Francis Scott Key of Union Bridge, Md., strung together 10 straight points early in the fourth quarter yesterday to run away from Sherwood, 54-41, in Class B semifinal action of the Maryland State girls basketball tournament at Catonsville Community College.

Sherwood failed to contain Key's 6-foot-1 center Kim Duppins, who registered 22 points, grabbed 16 rebounds and rejected five Warrior shots.

Ten of Duppins' rebounds were offensive, leading to easy follow-up lay-ups. This accounted for her 10-for-16 accuracy from the floor.

"I think that we were intimidated," said Sherwood Coch Lin Gehlert. "We didn't get rolling, we didn't get our offense going, our fast break going. They outrebound us."

Key's efforts were made easier by 33 Sherwood turnovers. The Eagles gave the ball away 29 times, but only twice in the opening 4 1/2 minutes of the final period, when they took control of the game.

Leading, 36-35, with 7:11 to go, Key scored the next 10 points on three 15-foot buckets by Stacy Blankert and a pain of followups by Duppins, for a 46-35 advantage with 3:46 to play.

Sherwood couldn't pull closer than nine points after that.

Michele Muse's followup basket with 20 seconds elapsed in the second half gave Key its biggest lead to that point, 28-17. But Sherwood's pressing defense and eight points by Karen Wilson helped the Warriors close to one point, 34-33, by the third period's end. Warriors close to one point, 34-33, by the third period's end.

However, then, "They figured out how to break the press," Gehlert said. "Any press has holes in it because you double-team the ball."

Wilson led Sherwood with 16 points.

Both teams are 17-3.
