WASHINGTON (Ticker) -- Freshman Dedrick Finn sank four 3-pointers in the second half as No. 19 Xavier finally found the range from outside to defeat George Washington, 80-68, in an Atlantic 10 Conference matchup.
Finn finished with 15 points and Lionel Chalmers added 17 for the Musketeers (16-4, 7-1 A-10 West), who led at halftime, 31-30, despite poor outside shooting and the failure to contain Colonials guard Chris Monroe.
Xavier turned things around in the second period, as Finn drained three 3-pointers in a 12-2 run to start the half, and outscored George Washington by a 27-14 margin over the final nine minutes.
"I felt like if we could just settle down and defend, we would be in good shape," Xavier coach Thad Matta said. "We had to shoot the ball. I had great faith that Dedrick Finn and Lionel Chalmers would knock some shots down, and they did."
Senior forward David West notched his 61st career double-double with 13 points and 13 rebounds for Xavier, which won its seventh straight game.
Late in the first half, West became the all-time leading rebounder in Atlantic 10 history with 1,161, surpassing Mike Brown, who played for George Washington from 1982-85.
"I didn't know I was that close to it, it's a standard that someone will have to break some day," West said.
Monroe collected 13 of his 17 points in the first half for the Colonials (8-11, 2-6), who had a two-game winning streak halted and lost for the seventh time in their past nine.
The Musketeers shot just 43 percent (26-of-61) from the field, including a woeful 1-of-9 from behind the arc in the first half. They stepped it up in the second, knocking down 6-of-13 from long range.
George Washington shot 53 percent (25-of-47) from the floor.
"This was a confidence builder, and we have some tough games coming up," Monroe said. "This game will prepare us for the road ahead."
Chalmers, who was playing just his second game after missing the entire month of January due to injury, was 6-of-11 from the floor in 20 minutes.
After Finn's 3-pointer two minutes into the second half gave Xavier a 43-32 advantage, the Colonials chipped away and took a brief 54-53 edge after two free throws by T.J. Thompson with 8:52 to go.
"I think we were up one and Pops (Mensah-Bonsu) got a big time rebound, but unfortunately we lost the ball," George Washington coach Karl Hobbs said. "That was the difference in the game, that killed the momentum, and from that point, it was a real struggle to get over the hump."
But Xavier had an answer, as Romain Sato hit a pair of free throws and a layup around a 3-pointer by Finn and West sank two foul shots for a 62-54 cushion.
George Washington closed within 62-59 on a bucket by Mike Hall with 5:22 to play, but a 15-0 outburst by the Musketeers decided the issue.
Sato went 11-of-12 from the foul line and scored 15 points and Anthony Myles added 11 for Xavier, which forced 19 turnovers and committed just nine while posting its fourth straight road win.
Thompson netted 14 points, Omar Williams 13 and nine rebounds and Mensah-Bonsu contributed 13 for the youthful Colonials, who start three freshmen and two sophomores.
"We're definitely maturing with every game," Mensah-Bonsu said. "I'm hoping that sooner or later we can pull out one of these against a tough team."
