Kevin Larsen, Montrose Christian (Doug Kapustin/FOR THE WASHINGTON POST)

UPDATED, 6 p.m.

Chalk up a big one for George Washington Coach Mike Lonergan and his staff.

The Colonials landed Montrose Christian center Kevin Larsen on Monday, adding to a significant recruiting haul that also includes All-Met guards Kethan Savage of Episcopal and Joe McDonald of Landon.

GW also has signed 6-5 Argentine swingman Patricio Garino of Montverde (Fla.) Academy and 6-9 forward Paris Maragkos, a Greek native who played at the Blue Ridge School in St. George, Va. The Colonials also will add forward Isaiah Armwood, a former Montrose Christian player, to the roster after he sat out this season following his transfer from Villanova.

Larsen, who is 6 feet 9 and 240 pounds, is a Denmark native who played two seasons at Montrose Christian. During that time, he improved tremendously, averaging 7.5 points this past season as the Mustangs went 21-3.

“A lot of it had to do with his conditioning,” Montrose Christian Coach Stu Vetter said. “He lost about 30 pounds since he came to Montrose. He was a very skilled player from the beginning.”

Providence and Temple were among the other schools to offer scholarships to Larsen.

“I think he just felt very comfortable at GW,” Vetter said. “I think it’s a good fit for him. They have an outstanding recruiting class coming in and he can join that class and do some great things. He’s a player who is going to get better and better.”

In a statement released by the school, Lonergan said of Larsen, “Kevin has the size and strength to be an inside presence on both ends of the court. He is a great passer and a very unselfish player. He is fundamentally sound and should have an immediate impact on our program.”

Also Monday, Montrose Christian forward Cedric Blossom signed his letter-of-intent to play for Morgan State.

Montrose Christian All-Met forward Justin Anderson signed with Virginia last fall, but it is still unclear what All-Met forward Michael Carrera plans to do next year. Vetter said that interest in Carrera has picked up and he has added scholarship offers from Pittsburgh and Illinois, with interest from Duke.

“His family is coming [from Venezuela] in the next week or two,” Vetter said. “They’re going to sit down and talk about it.”

Also, Vetter said that junior forward Ishmail Wainright continues to stockpile offers, the latest coming from Ohio State and Duke.

“He’s got offers from just about everybody,” Vetter said.
