Yorktown’s Audrey Denkler didn’t remember much about her goal that opened the scoring Monday against Stuart. She remembered the ball coming in from the corner and landing on her left foot, thinking “there’s the goal and the window,” then hitting it. It all happened very fast.

The fifth-minute score, which Denkler sent to the right side of the net off a feed from Olivia Tripodi, set the tone for a stellar offensive performance by Yorktown, which beat Stuart, 3-1, in a Virginia nonconference girls’ soccer game in Falls Church.

“I was like, ‘Yay,’ ” Denkler said. “And it was my bad foot, and it didn’t hurt, and I was like, ‘Success.’ ”

Yorktown (9-0-3) is unbeaten against Stuart over the past eight years — with the closest game before Monday a 2-0 win for the Patriots in 2010. During that stretch, No. 6 Yorktown has outscored its former AAA National District rivals, 46-4, and has not allowed the Raiders to score more than one goal in any of those matches.

This season, the Patriots have outscored their opponents 35-5 over their past nine games, including Monday night’s contest, and are 8 -0-1 this season against teams outside Conference 6.

“We don’t think about it as conference, nonconference, [or] we have to beat this team and beat this team,” Denkler said. “I think every time we get on the field, we’re like, ‘We need to play our game. We need to beat whoever it is we’re playing against.’ ”

Marisa Fitz scored the game-winner for the Patriots early in the second half and later added a security goal in the 58th minute. Her first goal came in the 46th, when she lined up for a kick at the corner of the box and sent it top shelf to put Yorktown up, 2-1.

Fitz’s second goal was a low ball that rolled past the goalie.

“That’s the goal — the goal is to score,” Fitz said. “My teammates were setting me up with good balls, and they just got in the back of the net.”

Yorktown and Stuart (7-2-1) were tied at the end of the first half. Yorktown’s offense controlled the ball for much of the half, recording 12 shots on goal, four corners and forcing the Raiders’ goalie into six saves, but they didn’t break through again in the first 40 minutes.

Stuart’s lone goal came in the 13th minute out of a corner set. After the ball bounced off a teammate and redirected off the grass, Mariana Hershner got behind the defense on the left side for a header that floated over the hand of the goalie for the equalizer.

“[The] grass is a little uneven . . . and the ball bounces in ways that are unexpected,” Yorktown Coach Mariano Alonso said. “I think it was a little field trick.”
