Third-ranked Oxon Hill's highly touted defense met more than its match yesterday in Randallstown's Larry Washington. He rushed for 203 yards in 26 carries as he stiff-armed, bowled over and ran by a defensive unit that had prided itself on bruising opposing running backs.

Oxon Hill had heard about Washington and tried to contain him, but he tore up the Clippers' game plan in leading Randallstown to a 21-7 Maryland Class 4A semifinal victory yesterday at Oxon Hill.

"He is a good back," said Oxon Hill Coach Cliff Haskins. "We knew he was going to sweep to the outside. The main thing is his speed. He is just an excellent back and I wish him luck."

Oxon Hill completed its season at 11-1. Randallstown (12-0) will play Wootton (12-0), which upset top-ranked Springbrook, 20-7, next week for the state championship.

"We've been working hard all year," said Washington. "A lot of people didn't think we had a chance against these {Washington area} teams out here."

But no defense this season has been able to stop Washington, who said he has not decided which college he will attend next year.

The 5-foot-11, 215-pound senior exceeded 100 yards by halftime, but no touchdowns. He danced away from a couple of tackles at the line of scrimmage, cut to the outside and accelerated en route to a 69-yard touchdown on his first handoff of the second half as the Rams went up 14-7.

Oxon Hill forgot about the other Rams players, particularly Washington's backfield partner, Dan Dorsey. Dorsey averaged nearly five yards a carry in gaining 73 yards on 15 handoffs.

"He's been running good all year," said Washington. "This was his first season on varsity. We just have a good running game; we don't pass much."

That was another advantage the Rams had yesterday, as they caught Oxon Hill's secondary napping early in the second quarter. Quarterback Shaun Poulton lofted a beautiful 29-yard touchdown pass to Tyrone Wells, who beat three defenders to culminate a 12-play, 80-yard drive that tied the game at 7-7.

"They were all keying on {Washington} and they were so far up on the play that I just dropped the pass in on them," said Poulton.

Oxon Hill had recorded seven shutouts this season, but the Rams' confidence remained high as they challenged what many people regarded as the fiercest-hitting team in Prince George's 4A.

"I figure that we can score against anybody because we have {Washington} on the team," said Poulton. "He's going to break tackles and then once he gets into the open, he's going to turn the speed on. I wasn't worried about us offensively, I was worried about us trying to stop them on defense, because we had heard that they had a good offense."

But after Randy Carter (11 carries for 102 yards) scored the game's first touchdown on a 29-yard run on Oxon Hill's opening drive for a 7-0 lead, every other Clippers gain was negated by turnovers -- two inside the 20 in the second half.

"Mistakes hurt us today," said Haskins. "We knew what they were going to run, but we had missed blocks, missed coverage on the pass. You can't make those types of mistakes against a good football team, and it hurt us. The better team won today and I'm proud of my team. My players are hurt, but they'll get over it."
