Duke 85, Michigan State 76

Mike Krzyzewski’s emotions began to flow with a few seconds left on the clock, when it was finally certain Duke would extend his last NCAA Tournament run.

He whirled around to face the section where his family was sitting behind him and extended both arms to point their way in celebration. He traded high-fives and hugs with his players, then shared a long postgame hug at midcourt with Michigan State's Tom Izzo after beating his friend in the Hall of Fame coaches’ bittersweet final tussle.

Krzyzewski's retirement will be on hold for several more days at least. The Blue Devils survived a tense finish to beat the Spartans 85-76 on Sunday, earning another trip to the Sweet 16 and giving their coach his latest milestones.

Trailing by five near the 5-minute mark and with their season in peril, the Blue Devils (30-6) responded with one big shot after another, a resilient performance amid uncommon pressure.

It was almost too much for Krzyzewski, who struggled to find the right words to start his postgame news conference.

“You guys were terrific, man,” Krzyzewski told the players sitting alongside him, his voice quavering with emotion. "I'm so — I'm really proud to be your coach.

“It had nothing to do with coaching in those last four or five minutes. It all had to do with heart and togetherness. They followed their hearts and God bless them — we're in the Sweet 16.”

Star freshman Paolo Banchero scored 19 points and muscled in the go-ahead drive through contact with 2:05 left, putting the Blue Devils ahead to stay in the record-extending 1,200th win of Krzyzewski’s career. Duke reached the Sweet 16 for the 26th time under Coach K, who announced last summer that his 42nd season with the Blue Devils would be his last.

Those coaching milestones came against his longtime friend and frequent rival. The 75-year-old Krzyzewski — who has five NCAA titles and a record-tying 12 Final Four appearances — improved to 13-3 against the 67-year-old Izzo, who won the 2000 national championship and has reached eight Final Fours.

Krzyzewski will continue his push for a career-capping championship when the second-seeded Blue Devils head to San Francisco to third-seeded Texas Tech on Thursday in the West Region semifinals.

The Blue Devils shot 61% after halftime and 57% for the game, and they needed every bit of that production to survive against the seventh-seeded Spartans (23-13) in a riveting fight to the final minute.

“It’s the NCAA Tournament, our season’s on the line every single game,” Banchero said. “That’s really all that needs to be said. ... We were like, ‘We’ve got four minutes: we can either lay down or turn it up.’”

The 6-foot-10 Banchero had the biggest basket, putting the ball on the floor and scoring in a mauling drive against the smaller Joey Hauser for the 75-74 lead. Then Jeremy Roach hit a 3-pointer to beat the shot clock for a four-point lead with 1:16 left, sending an already-charged crowd into a full roar.

“I think they showed their truest colors,” Izzo said.

“An average team without a lot of heart might've just drifted into the sunset. And I thought they reached down in Mike Krzyzewski fashion and did an unbelievable job of kind of taking it at us. We just didn’t have enough left.”

Even more impressive, Duke did it all with freshman starter A.J. Griffin sidelined the last 8:24 with an apparent left ankle injury. The Blue Devils closed out the game by outscoring the Spartans 20-6.

Gabe Brown scored 18 points to lead Michigan State, while Tyson Walker scored all 13 of his points after halftime. The Spartans shot 42% for the game and had only one field goal over the final 2 1/2 minutes in possession-by-possession fight as Duke made its move.

“I want to be proud, but at the same time, mad that we're not playing another night," said Spartans big man Marcus Bingham Jr., who had 16 points and 10 rebounds. “I think the guys went out there and played hard from the first half into the second half. We fought. Just some situations, we just didn’t pull through.”

Banchero, a top NBA prospect, and 7-foot-1 Mark Williams (15 points, eight rebounds, five blocks) overpowered the Spartans — who have plenty of length themselves — and showed how good the Blue Devils can be in the front court. Duke was balanced with five double-figure scorers, including Wendell Moore Jr. (15 points), Roach (15) and Trevor Keels (12) — all of whom hit key shots late.

“I knew once we got our foot in the door," Moore said, “there was no looking back from there.”

Izzo, who won the 2000 NCAA title and has eight Final Fours in 27 seasons, acknowledged all the "weird emotions" sure to come for both teams in this game. His team gave itself a chance but couldn't slow the Blue Devils' late push. Izzo fell to 2-4 against Krzyzewski in the NCAA Tournament.

