CHARLOTTE -- Michigan guard Darius Morris’ attempt at a tying shot caromed off the back rim with one second remaining Sunday afternoon, allowing No. 1 seed Duke to advance to the NCAA tournament’s West Regional semifinals with a 73-71 win at Time Warner Cable Arena.

The Blue Devils led by as many as 15 points in the second half, but guard Tim Hardaway Jr. scored seven of his 15 points in the final 3:09 to rally the Wolverines. A Hardaway 3-pointer with 1:27 remaining cut the deficit to 70-69, but Duke freshman guard Kyrie Irving made a 6-foot bank shot against a 1-3-1 zone with 31 seconds left.

Morris drove the lane for a layup with 10 seconds remaining, and Michigan immediately fouled Duke guard Nolan Smith. He made the first of two free throws with 8.6 seconds left, and Morris made a mad rush down the court for an attempt at the tying basket.

His final shot caromed off the rim, leaving Duke to celebrate coach Mike Krzyzewski’s 900th career win. Krzyzewski needs three more wins to break Bob Knight’s Division I record.

DURHAM -- Duke throttled Tennessee-Martin on Saturday and collected a 90-45 victory in the first round of the NCAA women’s tournament at Cameron Indoor Stadium.

Comfortable on their home court, the Blue Devils led 41-31 at halftime, opened a 21-point lead five minutes into the second half and extended that to 47 with 1:17 remaining. They remain undefeated at home this season.

Once the Devils got going, they pounced like an avalanche on a inexperienced Tennessee-Martin program that had reached the tournament for the first time in program history.

CHARLOTTE -- Well, that was a tidy day’s work for the Duke Blue Devils.

With a comforting lack of drama, the top-seeded Blue Devils manhandled Hampton 87-45 today in their opening NCAA tournament game at Time Warner Cable Arena.

It was noteworthy for its efficient workmanship, the return of Kyrie Irving and the fact it moves coach Mike Krzyzewki within three victories of tying his mentor Bob Knight for the most wins ever by a Division I hoops coach.

CHARLOTTE – In less a half-minute Friday afternoon, freshman guard Kyrie Irving sent a shudder through teams in the NCAA tournament who suddenly face an even larger obstacle in Duke.

In his first game back from a toe injury that kept him out 3 ½ months, Irving got aggressive in the closing minutes with an 87-45 win over Hampton already wrapped up for No. 1 seed Duke at Time Warner Cable Arena.

North Carolina's loss to Duke in the ACC championship game this afternoon turned out to be a big problem in the NCAA pairings.

As the No. 2 seed in the East, the Tar Heels do get to start in Charlotte.

But if the top four seeds advance to the regional semifinals in Newark, N.J. (March 25 and 27), the chalk pairings would be UNC vs. Syracuse (3) and Ohio State (1) against Kentucky (4).

Talk about a tough ticket to find.

By contrast, Duke got rewarded for the most part by winning the ACC.

GREENSBORO -- When Duke seniors Nolan Smith and Kyle Singler came off the floor to bear hugs from Mike Krzyzewski in the final minute Sunday, even North Carolina coach Roy Williams stood up and applauded.

Smith and Singler captured their third straight ACC tournament title, the Blue Devils’ 10th in the past 13 years, with a 75-58 defeat of top-seeded North Carolina at the Greensboro Coliseum.

GREENSBORO -- Duke and North Carolina in an ACC championship game.

Makes all the sense in the basketball world, right?

It hasn’t turned out that way since 2001, when Duke won 79-53 in Atlanta.

GREENSBORO -- Duke's 87-71 win over Maryland in an ACC quarterfinal Friday night was impressive, especially considering Duke lost point guard Nolan Smith due to a toe injury (his second toe, to be exact) with a 65-60 lead and 6:48 to go.

GREENSBORO – On a night when one big question was answered for the Duke Blue Devils, another potentially bigger one was raised.

The Kyle Singler question? He’s fine. Singler eased plenty of minds when he opened the Maryland quarterfinal tournament game by hitting a couple of quick jump shots that seemed to sweep away the residue of some off-kilter performances recently.

He wound up with 29 points and looked like Kyle Singler is supposed to look in Duke’s deceptively lopsided 87-71 victory.

But what about Nolan Smith?

GREENSBORO -- Duke did not want to start the postseason this way.

Senior guard Nolan Smith, the ACC player of the year, limped off the court with a toe injury of undetermined severity Friday night late in the Blue Devils’ 87-71 defeat of Maryland in the ACC quarterfinals.

In today’s 3 p.m. semifinal, No. 2 seed Duke will play the winner of Friday’s late game between No. 3 seed Florida State and No. 6 seed Virginia Tech. Blue Devils coach Mike Krzyzewski said he doesn’t know if Smith will play and will have X-rays to determine the seriousness of the injury.
