# 1998 PBA All-Filipino Cup

The 1998 Philippine Basketball Association (PBA) Centennial All-Filipino Cup, also known as the 1998 McDonald's-PBA All-Filipino Cup for sponsorship reasons, was the first conference of the 1998 PBA season. It started on February 1 and ended on May 8, 1998. The tournament is an All-Filipino format, which doesn't require an import or a pure-foreign player for each team.

## Format

The following format will be observed for the duration of the conference:
* The teams were divided into 2 groups.
* Teams in a group will play against each other once and against teams in the other group twice; 11 games per team; Teams are then seeded by basis on win–loss records. Ties are broken among point differentials of the tied teams. Standings will be determined in one league table; teams do not qualify by basis of groupings.
* The top six teams after the eliminations will advance to the semifinals.
* Semifinals will be two round robin affairs with the remaining teams. Results from the elimination round will be carried over. A playoff incentive for a finals berth will be given to the team that will win at least seven of their ten semifinal games.
* The top two teams (or the top team and the winner of the playoff incentive) will face each other in a best-of-seven championship series. The next two teams will qualify for a one-game playoff for third place.
