AAA Nondistrict

No. 18 Oakton at Annandale

Tonight, 7:30

Outlook: Three games into Annandale's district campaign, Atoms Coach Dick Adams said his team couldn't be compared with the powers in the Concorde District. Four weeks later, he has the first chance to find out. Annandale (7-2), riding a seven-game winning streak and having clinched its first playoff berth in 11 years, will host one of the three postseason-bound Concorde teams, Oakton (7-2), in a game that will determine seeding in the Division 6 Northern Region playoffs.

AAA Liberty

Marshall at Madison

Tonight, 7:30

Outlook: Playing must-win games for the past three weeks, Madison has responded by outscoring its opponents, 94-17. The Warhawks (6-3, 5-1 AAA Liberty District) will make their fourth Division 5 Northern Region playoffs in five seasons with a victory. Marshall (5-4, 2-4) could play spoiler and equal its win total from the past four years combined with a win.

AA Dulles

Heritage at

Loudoun County

Tonight, 7:30 p.m.

Outlook: Heritage (6-3) has already secured its first winning season in the school's four-year history. A victory over Loudoun County (4-5) would also give the Pride at least a share of the AA Dulles District title and keep its playoff hopes alive. But beating the Raiders would mean avenging a 27-19 loss to Loudoun County on Sept. 30. Both teams totaled exactly 335 yards of offense in that game.

WCAC Semifinals

St. John's at Good Counsel

Tonight, 7

Gonzaga vs. DeMatha

Tomorrow, 1:30 p.m. at Parkdale High

The No. 19 Falcons (7-3) have to put their disheartening 22-21 loss to DeMatha last week behind them. Coach Bob Milloy believes his team is ready to move on after watching his preparations for tonight's WCAC semifinal against St. John's (6-4). "We have a whole new season," Milloy said. "It was a bitter pill, a tough loss, but if we dwell on it we're going to get beat again." Good Counsel won the team's regular season meeting, 35-0, on Sept. 23; St John's enters with a four-game winning streak. In the other semifinal, expect the third-ranked Stags (9-1) to give running back Patrick Mealy plenty of carries tomorrow against Gonzaga (6-4). In the teams' first meeting, a 34-7 DeMatha win, Mealy scored all five touchdowns.
