Norwin captured the first ever WPIAL Class 4A title and did it in style during a season to remember for the Knights. They won the Section 4 title with a 9-0-1 record to make it an outright title. Overall, Norwin was 21-1-1. The Knights defeated Canon-McMillan, 3-1, at Highmark Stadium to win the Class 4A title, the newest classification in the recently expanded WPIAL. Norwin coach Lauren Karcher also boasted Emily Harrigan, the Post-Gazette Player of the Year. The 5-foot-6 junior forward scored 32 goals and added 14 assists. She has started since her freshman year. The Rutgers recruit scored in a remarkable 18 of 23 games this season and her two goals in the WPIAL title game were the difference in the 3-1 result. As dominant as Harrigan was, there were times when she was not even the best player on her team. Senior forward Lexie Kolano scored 23 goals and had 18 assists for Norwin. Her 80 career goals are an all-time high at the program. Norwin's section rival Penn-Trafford won 15 games and reached the WPIAL quarterfinals. Another Section 4 team, Hempfield, won only four games all season but it made the playoffs and accounted for the only "blemish" on Norwin's regular-season with a 1-1 result at Hempfield.
In Class 1A, Greensburg Central Catholic was dominant once again. It featured a dominant goal scorer, but it ran into old nemesis Shady Side Academy once again and was denied a WPIAL or PIAA title. The Centurions won the Section 1 title outright by sweeping the Indians but they fell to them in the WPIAL final and PIAA semifinals in a pair of 1-0 results. Greensburg Central Catholic did finish with 21 wins and senior forward Bailey Cartwright finished her career with WPIAL records in goals (230) and assists (159). She scored 64 goals during her senior campaign and added 41 assists. The Notre Dame recruit ended her career with 14 hat tricks in a single season.
