Oswego Co-op senior Ava Sullivan wrapped up the most successful state performance by an individual Oswego co-op gymnast on Saturday at Palatine, winning the vault to become the school’s first state champion. She also took second on floor and third on beam.

Downers Grove co-op's Genevieve Herion added to her long list of accomplishments while putting the Trostangs in wonderful position to win a state championship. The senior won the all-around Friday, and her team scored a school-record 148.45 points at the state meet.

Genevieve Herion won the all-around, vault and beam, tied for first on floor and took second in bars to lead Downers Grove co-op to the Hinsdale Central Sectional title Monday and advance to state for the fifth straight season. Lincoln-Way co-op was second and Oswego co-op third.
