DURHAM, N.C. - Duke's rebounding made up for its poor shooting.
Haley Peters scored 14 points to help the seventh-ranked Blue Devils beat No. 13 Purdue 64-53 on Thursday night. Duke, which shot 37 percent from the field (26 for 70) and had a 50-32 rebounding edge, won for the 50th time in 51 home games and extended its school-record winning streak at Cameron Indoor Stadium to 27 games.
''I just really like how we came out in the second half: our tenacity, our physical play and how we dictated that,'' Duke coach Joanne P. McCallie said. ''I just like how we played. We played very, very aggressive.''
Courtney Moses scored 17 points to lead Purdue (6-1), which fell to 0-5 all-time the ACC/Big Ten Challenge. Brittany Rayburn added 16 points for the Boilermakers.
The Blue Devils finished with a 24-9 advantage in offensive rebounds, leading to a 14-5 edge in second-chance points.
''It was an opportunity for us to come in and make something happen,'' Purdue coach Sharon Versyp said. ''I thought for about 30 minutes we played pretty well, and then they just dominated on the boards. That pretty much turned the tide.''
Elizabeth Williams had nine points on 2-for-17 shooting, but grabbed a school freshman-record 17 rebounds for Duke. Her presence inside, where the Blue Devils outscored Purdue 38-24, produced scoring opportunities for teammates.
''Really, they sagged off and doubled E,'' Peters said. ''That's just a great testament to everything E has done already this year. They were sagging off me, and I was open in the high post. I had some open looks.''
Purdue took a 40-39 lead on a 3-pointer by Antionette Howard with 12 minutes remaining, but Duke answered with a 13-2 run.
The Blue Devils scored inside on six consecutive possessions during the spurt and never led by fewer than six points the rest of the way. Reserve forward Allison Vernerey, who played just one minute in the first half, had three layups during the run.
The Boilermakers tried to rally with long-range shooting, but they made just 3 of 15 on 3s in the second half.
''We just settled for outside shots, and we were only getting one shot,'' Moses said. ''That was the difference. We weren't getting any offensive boards.''
Purdue finished 7 for 25 from 3-point range. The Blue Devils were just 1 for 4 on 3s, and they didn't even attempt one in the second half.
''It was put your head down and go and get into that paint,'' McCallie said.
Duke played its first game without starting guard Shay Selby, who has been suspended indefinitely for a violation of team rules.
The Blue Devils led by as many as six points in the first half, and they carried a 30-28 lead into halftime.
