WASHINGTON -- After Georgetown's big men showed what they could do in the Hoyas' first three games, the backcourt decided to chip in on offense.

Kevin Braswell and Gerald Riley combined for 35 points to lead the Hoyas to a 91-40 rout of Towson in the John Thompson Classic at McDonough Arena on Saturday night.

Braswell, who entered averaging only 10 points, scored 21. Riley had 14 after scoring a total of seven previously.

"I wanted to get the guys going before we enter stronger competition," Braswell said. "My shot was there today, so I hit it."

Four other players, including Gerald Riley with 14 points, scored in double figures for Georgetown (3-1).

The 51-point margin fell short of Georgetown's 61-point win over Marymount in its season-opener. Towson (1-2) is 2-12 against Big East teams. It was the first meeting between the teams.

Georgetown dominated from the opening minutes, largely a result of its noticeable height advantage. The Hoyas' starting front line featured 7-foot Wesley Wilson, 6-8 Michael Sweetney and 6-8 Victor Samnick. The Tigers' tallest player was 6-8 Mike Shin.

Georgetown blocked 14 shots and outrebounded Towson, 46-35. Plus, the Hoyas forced Towson into a season-high 33 turnovers, and held it to 13-of-50 shooting from the field.

Georgetown, which led 49-23 at halftime, opened the second half with a 10-4 spurt and stretched the lead to as many as 55 points.

"We did everything we've been practicing," said Georgetown coach Craig Esherick. "We pressured the ball on the dribble. We denied the passing lane. We contested shots. The effort was there the whole game, and I couldn't be happier with how we played defense."

Braswell scored 18 points in the first half, propelling Georgetown to a 49-23 halftime lead. The Hoyas opened the second half with a 10-4 spurt and weren't threatened after that, stretching the lead to as many as 55 points.

Calvin Dotson led Towson with 11 points. The teams used a wider foul lane based on NCAA experimental rules.
