Eleanor Roosevelt had three first-half touchdowns nullified because of penalties, but it hardly mattered as the eighth-ranked Raiders routed Patterson of Baltimore City, 52-6, in a Maryland 4A semifinal game this afternoon.

The game was part of a Maryland playoff doubleheader at Polytechnic High School. In the second game, No. 14 Howard (10-2) lost to Edmondson of Baltimore, 37-15.

Roosevelt (11-1) will play No. 6 Gaithersburg (11-1) in the 4A final next weekend at Maryland's Byrd Stadium. The Raiders have won 16 of their last 17 games. Edmondson (12-0) will play defending champion Urbana in the 2A final.

Junior running back Edwin Rios ran for a 70-yard touchdown the first time he touched the ball to give Roosevelt a 7-0 advantage just 52 seconds into the game. Rios finished with 132 yards and two touchdowns on 13 carries, and he also intercepted a pass.

The Raiders' defense was the main story. After allowing a 74-yard touchdown run to Rashidi Scott early in the first quarter, the Raiders did not allow Patterson to advance past midfield. Roosevelt had two interceptions and recovered two fumbles, and turned the four turnovers into four touchdowns.

"We know that our offense at any given time can go for a touchdown," Roosevelt senior offensive and defensive lineman Delano Dryden said. "But if we come to play defense, we feel that we can stop anybody."

In the second game, Howard took a 7-0 halftime lead on a 35-yard touchdown run by Penn State-bound senior Gerald Smith. But Edmondson senior Justus McLeod returned the opening kickoff of the second half 85 yards for a touchdown, and that turned the game around. In the first four minutes of the third quarter, the Redskins recovered two Howard fumbles and scored two more touchdowns to build a 22-7 lead.

* FORESTVILLE 47, CAMBRIDGE-SOUTH DORCHESTER 7: Junior running back-cornerback Larry McClain rushed for 241 yards and 2 touchdowns on 13 carries and intercepted two passes, as the 17th-ranked Knights defeated the Dorchester County school in a Maryland 1A semifinal in Forestville.

The Knights (10-2) advance to the 1A final and will play Brunswick (10-2) of Frederick County Friday at Byrd Stadium. Forestville lost in the 1A final last season to Oakland Mills, 15-12.

Junior running back Ed Garnes added 176 yards and three touchdowns on 20 carries, as Forestville gained 512 yards on the ground and 571 yards total. The two-time Prince George's 2A/1A champion scored on its final four possessions in the first half on runs of 17 and 14 yards by Garnes, an 88-yard run by McClain and a 28-yard pass from quarterback Steve Crudup to Pierre Hawkins.

"We knew the road to Byrd goes through Cambridge," Forestville Coach Michael Mayo said. "We had to get over the Cambridge mystique. We felt if we came out and played hard we could beat them."

* PARK VIEW 56, CHARLOTTESVILLE 22: The Virginia AA Northwestern District champion advanced in the Division 4 semifinal with its 12th straight victory. The fifth-ranked Sterling school, which has scored a state-record 497 points this season, will play at Lafayette of Williamsburg on Saturday at 1:30 p.m. Lafayette advanced by defeating No. 18 Spotsylvania, 13-3.
