Derrick Jackson and Al Dutch keyed a 120 spurt midway through the first half as Georgetown broke open the game en route to a 69-65 victory over Holy Cross.
The victory raised the Hoyas' record to 11-3. It was Holy Cross' second defeat in 14 starts and its first home loss of the season.
Georgetown trailed by a point at halftime before scoring eight of the first 10 points in the second half to take a 39-34 lead.
The Crusaders fought back to a 49-49 deadlock with 10:13 to play. Then steals by Georgetown reserves Steve Martin and Mike McDermott touched off the string of 12 unanswered points over the next four minutes.
When that was over, the Hoyas led, 61-49. Jackson scored six and Dutch added four points during the surge.
Holy Cross, which had been averaging nearly 90 points a game, pulled within four, 69-65, with 14 seconds left but missed three straight shots. Georgetown got the rebound and held on for the victory.
"I told the team before the game to play the scoreboard and clock, not the crowd," Hoya coach John Thompson said. "We kept out compromise and played excellent defense."
The Hoyas shot 59 per cent from the floor for the game, more than making up for a 15-8 disadvantage in free throws attempted. Dutch fin- ished with 23 points and 11 rebounds for game highs in both departments.
Holy Cross freshman guard Ron Perry, the nation's No. 19 major college scorer hit only nine of 22 shots but still tied teammate Chris Potter for team honors with 20 points.
