Small has forged a 100-33-27 career record over nine seasons - all at Gloucester.

"Emily Bucher, our center-mid, really stepped up today," Small said. "And the rest of the girls were really hungry and wanted this one. I was proud of them."
Angela Harris had the Lions other goal, off an assist by Johanna James. Joyce Perry scored for Schalick.
Gloucester improved to 3-0, while Schalick slipped to 2-1.
