Virginia 5A North region semifinal

No. 18 Broad Run at No. 4 Briar Woods

Friday, 7 p.m.

At stake: A berth in the 5A North region final

Watch for: Briar Woods quarterback Trace McSorley and a talented receiving core. McSorley (Vanderbilt) has thrown for over 2,400 yards and added 675 on the ground and boasts a sterling 53-4 career record as the four-year starter for the Falcons (11-1). Speedy wide receiver Brandon Polk is coming off his best game of the season (seven catches, 130 yards, TD) in a 49-7 win over Mountain View. Broad Run is led by junior quarterback Brady Reitzel who scored the game-winning touchdown in last week’s win over rival Stone Bridge. Reitzel has thrown for 1,500 yards and 12 touchdown for the Spartans (9-3) who are looking to return to the state semifinal round for the first time since they won consecutive AA Division 4 titles in 2008 and 2009.

Skinny: The Ashburn rivals met Oct. 18, with Briar Woods winning in a 34-0 rout. Broad Run is looking for its first regional final berth since 2010, when the Spartans fell to Briar Woods 24-21 in the Virginia AA Region II Division 4 semifinal in Coach Matt Griffis’s first year at the helm. Briar Woods has won three consecutive state championships under Coach Charlie Pierce and is 17-0 in the postseason over the last four seasons.

Briar Woods quarterback Trace McSorley has never lost a playoff game in his four-year career. He’ll try to lead the Falcons back to the state semifinals with a win over Broad Run on Friday in Ashburn. (John McDonnell/The Washington Post)
