St. John's stopped George Mason, 1-0, yesterday in the Washington Metropolitan Independent Soccer League A Division championship at Paul VI, in effect making a prophet of losing coach Mark Wallace, who had preached that offense puts people in the stands but defense wins championships.

In the B Division title game, German School scored 12 seconds into the contest and easily handled St. Anselm's, 4-0.

St. John's (14-4-6) had advanced to the title game last year but lost to Paul VI, 3-2. This year the Cadets left no doubt as to who was in charge as they completely dominated the smaller Mustangs. George Mason tried to stifle the Cadets' attack by clogging up the midfield and backfield. The ploy worked in the first half but it also prevented George Mason from building any offensive continuity.

Noticing that the Mustangs were playing two extra men back, the Cadets in the second half began using the width of the field to advantage. St. John's spread George Mason out and at 55:00, Anthony Castro scored. Making fullback Brent Johnson bite on a fake, Castro then turned and fired past goalie Darren King.

In the B championship, German School had its four goals by halftime. This game was in marked contrast to last week's regular season championship match between the two schools. In that game, German School (10-1-2) trailed, 2-0, at halftime before Boris Pregel rallied his team with three second-half goals for a 4-3 win.

Yesterday, Pregel scored the first of his two goals before St. Anselm's (17-3-1) got settled on defense. Pregel's first score came off a pass from Kay Dwinger, who also scored on a direct kick. Bertram Stemmler, with an assist from Dirk Spielvogel, made it 2-0 at 11:00.

German's Holger Griebl tightly marked St. Anselm's leading scorer, Dave Walters.
