CORAL GABLES, Fla. (AP) - Nolan Smith scored 16 of his 18 points in the second half, Seth Curry added 16 and No. 5 Duke extended its Atlantic Coast Conference lead by holding off Miami 81-71 on Sunday night.
Kyle Singler scored 14 and Mason Plumlee 12 for the Blue Devils (23-2, 10-1). Duke's record after 25 games matches its best since the 2005-06 season.
Reggie Johnson scored 16 points on 7-of-9 shooting for Miami (15-10, 4-7), which was bidding for its first four-game ACC winning streak since February 2008. The Hurricanes fell to 1-17 since 2000 against teams ranked No. 5 or higher, the lone win coming against Duke three seasons ago.
No. 10 Connecticut 75, Providence 57
STORRS, Conn. (AP) - Jamal Coombs-McDaniel, who isn't a scorer, had a career-high 25 points and Kemba Walker, the Big East's No. 2 scorer, had 22 as Connecticut beat Providence.
Coombs-McDaniel, whose previous career high was 13 points and who averages 4.5 points per game, finished 10 for 17 from the field and also pulled down a career-high eight rebounds as the Huskies (19-5, 7-5) seemed to straighten out their offense after losing three of four, including two home games.
Walker, who came in averaging 22.9 points, had 14 in the second half. He and Coombs-McDaniel scored all the points in a late 12-0 run that ended any thought of Providence continuing their domination of Connecticut.
Marshon Brooks, the Big East's leading scorer at 24.1 per game, finished with 25 on 7-of-22 shooting including missing seven of eight 3-point attempts.
The Friars (14-11, 3-9), who have lost three of four, had won four of the last five and six of the last nine games against the Huskies.
No. 11 Georgetown 69, Marquette 60
WASHINGTON (AP) - Chris Wright scored 20 points, Austin Freeman added 17 despite limping badly off the court in the first half, and Georgetown survived the run-'em-ragged strategy of Marquette coach Buzz Williams to win its eighth straight game.
The win moved the Hoyas (20-5, 9-4) into sole possession of third place in the Big East and kept alive their longest conference win streak since 2006-07.
Georgetown won despite an off night against Marquette's tough man-to-man defense, shooting 43 percent from the field, including 7 for 27 from 3-point range. But the Hoyas made 16 of 18 free throws and held the Golden Eagles to 40 percent from the field.
Darius Johnson-Odom scored 20 points for Marquette (15-10, 6-6), which dropped back to .500 in the congested heart of the Big East. The Golden Eagles went 1-2 during a three-game road stretch.
No. 14 Purdue 81, Illinois 70
CHAMPAIGN, Ill. (AP) - JaJuan Johnson scored 24 points and E'Twaun Moore added 20 to lead Purdue to a comeback win.
The Illini (16-9, 6-6 Big Ten) led 32-27 at halftime. The Boilermakers (20-5, 9-3) opened the second half with a 10-4 run that gave them a 37-36 lead with just over 15 minutes to play.
It was only Purdue's second lead of the game, but the Boilermakers made it stick. The Illini never led again.
Johnson's jumper with 9:32 left gave Purdue a double-digit lead at 57-46.
After a first half of 28 percent shooting, the Boilermakers scored 54 in the second half.
Illinois was led by Brandon Paul with 23 points. Mike Davis added 16 and D.J. Richardson 13.
No. 15 Arizona 67, Arizona State 52
TEMPE, Ariz. (AP) - Kyle Fogg hit six 3-pointers and matched a career high with 26 points, helping Arizona grind out a win over rival Arizona State.
Arizona (21-4, 10-2 Pac-10) didn't shoot particularly well against Arizona State's zone - 40 percent - and leading scorer Derrick Williams was held to just 11 points. The Wildcats made up for it with a hounding defense and big contributions from Fogg, a 7.9-point scorer on the season, and Jesse Perry, who scored all of his 10 points in the second half.
Arizona State (9-15, 1-11) played gritty defense, blocking a season-high nine shots, but couldn't find many seams in Arizona's man-to-man defense while losing its 10th straight conference game.Jamelle McMillan had 12 points, but the Sun Devils shot 37 percent.
