It seems that it was just yesterday that the 2025 OSSAA baseball season started. But this week the 2025 postseason gets started with Districts in classes A-1, A-2, and B.

With the addition of another classification in Class A this year, the playoff structure has changed a little. Per the OSSAA website:

For Class A-I & Class A-II, the teams will utilize the following structure:

Class A-I & A-II teams will rank all season through ossaarankings.com. The 16 top ranked teams in each Division will receive District byes. The #17-48 teams will be paired in a two team best of three series, with those 16 winners advancing to the Regional Tournament.

The remaining 32 teams will be placed in 8 Regionals of 4 teams each, with the Top 8 Ranked teams serving as Host Sites during Week 43 of the OSSAA Calendar, utilizing the Bracket structure from Page 16 of the Baseball Manual.

The 8 Regional Winners will advance to the State Tournament during Week 44 of the OSSAA Calendar.

For Class B, the teams will utilize the following structure:

Class B teams will rank all season through ossaarankings.com.

There will be 32 District Tournaments comprising either 2, 3, or 4 teams depending on the number of teams participating in Class B. The District Tournament will be double elimination, with the higher ranked team hosting during Week 42 of the OSSAA Calendar.

The remaining 32 teams will be placed in 8 Regionals of 4 teams each, with the Top 8 Ranked teams serving as Host Sites during Week 43 of the OSSAA Calendar, utilizing the Bracket structure from Page 16 of the Baseball Manual.

The 8 Regional Winners will advance to the State Tournament during Week 44 of the OSSAA Calendar.
