, an 8-team circuit divided into two divisions. Prior to the 2022 season, MLB renamed the Low-A West as the California League, and it carried on the history of the league prior to reorganization. In 2021, the Low-A West held a best-of-five series between the top two teams in the league, regardless of division standings, to determine a league champion. A league champion has been determined at the end of each season by either postseason playoffs or being declared champion by the league office. In 2019, the first-half winner in each division (North and South) received a bye into the second round, or division series. Each division's second-half winner and wild card team, the team with the best winning percentage over the entire season to have not won either half of the season, faced each other in a best-of-three series. The winner of this mini-series met the division's first-half winner in a best-of-five series to determine division champions. Then, the North and South division winners played a best-of-five series to determine a league champion. As of 2022, the winners of each division from both the first and second halves of the season meet in a best-of-three division series, with the winners of the two division series meeting in a best-of-three championship series.
