NEW YORK — Hollis Thompson scored all of his 20 points in the second half and No. 11 Georgetown snapped a two-game losing streak with a 69-49 victory over St. John's on Sunday at Madison Square Garden.

Thompson, the Big East's leading 3-point shooter at 52.4 percent, missed four from long range in the first half but he only was off on one of his five attempts in the second, including one that broke an 8-0 run that had brought the Red Storm within 48-45 with 6:36 to play.

Jesse Clark had 15 points and freshman Otto Porter added 13 points and 10 rebounds for the Hoyas (14-3, 4-2 Big East), who had lost to West Virginia and Cincinnati after an 11-game winning streak.

Freshman Moe Harkless had 21 points and 10 rebounds for St. John's (8-9, 2-4), but he fouled out with 5:15 to play in the midst of a 12-2 run that gave the Hoyas a 58-47 lead.
