The Raiders blanked No. 15 Allderdice 4-0 while the Foxes squeaked past No. 14 Franklin Regional 1-0. Next up for Seneca Valley is No. 7 Peters Township. All WPIAL quarterfinal games will be played Thursday night. The Raiders and Indians will meet at 8 p.m. at North Allegheny. Fox Chapel will play No. 11 Canon-McMillan at North Allegheny at 6 p.m.
