Football action intensified last weekend as teams began to look ahead and jockey for playoff positions. T.C. Williams and Marshall continue to look like the dominant teams in the Northern Region while Wakefield continues to contend for the Potomac District title. In golf, Chantilly and Lee took the Potomac and Gunston district titles, respectively. Chantilly held off Fairfax despite a hole-in-one by the Rebels' Chip Bolger. Football

T.C. Williams began its quest for a sixth consecutive Northern District title with a 35-14 victory over Lake Braddock. It was the 23rd straight district win for the Titans, who are unbeaten in district play (24-0-2) in Coach Glenn Furman's five-plus seasons. Lydell Scott took over the Northern Region rushing leadership by gaining 203 yards and scoring four touchdowns. Lake Braddock became the first team to score against the Titans' defense this year.

Defending Northern Region champion Marshall continued to roll, crushing Herndon, 42-7. Quarterback Lonnie Goldberg threw for two touchdowns and ran for another as the Statesmen improved to 5-0. On its way to the 1986 state championship game, Marshall defeated T.C. Williams. That won't happen again because the two teams cannot meet in the playoffs. The new Virginia High School League playoff system, based on enrollment figures, has T.C. Williams in Division VI and Marshall in Division V.

The new playoff format gives new hope for several teams, particularly in the Northern District, which has been so dominated by T.C. Williams. Robinson bettered its record to 4-1 with a 16-14 victory over Oakton. The Rams, who play T.C. Williams next Saturday, got 91 yards rushing from Mike Johnson and a touchdown pass from Brent Torgeson to Pete Zophy.

W.T. Woodson, which hosts T.C. Williams tomorrow, blanked West Springfield, 20-0, raising its record to 4-1. Woodson's defense continues to excell holding the Spartans to only 13 total yards. It will need another solid effort tomorrow if it hopes to defeat T.C. Williams.

The Potomac District race is shaping up to be a wild one. Chantilly and Wakefield are 2-0 in the district, with Annandale and Fairfax just behind at 1-0. Wakefield won its fifth straight after a season-opening loss to Yorktown, defeating Stuart, 41-35. Quarterback Randy Lyon and wide receiver Rodney Hunter hooked up on three scoring passes to offset the three touchdown passes Stuart quarterback Darnell White threw to Chris Recabo.

Annandale got two touchdowns from running back Julio Lacayo as the Atoms' defense recorded its second straight shutout, 31-0, over Mount Vernon. Chantilly routed Falls Church, 34-7, to keep pace with Wakefield.

In the Great Falls District, Madison kept pace with Marshall at 3-0, parlaying a strong running game with a stout defense to defeat Yorktown, 17-7. B.J. Runyon's 121 yards led the rushing offense and the defense held Yorktown in check in the second half. John Flynn's 29-yard field goal in the second half broke a 7-7 tie before Runyon clinched it with a three-yard touchdown run with 50 seconds to play.

South Lakes, which previously lost to Marshall, remained one game behind the leaders with a 32-12 victory over Langley.

Lee and West Potomac took the early lead in the Gunston District. Lee more than doubled its season's scoring output in handing Edison its third straight setback, 24-15. The Northern Region's leading receiver, Brian Kriz, caught six passes for the Lancers. West Potomac had 322 yards rushing and blanked Hayfield, 36-0.

Golf

Medalist Blair Thomas' three-over par 76 led Chantilly to a victory in the Potomac District tournament last week at Twin Lakes. The Chargers, 10-0 in dual matches, also placed Bruce Winesett (81) and Scott O'Brien (86) in the top 10. Bolger aced the 192-yard 17th hole on his way to a round of 87. The Chargers, who finished with a score of 329 and Fairfax (336) advanced to the regional tournament (played Tuesday) along with Tom Miller of Falls Church, Bruce Cathell and Derek Jones of Annandale and Mike Guhl and Brian Harris of Jefferson.

Lee successfully defended the Gunston District tournament title with a two-day score of 635 at Woodlawn and Fort Belvoir Country Clubs. Steve Clary of Mount Vernon was the leading medalist with a 157 total for 36 holes. Lee, which is 10-0 in dual meets and finished second in the Quantico and Herndon Invitationals, took the next four places on the way to a 66-stroke win over West Potomac. Jeff Jividen and Mike Bouselaire each shot 159's for the winners while Jamie Dezzutti and T.J. Beitelman followed close behind with 160 and 162 respectively.

Mark McGuire and John Benton placed second and third to lead Madison to the Great Falls District title while Oakton's Brian Quackenbush took medalist honors as the Cougars won the Northern District tournament.

Cross Country

Herndon and W.T. Woodson took advantage of Lake Braddock's absence from the William & Mary Invitational to win team titles in the A Race. Herndon's boys were led by Todd Cerino's third-place finish and Steve Donahue's fifth, and beat Gonzaga (D.C.), 76-116. South Lakes' Anne Evans won the girls A Race in 18:39, but a third from Melissa Stewart and a ninth from Kristen Halizan enabled W.T. Woodson to beat Woodbridge for the team crown.

Herndon's girls, led by a seventh place finish by Celeste Kisielewski, edged Whitman (Md.) for the B Race team title. Fairfax placed four runners in the top ten to easily win the girls C Race. Kristy Walker finished second, Jonelle Thomas fifth, Nancy Seymour eighth and Abby Nern ninth.
