WASHINGTON (AP) _ Alexander Koul used his 5-inch height advantage over LaSalle's front line to score 21 points and grab a career-high 16 rebounds in George Washington's 56-52 victory over the Explorers Saturday.

Thanks to the 7-foot Koul's inside presence, the Colonials (9-7, 4-3 Atlantic 10) out-rebounded LaSalle 43-31 and held the Explorers to 31 percent (18-for-58) shooting from the floor.

LaSalle guard Donnie Carr, the second-leading scorer in the nation, finished 10 points below his average with 16 total. But the Explorers (7-8, 2-3) managed to stay in the game and led 47-45 with 2:45 remaining.

Koul tied the game seconds later on his fifth dunk of the contest.

After the teams traded baskets, Koul, who had several key defensive plays down the stretch, put the Colonials ahead for good with a follow-in with 1:30 left.

Yegor Mescheriakov, who scored 16 points, gave the Colonials a four-point cushion with a turnaround shot off the glass with 30 seconds remaining.

Shawn Smith led LaSalle with 18 points.

The Explorer's tallest players inside, 6-7 Travar Johnson and 6-6 Everett Catlin, combined for just eight points and nine rebounds against George Washington, which started three players 6-8 or taller.

J.J. Brade came off the bench to contribute 12 points for the Colonials.

LaSalle fell to 0-5 on the road, and last won a game away from home against American University on Dec. 13, 1995.
