The York-Adams League will have a District 3-AA girls' volleyball champion.
And two area teams will compete in the PIAA Class AA state playoffs.
That much was determined on Thursday night at Wilson High School.
The York-Adams girls flexed their volleyball muscles in West Lawn, earning a pair of District 3-AA semifinal triumphs.
The York Suburban girls earned a stirring 18-25, 19-25, 25-23, 25-20, 15-10 come-from-behind victory over previously unbeaten Palmyra.
Delone Catholic, meanwhile, had a much easier time in downing Berks Catholic, 25-13, 25-21, 25-23.
Suburban and Delone will now meet for the District 3-AA championship back in York County. The title showdown is set for 5 p.m. Saturday at Dallastown High School.
The Squirettes and Trojans did not meet in the regular season. Delone won the York-Adams Division III and York-Adams Tournament championships, while Suburban finished second in York-Adams Division II.
Suburban's triumph over Palmyra had to be considered an upset. The Cougars entered the match at 21-0 after rolling to the Mid-Penn Conference Colonial crown. They were ranked No. 2 in the final District 3-AA power ratings, just behind Delone and just ahead of Suburban.
The Trojans (14-3) received contributions from a variety of players. Emily Miller produced 22 assists, while Kayla Gibbs added 18 digs and 15 kills. Maura Brehl contributed 13 kills and 10 digs. Mikala McBride (13 assists) and Morgan Lehman (10 kills) also did their fair share.
In the fifth-and-deciding game, the Trojans rallied from an 8-5 hole to complete the dramatic comeback. And in the third game, Suburban rallied from a 17-10 deficit to begin its comeback.
Now Suburban will have to contend with a Delone program which is quite familiar with the big stage. The Squirettes are the defending District 3-AA champions and they advanced all the way to the PIAA Class AA state finals a year ago. They handed Berks Catholic, which was No. 4 in the final District 3-AA power ratings, its only two losses of the season -- both sweeps.
Delone improved to 23-0, while Berks Catholic fell to 17-2. Cambria Wierman had 13 kills for Delone, while Maddie Comley added eight kills.
Overall, Delone has won nine District 3-AA titles in its history. Suburban, meanwhile, will be looking for its first district crown since 1976, when they won the second of its back-to-back District 3 titles. In that era, there was only a single class in District 3 girls' volleyball.
By advancing to the finals, both Delone and Suburban earned berths in the upcoming state playoffs.
