Otto Porter had 16 points and 13 rebounds, and No. 15 Georgetown pulled away late in the first half Saturday in a 65-48 win over D.C. neighbor American.

Greg Whittington added 13 points for the Hoyas (10-1), who took advantage of the sizable talent gap between the Big East school and the Eagles from the Patriot League. Georgetown has a nine-game winning streak over American, its last loss coming 30 years ago when Patrick Ewing and Co. lost by one point in what still stands as the biggest intra-city upset in the nation's capital.

The Hoyas have won seven straight since an overtime loss to then-No. 1 Indiana. Georgetown now has a two-week break before opening its conference schedule at Marquette.

Daniel Munoz scored 15 points to lead the Eagles (4-8).
