W.T. Woodson swept the Virginia AAA Northern Region lacrosse championships last night behind a converted defender's three goals for the girls team and the boys' dominant fourth-quarter performance.

Junior Jill Marvin -- moved from defense to attack a year ago -- scored a game-high three goals to lead the fourth-ranked Cavaliers to a 9-7 victory over No. 9 Lake Braddock. In the second game of the doubleheader at Lee High School, W.T. Woodson's boys held No. 10 Centreville to one shot in the final quarter for a 9-6 victory.

Woodson's girls (17-0) will host the unofficial state title game against the Northwestern Region champion June 5. The Woodson boys (14-3) will play the Northwestern Region champion, also next Saturday at Woodson. Times are not yet determined.

Woodson girls coach Darah Bonham moved Marvin to attack before last season's regional tournament because he said Marvin was talking too much on the field and not concentrating.

"She was being too much of a gossip-queen," Bonham said. "I thought she was capable of a lot more, so we asked her to do more."

Marvin responded with the game-winning goal in a semifinal victory over Herndon in last year's tournament. In this year's regional tournament, she had six combined goals in the semifinals and final and currently is third on the team with 26 goals.

"Before last year's region tournament, Coach Bonham pulled me aside and really kicked my butt verbally," Marvin said. "I liked to goof off during games and really just wanted to have fun. But [Bonham] really opened my eyes to the potential I had in this sport, and this year has been a lot of fun."

In the second half last night, the Cavaliers scored on their first three shots -- from senior Barbie Kersten, sophomore Johanna Buchholtz and Marvin -- to take a 7-3 lead with 16 minutes 25 seconds remaining. Lake Braddock (16-1) was led by All-Met midfielder Shannon Jarrett, who had three goals.

In the boys game, Woodson held Centreville (13-3) to one shot on goal in the final quarter while controlling the ball for nearly 10 minutes in the 12-minute quarter. The Cavaliers were led by two goals each from sophomore Greg DiCerbo, junior Brent Renner and senior J.P. Royal.

Junior attackman Nick Purkat added a goal and four assists, extending his school-record for assists in a season to 59. Purkat broke the record of 44 he set as a sophomore.
