CLEMSON, S.C. (AP) — Duke coach Mike Krzyzewski has gotten more than he's expected out of the Blue Devils the past couple of weeks with Marvin Bagley III out. And he's certain it will pay dividends down the stretch once Duke's leading scorer and rebounder returns.

Gary Trent Jr. hit three foul shots with 1:31 left to put No. 12 Duke ahead for good, and the Blue Devils won their third straight with Bagley on the sidelines, 66-57 over 11th-ranked Clemson on Sunday.

"For us, that's three wins with arguably as talented a kid as there is in the country out," Kzyzewski said.

Krzyzewski said Bagley's right knee sprain is improving. The coach said it's unsure when Bagley will be back, but "it'll be soon."

That won't be good news for Duke's opponents down the stretch, especially if the Blue Devils show the toughness they displayed at Clemson.

The Blue Devils gave up all of their 10-point lead over a six-minute stretch when the Tigers tied it at 57 on David Skara's jumper. That's when Trent was off the mark on his 3 from the right corner, but got fouled by Clemson reserve Scott Spencer.

Trent's first shot rattled around before falling through and he swished the next two for Duke (22-5, 10-4 Atlantic Coast Conference). The Blue Devils outscored the Tigers 9-0 the final 90 seconds.

Wendell Carter Jr. followed Trent's foul shots with an inside bucket, and the Tigers (20-6, 9-5) could not respond in losing for the first time at home this season.

"Some of these young guys grew up a little bit today," Kzyzewski said.

Grayson Allen had 19 points for Duke, all but two in the opening half. Carter had 15 points and 10 rebounds while Trevon Duval had 12 and Trent scored 11.

"We're becoming a team," Allen said. "We're coming together."

Marcquise Reed and Elijah Thomas led Clemson with 13 points apiece. Thomas also had 15 rebounds for his seventh double-double of the year.

The Tigers were also without one of their starters in point guard Shelton Mitchell, who suffered a concussion in a loss to Florida State this past Wednesday night. Clemson coach Brad Brownell said Mitchell's absence might have disrupted the team's rhythm, but not enough that the starting backcourt in Reed and Gabe DeVoe should have gone a combined 4 of 24 shooting. Their 16 points combined were 13 fewer than their average this season.

"Those nights happen," Brownell said.

It was the first time the Tigers had lost consecutive games this season.
