Seth Curry scored 25 points and Mason Plumlee added 20 points and a career-high-matching 17 rebounds as No. 5 Duke's starters scored all but two of the Blue Devils' points in an 89-71 victory over Minnesota on Thursday in the first round of the Battle 4 Atlantis.
Plumlee was coming off a career-high 28 points on 9-for-11 shooting from the field, 10 of 11 from the free throw line and had nine rebounds in the Blue Devils' previous game, an 88-67 win over Florida Gulf Coast.
Sophomore point guard Quinn Cook had a career-high 17 points for the Blue Devils who extended their regular-season tournament winning streak to 21 games, a run that stretches to the championship game of the 2006 CBE Classic.
Duke (4-0) will face the winner of the first-round game between No. 19 Memphis and VCU in Friday's semifinals.
Rodney Williams had 16 points for the Golden Gophers (4-1), who just couldn't cut into the Blue Devils' lead in the second half.