"I'll always pull for Mike," Izzo said. "I think he's done some things that will go down in the lore of basketball. You can remember this game in a lot of ways. My way of remembering it won't be quite as enjoyable, but it will be respectful."

Texas Tech 59, Notre Dame 53

Kevin McCullar made an emphatic dunk with 15 seconds left to cap a 10-1 closing run for No. 3 seed Texas Tech, which beat Notre Dame to advance to the Sweet 16.

Kevin Obanor had 15 points and 15 rebounds, and McCullar and Bryson Williams each scored 14 for Texas Tech (27-9), which made its third round of 16 in the past four tournaments and fifth in school history.

Dane Goodwin scored 14 points for 11th-seeded Notre Dame (24-11), which led 52-49 with just over two minutes left. But the Fighting Irish didn’t make a field goal in the last three minutes and Texas Tech made eight straight free throws in the last 1:56, including two by Obanor that put the Red Raiders ahead 53-52 with 1:10 left.

South Region

Arizona 85, TCU 80 (OT)

Bennedict Mathurin made a 3-pointer to force overtime and scored six more points in the extra session, and top-seeded Arizona outlasted ninth-seeded.

Mathurin finished with 30 points and Christian Koloko scored 28, including a putback dunk that slammed the door on the Horned Frogs with 9 seconds left in OT after Mathurin missed a 3.

Koloko was 12 of 13 from the field, including five dunks, but the rest of the Wildcats were 19 of 55, including 5 of 27 on 3-pointers.

Still, Arizona's two stars did enough for the Wildcats (33-3) to avoid becoming the second No. 1 seed to fall during this tournament's opening weekend. They advanced to Thursday's South Region semifinals in San Antonio, Texas, where they will face fifth-seeded Houston.

Chuck O’Bannon Jr. had 23 points for TCU (21-13) while Mike Miles Jr. and Eddie Lampkin Jr. had 20 apiece. The Horned Frogs were looking to get to the Sweet 16 for the first time.

Houston 68, Illinois 53

Taze Moore scored 21 points, Jamal Shead added 18 and Houston, a Final Four team last season, advanced to the Sweet 16 by beating Illinois, which bowed out in the opening weekend for the second straight year.

The fifth-seeded Cougars (31-5), who lost their two best players to season-ending injuries, are headed home to Texas for the South Region semifinals, which will be in San Antonio, about a three-hour drive from Houston.

Kyler Edwards added 15 points for Houston.

For Illinois, it’s another year of deep disappointment. The fourth-seeded Fighting Illini (23-10) were determined to go farther after being bumped by Loyola Chicago last year. All-American center Kofi Cockburn did his part, scoring 19 points in 38 minutes.

Villanova 71, Ohio State 61

Collin Gillespie scored 20 points, Eric Dixon hit a big 3-pointer late and second-seeded Villanova fended off seventh-seeded Ohio State.

The Wildcats (28-7) earned their eighth trip to the Sweet 16 under Jay Wright after surviving a second-half push from the Buckeyes (20-12), who trimmed a 15-point deficit to two before Villanova regained its footing.

The Wildcats will continue their quest for a third national title in seven seasons when they face 11th-seeded Michigan in the South Region semifinals on Thursday night in San Antonio.

Malachi Branham scored 15 of his 23 points in the second half. E.J. Liddell added 17 in likely his final game with the Buckeyes before heading to the NBA.

East Region

Purdue 81, Texas 71

Jaden Ivey made a critical 3-pointer with 1:01 left and finished with 18 points, and Purdue finally got past Texas coach Chris Beard in March.

Trevion Williams scored 22 points to lead the Boilermakers, who capitalized on a major disparity at the free-throw line to reach the Sweet 16. Purdue had 46 attempts, making 33, while the Longhorns went 7 of 12 on free throws.

The third-seeded Boilermakers (29-7) advanced to an East Region semifinal on Friday in Philadelphia against this year’s out-of-nowhere tourney darling, 15th-seeded Saint Peter’s.

Beard had won each of his two previous NCAA Tournament matchups with coach Matt Painter’s Boilermakers, who had the better seeding each time. He coached both Little Rock and Texas Tech past Purdue.

Marcus Carr led sixth-seeded Texas (22-12) with 23 points and Andrew Jones scored 17.
