Lake Braddock's boys and girls teams successfully defended their Virginia AAA Northern Region track titles yesterday at George Mason University. The top six finishers in each event advanced to next week's AAA state meet, which will also be held at GMU.

The Bruins girls scored in 11 of 13 events for a total of 112 points. South Lakes, led by double winners Kendyl Baugh and Anne Evans, finished second with 44 points, one ahead of T.C. Williams.

The Bruins were led by Angela Griffith, who won the long jump, and Caroline McCormick, who captured the 55-meter hurdles. Lake Braddock's girls also won the 800- and 1,600-meter relays.

In all, the Bruins girls have won seven regional titles since competition began in 1980.

Lake Braddock's boys also dominated, scoring 122 points. T.C. Williams, led by Anthony Boyd, who won both the 55 and the 300, finished a distant second.

David Smith scored victories in the 1,600 and 3,200 to lead the Bruins. Allen Johnson was another double winner for Lake Braddock, capturing the long jump and triple jump. The Bruins won both relays, and Brad Baker (1,000) and Richard Cariens (500) also took firsts.

South Lakes' girls team was led by Baugh, who is the defending state champion in both the 300 and 500. The Seahawks' junior participated just three times this year because of an abdominal injury.

Evans won the regional cross country meet in the fall and was second in the 3,200 last year in the state meet.

She ran totally different races to win the 1,600 and the 3,200 yesterday. In the 1,600, the senior needed a late rush to edge Lake Braddock's Kim Desmond. But in the 3,200, she led wire to wire, running away from the pack in the stretch.

Virginia State Gymnastics:

North Stafford won the AAA title at Cox High School in Virginia Beach, finishing with 107.65 points to edge West Springfield with 107.30. Defending champion Lake Braddock was third.
