Otto Porter Jr. scored 21 points and Markel Starks added 16 as No. 15 Georgetown downed 18th-ranked Marquette, 63-55, at Verizon Center.

Nate Lubick added 10 points and helped limit Marquette's two leading scorers, Vander Blue and Davante Gardner, to nine total points.

The Hoyas (18-4, 8-3 Big East) have rattled off six consecutive wins to pull even with Marquette for second place in the conference, a half-game behind Syracuse.

The Golden Eagles (17-6, 8-3) received 13 points from Jamil Wilson and 11 from Chris Otule, but committed 19 turnovers as their two-game win streak came to an end.

"I'm not sure you can win in Division I at home or on the road with those type of numbers," Marquette head coach Buzz Williams said of the giveaways.

Georgetown made five 3-pointers in the first half and scored the last seven points -- three coming on a deep make by D'Vauntes Smith-Rivera -- to enter the break with a 33-23 cushion.

The Golden Eagles were within 37-34 after Wilson drained a 3-pointer seven minutes into the second half. They had the ball with a chance to tie, but Gardner lost the handle out of bounds. Williams disagreed with the call, thinking a Georgetown player knocked it out, and was whistled for a technical foul.

Porter made the subsequent free throws and followed with a jumper to start an 8-1 run that pushed the margin back to double digits near the midway point.

"He's one of the best players in the country," Georgetown head coach John Thompson said of Porter. "He's consistently shown that. ... He takes pride in and excels at every aspect of the game."

Marquette never fully recovered after Williams' technical and trailed by at least eight points to rest of the way.
