It's been a goal all season for the Knoch girls volleyball team.

Reach the WPIAL final.

It's been a destination that has eluded the Knights in the past.

No longer.

Sarah Armahizer had 12 kills and Knoch dominated Thomas Jefferson with a 25-14, 25-13, 25-20 sweep in the WPIAL 3A semifinals Thursday night.

“I felt like we played really well,” said Knoch coach Diane Geist. “There's always room for improvement. We didn't make a lot of errors and we hit well.”

Hannah Rowe and Kennedy Christy each added eight kills and Abby Pospisil had 17 service points for the Knights (19-0).

Knoch has only made the WPIAL final one other time, in 2003, losing to Hopewell in the Class AA championship.

This year, the No. 1 seeded Knights will get No. 2 Montour in the title match Saturday at Baldwin High School.

The time of the match is still to be determined.

Montour swept West Allegheny Thursday night.

Both Knoch and Montour are guaranteed a spot in the PIAA 3A playoffs, which begin next week.

“It means a lot. It feels good,” Geist said. “It's a goal we've been working toward all season.

“It's one more step,” Geist said. “We still have a lot of work to do.”
