WASHINGTON (AP) -- Lesley Walker scored 13 points for Georgetown (7-5, 0-1) but No. 1 Connecticut hung on to defeat Georgetown, 87-48.

Georgetown has dropped the first two games in a series of four straight against top 20 teams. The Hoyas had won four straight.

"This is a tough stretch for us," Georgetown coach Patrick Knapp said. "Complaining and moaning won't get it done. Hard work will.

This could be demoralizing - if we let it."

Connecticut led 6-1 but Walker hit two free throws with 14:41 left in the half to give Georgetown a 7-6 lead.

Connecticut's Kennitra Johnson's 3-pointer 40 seconds later started an 18-5 run over the next 5:41 that put Connecticut in command.

Johnson had two 3-pointers in the run, which also featured four points each from Shea Ralph and Swintayla Cash.

Georgetown was held to 19-for-60 shooting from the field.

Shea Ralph scored 18 points and Asjha Jones added 15 for Connecticut.

Swintayla Cash added 11 points and 15 rebounds for the Huskies (11-0 overall, 2-0 Big East), who have won 12 straight.

"They weren't getting a lot of second shots," Connecticut coach Geno Auriemma, whose team outrebounded the Hoyas 46-35.
