Sam Sumo scored his 20th goal of the season, breaking the George Mason single-season scoring record, as the Patriots, undefeated and ranked ninth in the nation in two polls, defeated Howard, 2-0, in college soccer yesterday at Turkey Thicket park.

Sumo, a 20-year-old freshman striker from Monrovia, Liberia, scored the Patriots' second goal at 75:00 when he headed Doug Bradley's corner kick past Bison goalkeeper Njie Sherriff.

"Everybody missed the ball," said Sumo. "And it came right to me. It was beautiful."

In 12 games, Sumo has 42 points (20 goals, two assists). His goal broke the George Mason record he shared with Paul Ricaurte, who scored 19 as a sophomore in 1969; John Fenton, who had the same number as a freshman in 1973, and Colin Kerr, who tied the record in '83 as a senior.

With eight games remaining, Sumo could become the NCAA's all-time freshman scoring leader. Although the NCAA does not keep such statistics, Michael King of Fairleigh Dickinson, who scored 31 goals in 1982, is considered to have the record.

After a closely played first half, forward Andy Hay gave the Patriots the lead 10 minutes into the second half when he took a pass in the air from Bruce Lobdell and redirected it into the net.

That goal originated with Sumo. With Howard's defenders drawn up the field, Sumo played the ball ahead to Lobdell. Lobdell's cross was taken by Hay, who had cut for the near post.

"The goals our opponents are scoring against us are coming when they slip by our defenders," said Coach Keith Tucker, whose Bison are 2-5-1.

Although George Mason controlled play through the midfield, Howard occasionally threatened when its quick forwards, Phillip Gyau and Peter Prom, outran Patriot defenders on the sideline. American 3, George Washington 1
