Field hockey and boys' and girls' soccer teams begin play today in region tournaments that are the first step to awarding state championships.

The four teams -- or five in case of a tie -- with the highest winning percentage were seeded by record, with the rest of the matchups selected randomly. And this season for the first time, the highest seed hosts each game.

"Now, the regular season means something, and if you do well, you get rewarded," said Centennial girls' soccer coach Mike Senisi, whose team is the top seed in the 3A East Region tournament. "You have earned the chance to play at home." The following are schedules for Howard County teams.

FIELD HOCKEY

Quarterfinals, today

3A East: Centennial at River Hill, 3:30; Annapolis at Long Reach, 3:30; Wilde Lake at Mount Hebron, 3:30.

2A South: Reservoir at Howard, 3:30; Atholton at Hammond, 3:30; Southern at Glenelg, 3:30.

1A North: Oakland Mills at Perryville, 3:30.

Future rounds: Region semifinals, Tuesday; region final, next Thursday; state semifinals, Nov. 8 and 10; state finals, Nov. 15-16 at University of Maryland.

Best draw: Mount Hebron. The second-seeded Vikings (11-2) defeated Wilde Lake (2-10) and Long Reach (8-2-3) during the regular season, and Annapolis has a losing record. The Vikings won't meet top-seeded Severna Park (15-0), which Mount Hebron Coach Jeanette Ireland considers the tournament favorite, unless both teams reach the final.

Worst draw: Centennial. The Eagles (9-4-1) play at River Hill, and they could face defending 3A state champion Severna Park. If they advance, the Eagles would likely play on the road in the region final.

Best chance of advancing to state tournament: Glenelg. The defending 2A South Region champions have three players who have scored at least nine goals -- led by senior Terri Coover's 12.

BOYS' SOCCER

Quarterfinals, Monday

3A East: Douglass-Long Reach winner at Bladensburg, 3:30; Surrattsville at Centennial, 5; Gwynn Park at Mount Hebron, 5; Wilde Lake at River Hill, 5.

2A South: Southern-Atholton winner at Hammond, 7; Reservoir at Glenelg, 5; Howard at DuVal, 3:30.

1A South: Oakland Mills at Brunswick, 3:30.

Future rounds: Region semifinals, Nov. 5-6; region final, Nov. 9-10; state semifinals, Nov. 12-13 at UMBC; state finals, Nov. 18-20 at UMBC.

Best draw: Centennial (5-5-3). The 3A East Region's fourth seed won't have to play River Hill (10-1), Mount Hebron (11-1-1) or Wilde Lake (5-5-2) before the region final. Centennial's top-half of the bracket includes Douglass and Long Reach -- both of whom have losing records -- and undefeated Bladensburg, which has never won a region title.

Worst draw: Mount Hebron. Should the third-seeded Vikings get past Gwynn Park, they could have to travel to play at two-time defending state champion River Hill.

Best chance of advancing to the state tournament: Hammond, which entered the week having won four of its past five games.

GIRLS' SOCCER

Quarterfinals, Monday

3A East: Wilde Lake at Mount Hebron, 7; Long Reach at River Hill, 7.

2A South: Central at Glenelg, 7; Howard at Atholton, 7; Hammond at Reservoir, 7.

1A South: Digital Harbor at Oakland Mills, 7.

Future rounds: Region semifinals, Nov. 5-6; region final, Nov. 9-10; state semifinals, Nov. 12-13 at UMBC; state finals, Nov. 18-20 at UMBC.

Best draw: Reservoir, which opens against Hammond, a team it defeated during the regular season. If the Gators win, they would host Southern or Calvert. Reservoir would play defending region champion Glenelg (8-3-2), which beat them, 1-0, during the regular season, only if both teams advance to the region final.

Worst draw: Mount Hebron (8-4), which hosts Wilde Lake (5-4) and, with a victory, would travel to face Centennial (8-1-1), which will be well rested after receiving a bye in the first two rounds.

Best chance of advancing to state tournament: Glenelg. The topseed in the 2A South Region team went 4-0 against the four Howard County teams in the region, and the remaining teams each finished with a losing record.

Note: The Maryland Public Secondary Schools Athletic Association will hold its draw for the region volleyball tournament Monday, with play beginning Nov. 5.
