Three teams that played in the WPIAL boys volleyball finals last year will return this season after victories Tuesday night in the semifinals.
In Class AAA, top-seeded North Allegheny earned a seventh consecutive berth in the title game and its 14th in the past 16 years with a 25-21, 25-14, 25-13 sweep of No. 4 seed Penn-Trafford. The Tigers have won six consecutive WPIAL titles.
Bethel Park, the No. 3 seed, claimed its second Class AAA title berth, but first since 2008, with a 25-21, 25-18, 25-23 upset of No. 2 seed Norwin. The loss ended Norwin's hopes of making a return trip to the final.
In Class AA, Ambridge and Derry set up a championship rematch with semifinal victories at North Allegheny High School.
Top-seeded and defending champion Ambridge, earned its seventh title berth in the past 10 seasons with a 25-13, 25-20, 25-17 sweep of No. 4 seed Beaver County Christian.
Derry, the No. 2 seed, earned its ninth WPIAL title berth and third in the past four years with a 25-12, 25-23, 25-13 sweep of No. 6 seed Our Lady of the Sacred Heart. Josh Wannamaker led Derry with 13 kills, while Matt Vasinko and Nick McNutt added 10 kills each.
"Making it back to the WPIAL title match is one of the goals we set, so we can cross that off our list," Derry coach Shawn Spencer said. "The kids are really looking forward to the opportunity of playing in the title match again."
The title match and consolation final in each class will be Thursday at Baldwin High School. Ambridge will face Derry in the Class AA final at 6 p.m., followed by the Class AAA final between North Allegheny and Bethel Park at 8 p.m.
The two consolation matches will be in Baldwin's second gym.
Penn-Trafford will face Bethel Park in Class AAA at 6 p.m. Beaver County Christian will face OLSH in Class AA at 8 p.m. The top three teams in each class qualify for the PIAA championships, with first-round action on May 29.
