The Warriors had carried a 6-0 lead into halftime on the strength of a 2-yard plunge by Trevor Hamm with 29 seconds left before intermission.
The game got off to an inauspicious start when both teams moved backward on their opening drives, in each case as a result of a fumbled option pitch on third down.
After the third of six Chase County punts, PBHS took over with 5:21 left in the half, and 14 plays later, Hamm broke through with the initial score.
Thunderstorms moved into the area during halftime, delaying the start of the third quarter by more than an hour.
Late in the third frame, Chase County had its longest run negated a by a holding penalty deep in its own territory.
The flag made it first-and-20 at the Bulldog 7-yard line, and PBHS came within inches of dropping quarterback Shawn Talkington in the end zone for a safety on the next play.
One nearly-botched punt and three plays later, Ben Eldridge doubled the Warrior lead. Eldridge busted 35 yards up the middle for a clinching touchdown with 6:44 to go.
Chase County scored, but an interception by Elliott Spechtenhauser effectively ended the game with 34 seconds left.
Hamm totaled 116 yards on 33 carries and Eldridge added 71 on 14 attempts for the Warriors.
