DURHAM, N.C. — R.J. Barrett scored 30 points, Zion Williamson had 27 and No. 1 Duke beat No. 4 Virginia 72-70 on Saturday night to give the Cavaliers their first loss of the season.

The Blue Devils (15-2, 4-1 Atlantic Coast Conference) bounced back from an overtime loss to Syracuse that could cost them their top ranking. They avoided their first two-game losing streak at home since 2016 and proved they can win without injured point guard Tre Jones.

DeAndre Hunter scored 18 points, and Ty Jerome and Kyle Guy had 14 apiece for the Cavaliers (16-1, 4-1), who entered as the nation’s last unbeaten team after No. 2 Michigan was upset at Wisconsin earlier in the day.

The fourth matchup of top-ranked teams in the sport’s history – Virginia entered at No. 1 in the coaches’ poll – was a tournament-caliber game throughout. There were 14 ties and 15 lead changes, and it was a one-possession game for a 14½-minute stretch of the second half.

After the Cavaliers missed 11 of 12 shots during a late nine-minute stretch, they pulled within 69-66 on Guy’s 3-pointer with 23 seconds left. Barrett hit two free throws with 20.9 seconds to play, and Virginia let too much time elapse before Braxton Key was fouled with 8.9 seconds remaining and hit both shots to make it 71-68.

Cameron Reddish hit a free throw to make it a four-point game before Hunter hit a jumper before the buzzer for Virginia.

WISCONSIN 64, (2) MICHIGAN 54: Ethan Happ scored 26 points and had 10 rebounds as Wisconsin (12-6, 4-3 Big Ten) handed Michigan (17-1, 6-1) its first loss of the season, breaking away in the final minute at Madison, Wisconsin.

Fans rushed the floor after the Badgers finished off the upset.

(3) TENNESSEE 71, ALABAMA 68: Grant Williams scored 21 points and Tennessee (16-1, 5-0 SEC) rallied past Alabama (11-6, 2-3) at Knoxville, Tennessee, for its 12th straight win and a chance to climb atop the AP Top 25.

After No. 1 Duke lost to Syracuse on Monday and No. 2 Michigan fell at Wisconsin on Saturday, the Volunteers could lead the poll Monday for the first time since 2008.

WEST VIRGINIA 65, (7) KANSAS 64: Jermaine Haley hurried up the court and hit a layup with 8.5 seconds left, completing a late rally that lifted West Virginia (9-9, 1-5 Big 12) over Kansas (15-3, 4-2) at Morgantown, West Virginia.

West Virginia scored the final seven points to break a five-game losing streak.

After Texas Tech scored 11 straight to get within a basket, Butler hit a 3-pointer with 4½ minutes left before Jarrett Culver of Texas Tech had a short shot roll off the rim. That led to Butler driving for a layup and making the free throw after getting fouled to stretch the lead back to 61-53.

(9) VIRGINIA TECH 87, WAKE FOREST 71: Nickeil Alexander-Walker scored 24 points and Virginia Tech (15-2, 4-1 Atlantic Coast) used a 14-4 first-half run to pull away from Wake Forest (8-9, 1-4) at Blacksburg, Virginia.

Ty Outlaw added 14 points and Ahmed Hill scored 12 for the Hokies. Outlaw, Hill and Justin Robinson each made a 3-pointer during the burst, which turned a 17-17 game into a 31-21 lead with four minutes left in the half. The Demon Deacons didn’t get closer than eight the rest of the way.

(12) KENTUCKY 82, (14) AUBURN 80: Tyler Herro made two free throws with 24 seconds left and Immanuel Quickley added another to help visiting Kentucky (14-3, 4-1 SEC) survive a big rally by Auburn (13-4, 2-2).

The Wildcats rebounded after losing a 17-point second-half lead to finish off a showdown between two of the league’s top teams.

(13) NORTH CAROLINA 85, MIAMI 76: Cameron Johnson scored 22 points, including 3-pointers on consecutive possessions in the closing minutes, and North Carolina (14-4, 4-1 Atlantic Coast) won a seesaw game against Miami (9-8, 1-4) at Coral Gables, Florida.

The Tar Heels shot 55 percent, including 9 of 20 from beyond the arc, and showed why they’re ranked second in the nation in rebounds by grabbing a 38-23 advantage on the boards.

(17) NORTH CAROLINA STATE 77, NOTRE DAME 73: C.J. Bryce scored 23 points and North Carolina State (15-3, 3-2 Atlantic Coast) withstood several second-half challenges from Notre Dame (11-7, 1-4) at South Bend, Indiana.

Eastern finished with 10 points and 10 rebounds while locking down Indiana freshman guard Romeo Langford. Langford had four points on 2-of-10 shooting and committed three turnovers. He missed all four of his free throws and was dogged with “overrated” chants most of the game.
