The 2021 season will consist of two halves, with each half consisting of 24 scheduled games for each participating member team.
Winners of the first half in each division qualify for the playoffs, with winners determined by overall winning percentage in officially scheduled league games.
Every effort shall be made to play all games scheduled in the first half before the completion of the first half (the first half is considered complete for a team immediately prior to the date on which it’s originally scheduled to play its 25th official league game).
– In the event that a game scheduled in the first half cannot be completed until the second half, that game or games will count in the second-half standings.
– In the event of a first-half tie between two or more teams:
Tiebreaker #1: best head-to-head record (minimum of 3 games), determined by winning percentage, among all tied teams;
Tiebreaker #2: best head-to-head run differential;
Note: In the event of head-to-head records including first-half games for one team and second-half games for another, those games will count as first-half games for head-to-head tiebreaking purposes.
Note: In the event that more than two teams are tied, “head-to-head” records for each team will consist of that team’s record within the entire tied group of teams. This applies to all tiebreakers that involve head-to-head results. Example: If Teams A, B, and C are tied, consider Team A’s overall record vs. Teams B and C; Team B’s record vs. Teams A and C; and Team C’s record vs. Teams A and B. If two teams are tied for the best head-to-head record within the group, then the third team is eliminated, and two-team tiebreakers are implemented, beginning with Tiebreaker #1.
– In the event of further tie OR no head-to-head games,
Tiebreaker #3: best run differential against all WCL opponents through first half (according to schedule calendar);
Tiebreaker #4: best home win-loss record through first 24 games (according to schedule calendar);
Tiebreaker #5: coin flip.
The team with the best winning percentage in the second half of the season, as originally scheduled, wins the second half (which could include more than 24 games if rescheduled game(s) from first half is/are played during second half of season).
– If the team that won the first half also wins (outright) the second half, the remaining team with the best winning percentage over the full season qualifies for playoffs as wild card.
– If the team that won the first half finishes the second half tied for first place (by winning percentage), and that team is tied with only one team, the latter team qualifies for playoffs as second-half winner.
– If the immediately preceding paragraph does not apply and there is a tie for second playoff spot between two or more teams tied with best overall record OR tied for the second-half lead (as determined by winning percentage), the following tiebreakers apply:
Tiebreaker #1: best head-to-head record over the course of the entire season (not just the second half).
Note: In the event that more than two teams (not including the first-half winner) are tied, “head-to-head” records for each team will consist of that team’s record within the entire tied group of teams. This applies to all tiebreakers involving head-to-head results. Example: If Teams A, B, and C are tied, consider Team A’s overall record vs. Teams B and C; Team B’s record vs. Teams A and C; and Team C’s record vs. Teams A and B.
Note: If multiple teams are tied for the best head-to-head record within the group, remaining team or teams are eliminated before returning to Tiebreaker #1.
Note: If the team that won the first half is among the teams tied for the best second-half record, then that team is not considered for head-to-head tiebreaking purposes. In the first Note above, if Team C was the first-half winner, then head-to-head results are exclusively between Team A and B.
Tiebreaker #2: best full-season record against the team that won the first half;
Tiebreaker #3: best run differential against divisional opponents over entire season;
Tiebreaker #4: best home win-loss record for the entire season;
Tiebreaker #5: coin flip.
Note: Teams must play a minimum of 18 games in a half-season to qualify as winner of that half. To qualify as wild card with second-best full-season record, a team must finish the season having played at least 42 official league games.
WCL Divisional Series: Playoffs start the second full off-day following the last scheduled regular-season game of the WCL schedule.
Best of 3, with Game 1 hosted by second-half qualifier/lower seed, and Games 2 and (if necessary) 3 hosted by first-half qualifier. There are no off-days during the WCL Divisional Series.
WCL Championship Series: Championship Series starts the second full off-day following what would be a scheduled Game 3 of the Division Series.
Championship series is best of 3, with the lower-seeded team a) being the team with the lower winning percentage over the full season, and b) hosting Game 1 of the championship series.
In the event that both teams in the championship series finished with identical full-season records, the following tiebreakers shall be applied:
Tiebreaker #1 – full-season divisional record
Tiebreaker #2 – full-season run differential
Tiebreaker #3 – coin flip
Games 2 and (if necessary) 3 will be hosted by higher seed. Travel day will be scheduled between Games 1 and 2, but may be waived with assent of both teams.
