Flowers (17-2); Suitland-Wise winner at Laurel (14-6); Northwestern-Crossland winner at Eleanor Roosevelt (14-6); High Point-Bowie winner at Bladensburg (15-4)

Team to beat:C.H. Flowers. The Jaguars were the most consistent team in the Prince George's 4A league, whose 12 teams constitute this region. Guard Jordan Brooks leads an efficient back court, with senior Darren Clark and sophomores Kyle Jackson and Chaune Duffy chipping in. Flowers also has one of the region's best front courts, led by forward Daniel Thompson and forward-center Jervan Wright.

Watch out for: Several teams have standout players capable of leading a strong postseason run, such as Oxon Hill's Maurice Creek; Daryl Traynham and Roscoe Davis of Wise; and Darnell Dodson of Eleanor Roosevelt. Flowers Coach George McClure said he believes Roosevelt is the region's hottest team entering the postseason. Laurel was strong early but entered this week with five losses in its past eight games, though guard Chris Tolson is capable of making a late run.

The Lions have been dominant, with only one game decided by fewer than 10 points They have a well-rounded team, with several players able to pick up the slack if one of their top players is not at his best. Forward Kwame Morgan is the Washington area's second-leading scorer, averaging 29.5 points per game. Point guard Mo Colter averages 18.7 points, and center Maurice Sutton, a 6-foot-11 inside presence, scores 12.2 points per game.

Watch out for: Fairmont Heights. The Hornets enter this week with one loss in their past nine games, a 10-point defeat at unbeaten Largo. If Kendall Durant and Keenan Perry can get going offensively and Fairmont plays good team defense, it could make a return to the state semifinals.

WCACTeam to beat: DeMatha. The Stags entered the week with one loss in conference play this season, 62-61 to Gonzaga. All-Met guard Austin Freeman and senior guard Jeff Peterson form the area's top back court. Watch out for: Just about everyone else. St. John's emerged as the league's second-best team, but there is plenty of balance, and almost no team is out of the mix. Standouts such as Bishop McNamara guard Jay Gavin, Carroll forward Kris Joseph, St. Mary's Ryken forward John Flowers and O'Connell guard Jason Clark make their teams legitimate threats.

Flowers was the Raiders' closest league game. Roosevelt has a balanced lineup, with LaKeisha Wright, Brooke Wilson and Elashier Hall all scoring in double figures.

Watch out for: C.H. Flowers. The Jaguars entered this week with 10 wins in their past 11 games. Junior forward Keyona Bryant averages 16.1 points per game, leading an experienced squad. Getting past Roosevelt, however, will be difficult.

3A South First round: DuVal (4-13) at Northern (3-13); Huntingtown (6-13) at Friendly (9-9); Chopticon (7-14) at La Plata (7-14)

Quarterfinals: DuVal-Northern winner at Largo (19-1); Westlake at Gwynn Park (14-6); Friendly-Huntingtown winner at Lackey (18-3); Chopticon-La Plata winner at Great Mills (19-2)

Watch out for: Potomac. The Wolverines struggled to find consistency, never winning more than three games in a row. But Coach Mike Strother's team has the talent to make it out of the region, led by forward Brionna Carter and guards Pryncess Tate-Dublins and Queenique Tyler.

1A South First round: W.E.B. DuBois at Samuel Banks; Marriotts Ridge at Surrattsville (12-7); Reginald Lewis at Forest Park

Quarterfinals: W.E.B DuBois-Samuel Banks winner at Dunbar-Baltimore; Forestville (1-15) at Southside; Marriotts Ridge-Surrattsville winner at Digital Harbor; Reginald Lewis-Forest Park winner at Poolesville

Team to beat: Dunbar-Baltimore. The winner of four straight state championships from 2000 to 2003, the Poets haven't won a region title since.

Watch out for: Poolesville, which lost to Dunbar in last year's region semifinal and lost in the regional final the previous two seasons. Junior guard Rachel Stream scored a career-high 24 points Feb. 9 against Seneca Valley, Poolesville's ninth victory in 11 games. Forestville, which has only one victory, earned a first-round bye and has a tough quarterfinal opponent in Southside.

WCAC Team to beat:Bishop McNamara, which had won 10 of its last 11 in the league entering this week. The Mustangs also beat No. 3 Edison in a holiday tournament and lost at No. 1 Notre Dame by seven. Watch out for: Two-time defending champion Good Counsel, slumping Holy Cross and resurgent St. John's. After sputtering early, Good Counsel won 12 of 13 league games entering this week, the only loss by three points to McNamara. Holy Cross lost to McNamara, Good Counsel and St. John's late in the season -- three teams the Tartans beat during a 12-0 start to league play. But the recent return of guard-forward Monica McNutt (Georgetown) should help the Tartans. St. John's had won nine straight, including by 18 over McNamara, until a loss to Good Counsel on Saturday.
