HONOLULU — The stage is set for all three tiers of Oahu Interscholastic Association playoff football.

Saturday night’s action across the island – highlighted by a late surge by defending state champion Kahuku to defeat fellow contender Mililani 29-17 – concluded the OIA regular season and finalized seedings in the Open Division, Division I and Division II.

The top four teams qualified in each tier. Interestingly, there was no need for a head-to-head tiebreaker in any division, as records sorted out into a natural hierarchy over the course of the season, with one unbeaten team, one one-loss team, one two-loss team, and so forth.

The other final-weekend game to determine seeding was Aiea’s 31-10 win over Farrington on Friday. Na Alii locked up the No. 2 seed in Division I.

Here’s how it broke down with league records in parentheses, followed by the number of all-time OIA titles won by each school.

OPEN DIVISION

1.     Kahuku (6-0), 28 OIA titles (2 in Open era)

2.     Mililani (5-1), 4 OIA titles (1 in Open era)

3.     Campbell (4-2), 2 OIA titles (0 in Open era)

4.     Kapolei (3-3), 0 OIA titles (0 in Open era)

DIVISION I

1.     Waipahu (6-0), 12 OIA titles (1 in D-I era)

2.     Aiea (5-1), 2 OIA titles (1 in D-I era)

3.     Kailua (4-2), 4 OIA titles (0 in D-I era)

4.     Farrington (3-3), 1 OIA title (0 in D-I era)

DIVISION II

1.     Nanakuli (7-0), 2 OIA titles (1 in D-II era)

2.     Pearl City (6-1), 0 OIA titles (0 in D-II era)

3.     Kaiser (5-2), 3 OIA titles (2 in D-II era)

4.     Kaimuki (4-3), 3 OIA titles (3 in D-II era)

In each division, the No. 1 team will face No. 4 and No. 2 will host No. 3. The winners of the semifinal games will automatically qualify for their respective state tournament field.

In the Open Division, there will be a third-place game to determine the league’s final representative to states, as the OIA places three teams there.

Semifinal games will be played on Friday and Saturday.
