. 2 Notre Dame 100-67 Thursday.

Only UConn is above Louisville, remaining a unanimous top choice by the 32-member national media panel. Mississippi State, Baylor and Notre Dame follow the Cardinals, who were second on 30 of the 32 ballots. Tennessee, Oregon, Ohio State, Texas and South Carolina round out the first 10 teams in the poll.

Cal moved up three spots to No. 21. Stanford remained unranked.
