This season saw sixteen expansion teams, nearly tripling its size from 10 to 26 teams. It also marked the league's national expansion, with five of those teams coming from Visayas and Mindanao. This resulted in the league dividing into the North and South Divisions, although this only affected playoff seeding and not the overall format of the season, with the playoffs itself expanding to sixteen teams, eight per division.
Due to the much bigger size of the league, divisions were introduced to divide the teams into the North and South Divisions. Teams still play a single round-robin tournament as part of the regular season, but the playoff format was changed to accommodate the new divisions. The top eight teams from each division would advance to an expanded playoff tournament. Similar to the National Basketball Association (NBA), the champions from each division would face once another in what is dubbed the "national finals".
To ensure that the league remains balanced, a new rule was added so that teams were limited to only one Filipino-foreigner per roster, that player must also not be taller than 6'4" (193 cm). The player is classified as Filipino-foreigner if the player is a Filipino of foreign descent, regardless of being a Philippine passport holder. The new rule, however, caused some criticism from fans and players alike.[2][3]
Regular season
Format
The 26 teams played in a single round-robin format, playing one game against all other teams in the league for a total of 25 games. In each gameday, a series of games is played in a designated home arena, with the home team usually playing in the final game.
The playoffs were expanded from eight teams to sixteen teams in this season. The top eight teams in each division advanced to a four-round, single-elimination playoffs, playing in best-of-three series in the first three rounds, and a best-of-five series in the national finals, with homecourt advantage alternating between the higher seeds of each series in the first two rounds.

^Originally played on November 15, the game originally was an 82–81 Parañaque win. Due to a scoring error, the game would have been replayed at 81–81 in overtime, but Parañaque did not show up during the replay. Thus, the win was awarded to Bacoor City by forfeit.[4]
Not all games are in home–away format. Each team plays every team once. Number of asterisks after each score denotes number of overtimes played.
Teams in bold advanced to the next round. The numbers to the left of each team indicate the team's seeding in its division, and the numbers to the right indicate the number of games the team won in that round. Teams with home court advantage, the higher seeded team, are shown in italics.
In the first round, the first- and second-seeded teams host games 1 and 3 of its respective division, while the third- and fourth-seeded teams host game 2.
In the MPBL finals, the higher-seeded team hosts games 1, 2, and 5, while the lower-seeded team hosts games 3 and 4.
Both teams finished the season 20–5, but the Davao Occidental Tigers held the homecourt advantage for the finals, as they have defeated San Juan in their regular season matchup, but the San Juan Knights eventually won the championship in 5 games.
