ADAMS TWP — Emily Wagner knew to just hang out by the net.

Her teammates did the rest.

The Seneca Valley senior forward scored a pair of goals a minute and 41 seconds apart early in the first half Wednesday night. The tallies led the top-seeded Raiders to a 3-0 WPIAL Class AAA girls soccer quarterfinal victory over Fox Chapel at the Mars Athletic Conference.

Wagner had scored only two goals this season. Four teammates with 10 or more goals this year — Kelsey O'Connor, Cassidy Testa, Sarah Anderson and Emily Cekella — did not score on this night.

“We don't care who scores,” Wagner said. “Our style of play is to crush the net and someone's going to knock it in.

“It's a goal for the team no matter whose foot it comes off of.”

Seneca Valley (20-0) will take on Penn-Trafford — a 2-1 winner over Upper St. Clair — in the semifinals Monday at a site and time to be determined.

“Our play was a little sloppy and choppy in the second half tonight,” Raiders coach Dave Sylvester said. “We were going through the motions a little bit.

“But our goal tonight was to score early, get a lead and put this one away in the first half. We're in the semifinals. That's what's important.”

Wagner scored her first goal at the 27:40 mark of the first half. Megan Majeski slid a quick pass over to Alicia Hart on a direct kick from 25 yards out. Hart's shot was deflected away, but rebounded to Wagner, who was stationed to the right of the net.

Wagner tucked the shot inside the left goalpost to put SV in front.

Her second goal came from approximately the same spot moments later. O'Connor forced her way through two defenders down the middle before the ball came to a wide-open Wagner.

“You can't give up early goals to that team,” Fox Chapel coach Peter Torres said. “It just motivates them that much more.”

Torres would know. The Foxes (15-3-2) have allowed 11 goals all season. Seven of them were scored by Seneca Valley. The Raiders defeated Fox Chapel, 4-0, less than two weeks ago.

“They just keep moving forward,” Torres said. “They are a very aggressive team.”

Majeski, the Raiders' team leader with 14 assists, put SV ahead 3-0 when she rifled a shot high into the net from 30 yards out with 13:26 left in the opening half. It was her fifth goal of the campaign.

Seneca Valley registered seven of its nine shots on goal during the first 40 minutes. The Raiders had four corner kicks in the second half, but failed to add to their lead.

“The second half was all about protecting our lead,” Wagner said. “We dropped another player back and just wanted to keep the ball out of our own net.”

Senior goalkeeper Jessica Beil saw to that, twice stonewalling 20-goal scorer Taylor Cohen in the goal crease midway through the second half. Fox Chapel managed only four shots on goal for the night.

The first two were long-range efforts in the first half.

“Jess is a four-year starter for us back there and she turns her game up a notch at playoff time,” Sylvester said. “We need her.

“They started running at us pretty good there, so we went into more of a defensive posture in the last 20 or 22 minutes.”

Torres, whose Fox Chapel team has only one senior starter, lauded his team's effort.

“Our girls worked their tails off in the second half,” he said. “We generated some good chances. We just couldn't put it in.”

Seneca Valley has outscored its opponents 93-6 this season.
