The St. Stephen's/St. Agnes field hockey team defeated National Cathedral, 3-1, yesterday to win the Independent School League championship at The Madeira School in McLean.

Sophomore forward Micaela O'Toole scored the game-winner with 19 minutes 56 seconds to play in the game. Junior forward Liz Barber added an insurance goal by deflecting in Jen Holden's shot in front of the net.

Holden, a senior midfielder, also had a part in the tying goal for St. Stephen's/St. Agnes when she set up senior left wing Carey Sauls.

Hilary Lambert gave National Cathedral the lead with 18:55 to play in the first half.

"They played great in the second half. We had trouble scoring in the beginning of the season, but they're peaking at the right time," St. Stephen's/St. Agnes Coach Marsha Way said. "They're a great bunch of kids to coach."

Said National Cathedral Coach Jane DeGrenier: "I was not real happy but proud of our team. They put up a great fight." . . .

With two big swings of her stick, Whitman senior midfielder Ellen O'Brien carried the Vikings to 2-0 victory over Quince Orchard the Maryland 4A field hockey semifinals at Severna Park.

"They felt pretty good when I hit them," O'Brien said. "We knew we just had to go out and keep attacking, and if we kept doing that, the goals would go in eventually."

Whitman (11-5) won its ninth consecutive game and will aim for its first state title on Monday at the University of Maryland, where the Vikings will play South River.

Wittmer Lifts Lee

Senior outside hitter Brittany Wittmer had 18 kills in Lee's 25-12, 18-25, 25-10, 25-14 regional volleyball win over visiting Mount Vernon.

"I think as a team we were all motivated. It was our first time together in regionals, so it was important we win," said Wittmer. "We work better as a team this year as opposed to last year. There's a lot more team chemistry this year."

Lee will travel to play Chantilly at 7 tonight in the second round. . . .

Langley defeated Washington-Lee in the first round of AAA Northern Region volleyball playoffs, 25-13, 25-12, 25-9, in McLean.

"It was pretty ugly win. We were the first seed going in, and they were the last seed, so it was kind of messy," Langley Coach Susan Shifflett said.

Langley will host Centreville tonight at 8.
