Affiliated Federations may enter their two best teams from their national championship played in the year before each MESC competition. The executive council of each Affiliated Federation must nominate and approve each team entering this competition. As a concession to the leading countries of men’s fastpitch in Europe, three teams may be entered by the countries which have finished in the first three places (medal winners) of the previous Men's European Championship.
The winners of the previous year SUPER CUP and CUP II automatically qualify to participate at the next event. The host country for each MESC may enter one extra team. The number one and two of the previous U-19 Men's European Championship are also qualified to participate. Up to two extra teams from outside Europe can be invited by EC ESF, who may also allow further participants in case of special circumstances. Other specific regulations available here.
