Most of the Maryland high school soccer teams still alive in the postseason moved up their region semifinals and finals to Monday to avoid the Election Day business around the region. Here's a rundown of the action as several boys' and girls' teams punched their tickets to the state semifinal round.

BOYS

4A East region final: Severna Park 1, Leonardtown 0

Severna Park defeated Southern Maryland Athletic Conference champion Leonardtown, which entered the Maryland 4A East region final with a 15-0 record. After an impressive defensive performance, senior Scott Huntley scored in the final minutes to send the Falcons to their first state semifinal since they won their third state title in 2013.

In the region semifinals Severna Park faced 2015 state finalist Meade, who defeated the Falcons 2-0 in the Anne Arundel County championship game. Behind nine saves from junior Sam Farrell, the Falcons advanced with a 2-0 win. Junior Andrew Belloff converted a penalty in the first half, and Severna Park (15-2-1) held off heaps of pressure before Huntley iced the game in stoppage time.

4A North region final: Bel Air 1, Sherwood 1 (Bel Air advances 5-4 on penalty kicks)

Sherwood shut out Paint Branch, Mergenthaler Vocational and Howard to advance to the 4A North region final. After regulation and overtime finished tied 1-1, the Warriors fell in penalty kicks.

Severna Park will face Bel Air on Saturday at Wise. The Falcons won 3-1 when the teams met on Sept. 8.

4A West region semifinal: Northwest 2, Quince Orchard 1

Northwest topped No. 1 seed Quince Orchard for the second time this season to earn a spot in Wednesday's region title game at Wootton.

4A West region semifinal: Walter Johnson 2, Whitman 1

Walter Johnson beat Bethesda rival Whitman for the second time this season on Monday.

Northwest (11-4) will face Walter Johnson (14-1) on Wednesday in the 4A West final at 5:15 p.m. at Wootton, and Mark Giannatto (@mgiannotto) will be there to cover it.

4A South region semifinal: Eleanor Roosevelt 2, Bowie 2 (Eleanor Roosevelt advances 4-2 on penalty kicks)

Defending region champion Eleanor Roosevelt advanced to the 4A South region final thanks a pair of saves by goalkeeper Jonathan Middour in a penalty shootout win over Bowie. The Raiders (9-2-2) will meet Northwestern (8-1-5) Wednesday at Wise at 5 p.m. with a berth in Saturday's state semifinals on the line.

3A South region final: Watkins Mill 3, Northern 0

Watkins Mill avenged a regular-season loss to Blake before shutting out Magruder and Northern to win the 3A South region. The Wolverines (14-1) will face 3A West champion Urbana in the state semifinals on Saturday at Linganore.

3A East region final: Mount Hebron 3, Chesapeake 1

Mount Hebron topped Howard County Rivals rivals Glenelg and Centennial to advance to Monday's 3A East region final against Chesapeake. Jacob Parrott scored off a free kick from midfield to give the Vikings a 1-0 lead at halftime before Sebastian Tobar and Johnny Linsenmeyer added to the lead after the break. The victory gave the Vikings their first region title since 2011.

Mount Hebron will face either Lansdowne or Towson on Saturday at Linganore in the 3A semifinals.

2A South region final: La Plata 1, Southern 0

La Plata (15-4) is trying to return to the state title game, where it fell to Middletown last year. The Warriors will face either Middletown or South Carroll in this weekend's state semifinals at River Hill.

GIRLS

4A East region final: South River 2, Arundel 1

Freshman Riley Dillahay scored both goals as the Seahawks continued their surge through the postseason by winning the Maryland 4A East region title for the third time in four years. South River also beat defending Maryland 4A state champion Broadneck, 4-1, in the region semifinals. It will face the winner of Tuesday's 4A North region final between Blair and Perry Hall on Saturday at Wise.

3A South region final: Centennial 4, Westminster 0

Senior Jasmine McCree and sophomore McKenna Griffin combined to score three goals in the opening 10 minutes of play to lead the Eagles to the Maryland 3A South title and their first state semifinals appearance since 2004. Centennial is scheduled to play again Saturday at Linganore against perennial Frederick County powerhouse Urbana, which defeated Blake, 4-0, in Monday's 3A West region championship game.

2A North region final: River Hill 5, Hereford 2

After a one-year hiatus, the Hawks are back in the state semifinals thanks to two early goals by junior captain Megan Chun which set the stage for a convincing victory. The Hawks won three straight Maryland 3A state championships between 2012 and 2014 before bowing out in the first round of the 2A playoffs a year ago. They will get to play at home in the 2A state semifinals, which were already scheduled to be held at River Hill this season. The Hawks will face the winner of Tuesday night's 2A East region final between defending state champion Fallston and Queen Anne's.
