Elizabeth Williams had 16 points and five blocks to help No. 4 Duke beat St. John's 60-42 on Sunday in the seventh annual Maggie Dixon Classic.
Haley Peters added 11 points for the Blue Devils (8-0), who are off for the next week for exams. The two teams met last season in the NCAA tournament regional semifinals and the Blue Devils routed the Red Storm 74-47.
Nadirah McKenith had 19 points to lead St. John's (4-3).
Trailing 11-10 early on, Duke scored 15 of the next 17 points to take control. Williams' three-point play made it 17-11 and Alexis Jones' layup capped the burst. St. John's cut its deficit to nine before Duke closed the half with an 8-2 run to go up 36-21.
McKenith tried to keep the Red Storm in the game, scoring the team's first 12 points in the second half, but St. John's couldn't get within single digits because of Williams.
