The WPIAL softball playoff field is building with 51 teams having already punched their tickets for the upcoming district postseason.
The top four teams in each section qualify for the postseason from Class 5A down. In 6A, the top six teams clinch a WPIAL playoff berth.
If there is a tie for the final playoff spot in any section, all of the tied teams advance if they split their head-to-head meetings.
