Nate Laszewski swished a three-pointer with 1.8 seconds to go as Notre Dame stormed back from a 15-point second-half deficit for a 77-76 victory over North Carolina on Monday night in South Bend, Ind.
Laszewski took a kick-out pass to the left wing off of Rex Pflueger's offensive rebound for the game-winner.
Prentiss Hubb scored 15 of his 20 points in the second half and dealt eight assists for the Fighting Irish (16-10, 7-8 Atlantic Coast Conference), who trailed 64-49 with 8:37 remaining.
T.J. Gibbs added 14 points, and John Mooney picked up his nation-leading 21st double-double.
Freshman Cole Anthony had 23 points and six assists for the Tar Heels (10-16, 3-12), but he air-balled a three-pointer with 21 seconds left.
North Carolina has lost a season-high six straight games.
Penn State up to No. 9
Penn State moved up to No. 9 in the latest Associated Press men's poll, tying the 1995-96 and 1953-54 teams for the highest ranking in program history.
The Nittany Lions are one of just three ranked Big Ten teams. The others are No. 7 Maryland, No. 20 Iowa and No. 25 Ohio State.
The top five are Baylor, Gonzaga, Kansas, San Diego State and Dayton. Daytona has its highest ranking since reaching No. 2 in 1956.
"We're trying to win a national championship," Dayton guard Jalen Crutcher said. "We feel like that there's no team in the country we can't beat."
Kansas plays at Baylor on Saturday in a game with huge Big 12 and NCAA tournament implications. Kansas played Iowa State on Monday night while Baylor plays at Oklahoma on Tuesday night.
UConn women No. 6 (!)
For the first time since George W. Bush was president, the UConn women's basketball team is not one of the nation's top five teams according to the AP poll.
Following a lopsided loss to South Carolina last week, the Huskies fell to No. 6 nationally, behind South Carolina, Oregon, Baylor, Stanford and Louisville. Geno Auriemma's team had not previously stood outside the top five since the morning of Feb. 5, 2007.
The Huskies spent 4,760 consecutive days in the top five.
UConn has been ranked in the top 10 since March 14, 2005.
