Freeport was the only team to claim a second straight WPIAL title.
It was the fourth title in seven years for Freeport and featured an incredible comeback in the first set. With Beaver leading 24-18 and needing only one point to close out the set, Freeport scored 10 consecutive points to pull out a 26-24 victory.
"Many of our girls played in last year's championship match, so they knew what to expect," Freeport coach Tom Phillips said. "When we fell behind in the first set, the girls didn't panic."
Beaver rebounded to win the second set 25-18, but Freeport claimed the next two sets, 25-19 and 25-20, thus claiming a second straight title. The Yellow Jackets were led by Katie Zingaro, who had nine kills.
"This title means more to me since it's my senior year," said Freeport outside hitter Maddie Christy, who recorded seven kills.
Freeport's season came to an end in the opening round of the PIAA Tournament when the Yellow Jackets dropped a 3-1 decision to North East.
In Class 4A, Seneca Valley claimed its second title and first since 2011 by sweeping Baldwin in straight sets, 27-25, 25-22, 25-21. Baldwin had won the past two titles.
"It's exactly five years since our first title," Seneca Valley coach Karen Martini said. "We won on Nov. 5, 2011. I'm so proud of my girls."
The key to Seneca Valley's win was its balance. Opposite Emily Devlin led the Raiders with 14 kills, while middle hitter Maria Alfano contributed 13, and outside hitter Tatum Poirier had 11.
"Our balance has played a big part in our success," Martini said. "Our passing and defense were also strong."
