Alex O'Connell scored nine straight points to help Duke seize a commanding lead in the final minutes ... HALFTIME: Duke 46, Wake Forest 33 Against a much more aggressive team than Pittsburgh and missing the leadership of head coach Mike Krzyzewski, the Blue Devils faced a much bigger test in Wake Forest for their sometimes questionable defense. But with the Demon Deacons struggling with sloppy play, Duke enters the second half with an 46-33 lead, with freshman big man Marvin Bagley III and reserve guard Alex O'Connell combining for 25 points. After a scoreless opening couple of minutes, senior Grayson Allen dished a pass to freshman Bagley for a massive alley-oop. The Demon Deacons responded immediately with a layup as both teams battled for the lead in the first 10 minutes. With Wake Forest up 15-11, a 3-pointer from freshman Gary Trent Jr. with 13:12 on the clock jumpstarted the Blue Devils' offense, sparking a 14-2 run to put Duke up 25-17. But the Demon Deacons weren't shaken by the Blue Devils' surge on offense, with Bryant Crawford responding with a three and a putback jumper at to put Wake within three with 6:38 left in the half. But the freshman trio of Bagley, O'Connell and Trent kept the Blue Devils in control. Nine straight points from O'Connell in less than a minute were part of an 13-5 run to close the half that gave Duke a double-digit lead. Here are a few observations from the first half: Justin Robinson is stepping into a bigger role on the team. With DeLaurier and Bolden sidelined again due to injury, the former walk-on was switched onto the court early before the first media timeout—before O'Connell and Antonio Vrankovic. The Demon Deacons are struggling to stay clean through the first half. Wake Forest committed five fouls in the first five minutes and ended the half with 14. Grayson Allen is taking the reins for Duke as a playmaker. Allen leads the Blue Devils in assists and rebounds and at the half while Trevon Duval has remained largely absent due to an apparent toe injury. Gary Trent Jr. appears to be sick—he spent a while on the bench with a trash can in front of him.
