BSUK have a diagram of field dimensions available here.

BSB 6.8.3 No points will be awarded to either team in the case of a void fixture.

BSB 6.9 Calculating final league positions Final league positions will be primarily based on league points accumulated. However, should there be any ties on points within a league, they shall be split by the following sequential system:

BSB 6.9.1 A team tied on points who has conceded at least one voluntary walkover shall automatically be placed below any other tied teams who have conceded fewer voluntary walkovers. If a tie still exists, then BSB 6.9.2 or BSB 6.9.3 shall be followed as applicable.

BSB 6.9.2 Tie between two teams

BSB 6.9.2.1 Where two teams are tied on league points, the result between the teams will be the determining factor in placing one team above the other. Where fixtures are played on a ‘home’ and ‘away’ basis, the aggregate score of the two (or more) matches will determine the higher placed team. If this does not determine the higher placed team;

BSB 6.9.2.2 Runs data shall be used as per BSB 6.9.2.3 – BSB 6.9.2.4. If the tie on league points has been effected by any walkovers conceded to either of the teams or any void fixtures, all the relevant results against the team(s) which conceded the walkover(s) or the team(s) involved in the void fixtures (i.e. all the results between the teams tied on league points and the team(s) conceding the walkover(s)/void match(es)) will be removed from the results table and the recalculated runs data shall be used.

BSB 6.9.2.3 The team with the higher runs difference shall be deemed the higher placed team. If a tie still exists;

BSB 6.9.2.4 The team with the higher number of runs scored shall be deemed the higher placed team.

BSB 6.9.2.5 If the higher placed team cannot be determined from the system above, then this shall be determined by the toss of a coin by the BUCS Executive.

BSB 6.9.3 Tie between three or more teams

BSB 6.9.3.1 Where three or more teams are tied on league points, a 'mini league' table shall be formed to calculate the higher placed team from the results between the relevant teams using the following sequential system:

BSB 6.9.3.2 League points accumulated. If a tie still exists;

BSB 6.9.3.3 The team with the higher runs difference shall be deemed the higher placed team. If a tie still exists;

BSB 6.9.3.4 The team with the higher number of runs scored shall be deemed the higher placed team.

BSB 6.9.3.5 If the higher placed team cannot be determined from the system above, then this shall be determined by the toss of a coin by the BUCS Executive.

BSB 7 National Championship knockout competition specific regulations

BSB 7.1 BaseballSoftballUK (BSUK) shall organise the National Championship knockout competition on behalf of BUCS.
