在美國大學跟高中的比賽都沒有固定的場數大學的話從 50 場打到 70 幾場的都有大學分的更多大學有分 Division I

Divison II

和 Division III當然Division I 是最強的每個Division 中又有分很多個 Conferences公認競爭最激烈的是 Big West Conference (你可以注意到全都是加州的球隊)以下是所有Division I 的球隊America East ConferenceSchool Name City ST Zipcode Region University at Albany Albany NY 12222 Northeast State University of New York at Binghamton Binghamton NY 13902-6000 Northeast University of Hartford West Hartford CT 06117-1599 Northeast University of Maine
