South Lakes used a stifling man-to-man defense and 21 points from forward Terri Bradley to hand 19th-ranked McLean a 52-42 defeat last night in a Virginia AAA Great Falls District girls basketball game at McLean.

South Lakes (9-4, 7-0) ran its winning streak to six games with the victory. McLean (10-4, 6-2) lost for the first time in nine games and slipped two games behind the district-leading Seahawks.

McLean came into the game yielding 37 points a game but was on the receiving end of defensive pressure and trailed, 30-12, at halftime. The Highlanders were forced out of their offense early and needed a late rush in the fourth quarter to finish with 17 field goals in 49 attempts.

"Our defense did a good job of denying the pass to the posts," South Lakes Coach Jill English said. "We looked to front them inside and it frustrated them."

Bradley had her sixth straight solid game, although she made only seven of 20 field goals. She has averaged 21 points during the team's winning streak. But she finished with nine rebounds and six steals. Fourteen of her points came in the second quarter when South Lakes turned an 11-8 lead to the 18-point halftime advantage.

South Lakes' aggressive defense forced the Highlanders out of their offense in the first half and they made only five of 31 shots. Bradley took charge early in the second quarter and made seven of eight free throws once the Seahawks made it into the one-and-one bonus. As important as her contribution on offense were her four defensive rebounds and three steals in the second quarter.

McLean's Kristin Miller (14 points) scored to draw the Highlanders to 17-11. But Bradley made three free throws and three field goals (one a three-pointer) during a 13-1 spurt in the last 4:37 of the first half.

Bradley struggled early, missing three of her first four shots, but the Seahawks took an 11-6 lead. McLean failed to take advantage, missing its first nine shots and committing three turnovers. Seahawks forwards Carla Casey and Nancy Judd led the defense with four blocked shots in the first period.
