DURHAM, N.C. (AP) — Quinn Cook scored 22 points and No. 4 Duke beat No. 15 North Carolina 92-90 in overtime on Wednesday night.

In a thriller befitting college basketball's fiercest rivalry, the Blue Devils (23-3, 10-3 Atlantic Coast Conference) let an early 13-point lead slip away and trailed by 10 with less than four minutes left in regulation before rallying. They sent it into OT and won their ninth in 12 in the series.

Tyus Jones had 22 points, Justise Winslow added 16 points and Jahlil Okafor had 12 points and 13 rebounds for Duke.

Kennedy Meeks and Brice Johnson each scored 18 points to lead North Carolina (18-8, 8-5). Nate Britt pulled the Tar Heels within two with one free throw with 3.5 seconds left. He missed the second, Marcus Paige raced in and got his hands on the rebound — but Winslow grabbed it as the buzzer sounded.

No. 5 Wisconsin 55, Penn State 47

STATE COLLEGE, Pa. (AP) — Sam Dekker scored 22 points and Frank Kaminsky added 16 as No. 5 Wisconsin overcame a late Penn State surge.

Dekker and Penn State's D.J. Newbill waged an entertaining scoring battle. Newbill scored 29 points, but the next-highest scorer for Penn State (15-12, 3-11) was Brandon Taylor with seven.

The Badgers (24-2, 12-1), despite shooting 39 percent, were aided by Nigel Hayes' 13 rebounds and nine points.

Wisconsin's 24th victory marked the school's best start in program history.

No. 11 Northern Iowa 59, Loyola 39

CHICAGO (AP) — Seth Tuttle and Nate Buss each scored 10 points as Northern Iowa won its 14th straight.

The Panthers (25-2, 14-1 Missouri Valley Conference) never trailed and moved within one win of matching the 2009-10 team's school record streak.

They also tied a season low for points allowed while holding Loyola (16-11, 6-9) to its lowest scoring total, and this game was every bit as lopsided as the numbers indicated.

Northern Iowa led by 12 at halftime and broke it open after the Ramblers trimmed it to nine early in the second period.

Syracuse 69, No. 12 Louisville 59

SYRACUSE, N.Y. (AP) — Rakeem Christmas rebounded from his worst game of the season, scoring 29 points and blocking four shots.

It was the first game between the teams as members of the Atlantic Coast Conference.

Syracuse (17-9, 8-5 ACC) was coming off an 80-72 home loss to fourth-ranked Duke in which Christmas was outplayed by freshman Jahlil Okafor.

Louisville (20-6, 8-5) was out to bounce back from Saturday's home loss to North Carolina State, but was without senior guard Chris Jones, who was suspended for violating team rules and did not make the trip. Freshman Quentin Snider made his first start in place of Jones, the team's assist leader (3.7 per game) and third-leading scorer (13.6 points).

The Cardinals have lost three of four and two straight after leading at the half.

No. 14 Iowa State 70, No. 22 Oklahoma State 65

STILLWATER, Okla. (AP) — Jameel McKay had career highs of 17 points and 14 rebounds for Iowa State.

McKay, a 6-foot-9 forward, created problems on both ends with his leaping ability. He made 13 of 18 free throws, blocked four shots and had nine offensive rebounds.

Dustin Hogue scored 14 points, Monte Morris had 11 points and Georges Niang scored all nine of his points in the second half for the Cyclones (19-6, 9-4 Big 12). Iowa State outrebounded Oklahoma State 44-28 and had 18 offensive boards to snap a four-game road losing streak.

Le'Bryan Nash and Phil Forte each scored 13 points, but they combined to make just 7 of 24 shots for the Cowboys (17-9, 7-7), who lost their second straight after three consecutive wins over ranked teams.

No. 18 Arkansas 84, Missouri 69

FAYETTEVILLE, Ark. (AP) — Michael Qualls had 21 points and Arkansas beat Missouri for its fifth straight victory and eighth in nine games.

Bobby Portis added 16 points on 8-of-12 shooting to help the Razorbacks (21-5, 10-3 Southeastern Conference) continue their best start in conference play since the 1997-98 season. Arkansas' only loss since Jan. 17 is a 57-56 setback at Florida.

Qualls scored in double figures for the third straight game. The junior is 17 of 34 from the field in his last three games after going 14 of 59 in his previous five.

Missouri (7-19, 1-12) has lost 12 straight games for the first time since the 1966-67 season.

Jonathan Williams and Tramaine Isabell led the Tigers with 13 points each.
