Georgetown's Jonathan Wallace, right, drives past South Florida's Kentrell Gransberry. Georgetown won, 63-53, on Tuesday night in Washington.

Washington ? The worst team in the Big East was leading the conference’s best team by nine points late the first half. South Florida was shooting 77 percent. One player, DuJuan Summers, had accounted for four of Georgetown’s meager tally of five baskets.

Enough of that craziness. The Bulls missed their next nine shots. The Hoyas went on a 12-0 run to take the lead for good. Summers finished with a career-high 24 points, and No. 6 Georgetown did just enough in the second half Tuesday night to hold on for a 63-53 victory.

Summers made eight of 13 field goals, including 4-of-8 three-pointers, and had nine rebounds to lead the Hoyas (19-2, 9-1) to their sixth straight win and 18th in a row at home. Roy Hibbert, who had his hands full with Kentrell Gransberry, missed his first three shots but finished with 13 points on 5-for-9 shooting and eight rebounds.

As for the rest of the team? They shot 9-for-34, and no one had more than one field goal until Jessie Sapp’s three-pointer with 11 minutes to play. Overall, the Hoyas shot just 39 percent, the worst performance of the season for a team that entered the game leading the Big East with a 50.3 percent average.

Dominique Jones scored 15 points, and Gransberry had 13 points and nine rebounds for the Bulls (10-13, 1-9), who have lost nine straight.
