NEW HAVEN, Conn. – There will be two very special additions to the Yale softball roster this season. Six-year-old Hailey Greist and her seven-year-old brother Edwards Greist have joined the Bulldogs through Team Impact, whose mission is to improve the quality of life for children facing life-threatening and chronic illnesses through the power of team.

Hailey and Edwards are both from Stratford, Connecticut, and have been diagnosed with common variable immunodeficiency, an immune disorder where children have very low antibody levels and are very susceptible to infections.
