Nate Lubick had a good day, D'Angelo Harrison did not, and coach John Thompson III his 200th victory at Georgetown with a 68-56 win over St. John’s on Saturday afternoon.

Lubick scored a career-high 16 points on 8 of 10 shooting, added 10 rebounds and is shooting 72 percent (31 of 43) over the last six games for the Hoyas (16-4, 6-3 Big East), which extended their winning streak to four games and swept the season series between the teams.

“Any coach would appreciate someone like him,” St. John’s coach Steve Lavin said. “He’s all about the team, he’s a grinder, he adds great value in so many ways at both ends of the floor. I thought he was really the key to the game in terms of Georgetown’s success.”

Thompson was equally impressed with his junior forward, who’s previous career-high of 13 points came on Dec. 12 against Texas.

“He’s been playing at a very high level for a long time now, to tell you the truth,” Thompson said. “When we need something done, he gets a rebound, makes an assist, gets a basket. He’s been doing that consistently and tonight was no exception.”

The Red Storm (14-8, 6-4), meanwhile, shot just 32 percent (20 of 63) from the field in having their five-game winning streak come to an end.

Harrison, who entered the game second in the conference averaging 19.7 points, was limited to two points and missed all nine of his field goal attempts three weeks after he was held to seven points on 3 of 12 shooting in Georgetown’s 67-51 win in New York on Jan. 12.

Despite the fact that his team has now held Harrison to his two lowest-scoring games of the season, Thompson had no clear answer as to why his team has enjoyed so much success against the sophomore.

“I think we just got lucky,” Thompson said. “We knew going into this game that we have to stop him. Everyone has to know where he is whenever he’s on the court. Our guys happened to do a good job and he just happened to have two bad games. I don’t think there’s a secret formula.”

Markel Starks had 12 points on four 3-pointers, Jabril Trawick had 12 points and Otto Porter added 11 points and seven rebounds for the Hoyas, which held a 41-34 rebounding edge, including a 21-9 advantage in the first half.

Georgetown took a 39-28 lead into halftime as the Red Storm were unable to get much production outside of Phil Greene VI, who had 10 of his 12 points in the opening half. A 21-8 run by the Hoyas gave them a 24-15 lead with 9:34 remaining in the first half, and a short jumper by Lubick extended the advantage to 39-24 with 1:54 to play.

“Georgetown really won this game in the first half with the way in which they dominated us with their physicality and purposeful play,” Lavin said. “In the Big East, on the road against a quality team like Georgetown, you have to have a better effort for 40 minutes. In this league, there’s such a small margin for error. If you have a couple lapses in play, or you go a half where you don’t play at a high level, then you’re going to come out with a (loss) most nights.”

JaKarr Sampson had 18 points and eight rebounds to lead St. John’s, which could draw no closer than seven in the second half.

Red Storm guard Jamal Branch, who was helped to the bench after crashing to the floor under the Red Storm basket with 2:38 remaining in the game, was diagnosed with a sprained left knee. He was expected to travel with the team to New York, and his status for Wednesday’s game against Connecticut was unknown.
