Whale Branch went on the road to St. John's on Friday night and pitched a shutout in the second half to win 28-14.
"We completely shut the water off," assistant coach and athletics director Carlos Cave said after the Warriors' third straight win.
On offense for the Warriors (4-5, 3-1), Amagee Stephens found Devonta Glover for two touchdowns through the air of 32 and 30 yards, while Stephon Eugene added a 2-yard scoring run.
Defensive lineman Nyles Pinckney returned an interception 47 yards for a touchdown.
And on special teams, Ben Wallace was 4 for 4 on PATs, with two touchbacks on kickoffs.
Now, Whale Branch travels to Allendale-Fairfax next Friday with a chance to be co-Region 5-A champions with a win.
"We've just got to feel good about how we're playing right now." Cave said.
St. John's fell to 5-4.
