With the final slate of district games scheduled today, two of the four automatic berths to the Northern Region Tournament haven't been claimed.

Madison and Edison have clinched Liberty and National regular season district titles, respectively, giving them No. 1 seeds in their tournaments.

Meanwhile, the regular season crowns in the Concorde and Patriot districts are still being contested. Here is a glance at the races in each district:

CONCORDE

Centreville leads Chantilly by a half game and Oakton by a game and a half in the district standings. The Wildcats (12-4, 8-3) clinch the No. 1 seed with a road win over South Lakes today. Chantilly, which hosts Oakton today, takes the top seed with a win and a Centreville loss.

The Cougars (10-7, 7-4) will earn no lower than the third seed. Oakton can snatch the No. 1 seed with a win over Chantilly and a Centreville loss.

A Herndon (6-11-1, 5-5-1) win at Jefferson gives the Hornets the No. 4 seed, while a Herndon loss makes Westfield (9-7, 6-6) the fourth seed.

South Lakes (6-8, 3-8) will be the No. 6 seed, and Jefferson (2-9 in the district) is the seventh seed. The Concorde District Tournament starts Wednesday at the site of the higher seeds. South Lakes hosts the semifinals on May 17 and the final on May 20.

PATRIOT

If both Robinson and Lake Braddock win today, the No. 1 seed out of the Patriot District will be decided by a coin flip. The Bruins (13-4, 10-1) host T.C. Williams, which hasn't won a district game this season. The Rams (12-1, 10-1) travel to West Springfield.

Hayfield (13-6, 8-4) has locked down the third seed, and West Springfield (8-9, 5-6) is guaranteed the fourth seed.

Annandale (5-12, 4-7), by virtue of its 6-0 win over visiting West Potomac last night, earns the No. 5 seed and plays the Spartans in a Patriot District Tournament first-round game. The tournament begins on May 18, and all games are being played at West Springfield.

LIBERTY

A few Liberty District teams have scheduled non-district games for today and Monday, but the district tournament seeds have already been determined.

Top seed Madison (17-1, 11-1) enjoys a first-round bye in the tournament, which starts Wednesday at the sites of the higher seeds. The Warhawks host the semifinals on May 17 and the final on May 20.

Second-seeded Langley (15-4, 9-3) takes on No. 7 seed Marshall (3-11-1, 1-10-1), No. 3 Woodson (10-6, 7-5) plays No. 6 Fairfax, and No. 5 McLean (8-10, 6-6) draws No. 6 Lee (7-10-1, 5-6-1).

NATIONAL

Everything except the third and fourth seeds have been determined in the National District.

Edison (11-3, 10-1) enjoys a first-round bye in the National District Tournament, which kicks off Wednesday at the site of the higher seed. Falls Church hosts the semifinals on May 17 and the final on May 20. The Eagles host Yorktown in their final regular season game today.

Mount Vernon (9-8, 8-3) takes on Washington-Lee (6-6, 5-6) - the No. 5 seed in the district tournament - in a regular-season game today. The Majors have already nailed down the No. 2 seed and play winless Stuart in a first-round tournament game Wednesday.

Wakefield (7-8, 6-5) would clinch the third seed today with a win over Falls Church or a Yorktown loss. If either happens, the Warriors play the Jaguars - the No. 6 seed - again in a first-round tournament game.

Yorktown (6-7, 6-5) needs a win over Edison and a Wakefield loss to grab the No. 3 seed. The Patriots would open the district tournament against Falls Church if that happens. A Yorktown loss or a Wakefield win means the Patriots play Washington-Lee in a first-round tournament game.
