George Mason scored three goals in dead-ball situations and defeated George Washington, 5-0, in the Capital Collegiate Conference soccer opener for both teams yesterday at RFK Stadium's auxiliary field.

The Patriots (4-0) took advantage of their opponents' disorganized defense, outshooting the Colonials, 12-5, and keeping play in GW's half most of the game. The game was the first between George Mason Coach Richard Broad and new GW Coach Tony Vecchione, who formerly served as Broad's assistant.

Freshman wing John McIntyre, formerly of Oakland Mills High School, gave Mason a 1-0 lead after 18 minutes when he picked up a rebound off a free kick in front of the net and beat GW goalie Leonardo Costas in the right-hand corner.

Defender Mike Reynolds, who shut down Yarid Aklilu, the Colonials' main scoring threat, scored the second goal off Adolfo Alvarez's free kick at 44 minutes. Breaking down the center, Reynolds headed the cross from the right side into the net to make it 2-0 at the half.

George Mason scored again six minutes after intermission when junior midfielder Mark LeMair scored on a breakaway.

All-South midfielder Scott Shiffert scored the fourth goal when he redirected Hugh Ickrath's corner kick at 75 minutes. Senior Colin Kerr who scored 10 goals last year, closed out the scoring on a 15-yard drive from the right side with four minutes left.
