KANSAS CITY, Mo. — Jeff Withey scored 17 points and top-seeded Kansas struggled to put away scrappy Western Kentucky, but avoided what would have been the biggest upset on a day full of them in the NCAA tournament for a 64-57 win.

The Jayhawks (30-5), flummoxed by the Hilltoppers’ full-court pressure, trailed 31-30 at halftime. Kansas eventually built an 11-point lead in the second half, but couldn’t put Western Kentucky away until Ben McLemore’s two foul shots with 11 seconds left in the game.

San Diego State 70, Oklahoma 55

PHILADELPHIA — Jamaal Franklin scored 21 points, James Rahon had 17 and San Diego State earned its third NCAA tournament victory.

The Aztecs (23-10) did nothing spectacular, but everything well and used a modest 8-0 run late in the second half to snap a tie game and take control.

Romero Osby scored 22 points for the 10th-seeded Sooners (20-12).

North Carolina 78, Villanova 71

KANSAS CITY, Mo. — P.J. Hairston scored 23 points, James Michael McAdoo added 17 and North Carolina unleashed a flurry of 3-pointers to subdue gritty Villanova.

The never-say-die Wildcats (20-14) erased a 20-point deficit that North Carolina built in the first half and then nearly climbed out of a nine-point hole in the final minutes after the Tar Heels hit three consecutive 3s and once again appeared to take control.

Florida 79, Nothwestern State 47

AUSTIN, Texas — Erik Murphy had 18 points to lead four Florida players in double figures and the Gators shut down the NCAA’s highest-scoring team.

No. 3 seed Florida turned this one into a rout with a 19-1 run in the second half and held the 14th-seeded Demons (23-9) to their fewest points this season — 34 below their average.

Minnesota 83, UCLA 63

AUSTIN, Texas — Andre Hollins scored 28 points and Minnesota rolled past punchless UCLA in what could be Bruins freshman Shabazz Muhammad’s last in college and coach Ben Howland’s final one leading the program.

Austin Hollins scored 16 for the 11th-seeded Gophers (21-12). The Gophers eased some pressure on coach Tubby Smith by giving him his first NCAA tournament win in six seasons.

East Regional Indiana 83, James Madison 62

DAYTON, Ohio — Freshman Yogi Ferrell scored 14 points in the first six minutes as top-seeded Indiana slam dunked its way past James Madison.

Not taking any chances with a No. 16 seed, the Hoosiers (28-6) started fast and built a 33-point lead in the second half over the Dukes (21-15) and opened the tourney with a statement they intend to be around for a while.

Temple 76, North Carolina State 72

DAYTON, Ohio — Khalif Wyatt scored 31 points, finishing the game with an injured left thumb that had him grimacing before his clinching free throws, and Temple broke with its one-and-done NCAA tournament trend.

The ninth-seeded Owls (24-9) opened a 17-point lead before Wyatt — the Atlantic 10’s player of the year and top scorer — hurt his left thumb and left the game briefly, returning with black tape on the non-shooting hand.

Miami 78, Pacific 49

AUSTIN, Texas — Durand Scott had 21 points and Miami had a triumphant return to the NCAA tournament.

The Hurricanes (28-6), who may be even better than their No. 2 seed in the East Regional would indicate, put the game out of reach with a 14-0 run midway through the first half of their first NCAA tourney game in five years.

Illinois 57, Colorado 49

AUSTIN, Texas — Brandon Paul and D.J. Richardson made consecutive 3-pointers to give Illinois back the lead with 6 minutes left and the seventh-seeded Illini pulled out a tough win over Colorado.

Illinois led by 16 at halftime only to watch Colorado rip off a 21-2 run in the second to grab the lead. The Illini looked desperate until Paul and Richardson coolly knocked down their shots to put Illinois ahead 48-44.

Midwest Regional Duke 73, Albany 61

PHILADELPHIA — Seth Curry scored 26 points, Mason Plumlee had 23 and second-seeded Duke beat Albany.

The Blue Devils (28-5) will meet seventh-seeded Creighton in the third round Sunday.

Duke shot 58.7 percent (27 of 46), just off its season-beat 60.8 percent against Florida State.

Creighton 67, Cincinnati 63

PHILADELPHIA — Doug McDermott had 27 points and 11 rebounds, and Gregory Echenique scored 13 points to help Creighton hold on.

Ethan Wragge added 12 for the Bluejays, who won their NCAA tournament opener for the second straight year.

West Regional

Mississippi 57, Wisconsin 46

KANSAS CITY, Mo. — Marshall Henderson shook out of a shooting slump and scored 17 points in the second half, giving the Rebels their first NCAA tournament win since 2002.

For the cold-shooting Badgers (23-12), the upset loss snaps a string of six straight first-game victories. Ole Miss (27-8) trailed 25-22 at halftime and Henderson, who led the Southeastern Conference with 20 points a game, had only two points on 1-for-11 shooting.

La Salle 63, Kansas State 61

KANSAS CITY, Mo. — Jerrell Wright made three foul shots in the final 30 seconds, and No. 13 seed La Salle advanced after blowing an 18-point halftime lead to beat fourth-seeded Kansas State.

Wright, who scored a game-high 21 points for the Explorers (22-9), made the first two free throws to give La Salle a 62-61 lead. Kansas State’s Jordan Henriquez missed in the paint at the other end, and Wright made the first of two more free throws with 9.6 seconds to go.

Ohio State 95, Iona 70

DAYTON, Ohio — Sam Thompson had career highs with 20 points and 10 rebounds, part of a dominating performance by Ohio State’s front line against Iona.

The second-seeded Buckeyes (27-7) have won nine straight, including their last five games of the regular season and a run to the Big Ten tournament title.

Iowa State 76, Notre Dame 58

DAYTON, Ohio — Freshman Georges Niang matched a season high with 19 points and Iowa State, showing it can do much more than just fire away from outside the 3-point line, dismantled Notre Dame.

The 10th-seeded Cyclones (23-11) led the nation in 3-pointers this season, but the Cyclones were just as effective from short range in ousting the Fighting Irish (25-10), who played their final game as a member of the Big East and will join the Atlantic Coast Conference next season.
