Chantilly's Mary Casey was all over the field during last night's Virginia AAA Northern Region girls' soccer semifinal at Madison High School. The Chargers junior scored twice -- her second coming with five seconds left in the first overtime period -- to lead Chantilly to a 2-1 victory over second-ranked W.T. Woodson, knocking the defending state champion out of the playoffs.

With the victory, Chantilly (14-6) earned a trip to next week's state tournament and a date tomorrow with No. 5 Lake Braddock, a 2-0 winner over seventh-ranked Langley in the other semifinal. Tomorrow's game is a rematch of the 2003 region final, the last time both teams made the state tournament.

Casey scored her first goal a minute and a half into the game off a pass from All-Met Player of the Year Amy Smerdzinski. Casey then moved to the midfield, where she spent most of the game, while the Cavaliers did their best to push forward.

Woodson forward Claire Zimmeck tied the game with six minutes left in regulation, heading in the team's ninth corner kick off the cross from Ashley Wellner.

By that point, Casey had switched back to forward. In overtime, Smerdzinski saw Casey release behind three W.T. Woodson (13-3-2) defenders and placed a perfect ball that Casey put in the lower left corner of the net.

"When I saw that it was on her foot, I just got chills," Smerdzinski said.

After the goal, Casey moved to midfield again.

"When I'm switching around in the middle of play, it can get confusing," said Casey, who played goalkeeper last season. "But I'm happy that I can help my teammates."

Lake Braddock Rolls

The lineup shuffle continued -- and continued working -- in Lake Braddock's 2-0 victory over Langley in the other Northern Region semifinal.

After shifting players to new positions in the team's quarterfinal victory over Centreville, the Bruins again showcased their depth in shutting down the Saxons' offense and scoring two first-half goals despite playing without injured All-Met midfielder Kristin Bowers.

Sophomore Katherine Weiler played her second straight game at forward and notched the Bruins' first goal by outmuscling Langley's goalkeeper for a loose ball, dribbling around her and shooting into the open net midway through the first half.

Senior Lindsay Bowers -- Kristin's sister -- gave the Bruins (11-3-2) a two-goal margin by knocking in a free kick with just under eight minutes remaining in the half. Kristin Bowers is day-to-day after suffering a slight concussion in practice Tuesday.

"They're playing fantastic soccer," Lake Braddock Coach Liz Pike said of her team.

Langley (15-3-1) had been on a 12-game unbeaten streak.
