Two of the highest-scoring teams in the metropolitan area, 14th-ranked Great Mills (11-0) and 19th-ranked Damascus (9-2), will meet for the Maryland Class B championship at Great Mills at 7:30 tonight.

In contrast, the 7:30 Class A final tonight at Towson State College, between 15th-ranked Richard Montgomery (9-2) and Loch Raven (10-1) of Baltimore County, may be decided by a touchdown or less.

Loch Raven gained a berth in its final and spoiled an all-area matchup by defeating last year's state runner-up, Thomas Stone, 22-16, in overtime. Loch Raven, a good defensive team, stopped Stone four times from the 10-yard line in overtime.

Richard Montgomery, a 13-10 victor over Northeast in its semifinal, has surrendered 10 points or more only three times this season. The Rockets have allowed only 53 points and recorded five shutouts.

Great Mills and Damascus had excellent semifinal games. Damascus scored all of its points in the middle two periods and defeated previously unbeaten Sparrows Point, 34-18. With backs Bill Hauptman and Jeff Rachel running for 206 yards, Damascus, averaging 22.8 points a game, gained 327 yards.

Great Mills, which routed Easton, 47-8, in its semifinal, gained 332 yards, 283 on the ground. Fullback Thomas Chase, who had 138 yards and scored twice, tailback Dwayne Humenik, voted the most valuable player in the Southern Maryland Athletic Conference, and quarterback William Smith will be players Damascus will watch closely.
