Ocean View missed a chance to move into a share of the league lead with Segerstrom which now has a two-game lead on the Seahawks with one game left in the regular season.
Segerstrom's win earned the Jaguars (8-1 overall, 4-0 in league) no worse than a share of the Golden West championship.
The loss dropped Ocean View to 2-2 in league and 6-3 overall.
"Our kids have a habit of hanging in there and fighting back when we've been down," Ocean View Coach Harold Eggers said. "We've done that several times this year. The kids fought to the very end and you can't ask for more than that. It was turnovers, though, that really hurt us tonight."
The teams traded punches in the first half although Segerstrom had the upper hand at halftime with a 15-8 lead. The Jaguars went deep into Ocean View territory on their first two possessions of the second half only to see the Seahawks rise to the occasion and come up with two huge defensive stops. The first came on a goal-line stand when a host of Seahawks stuffed Segerstrom quarterback Max Padilla for no gain on a fourth-and-goal run from the one. The second came two minutes later when junior lineman Tyren Hudson intercepted a second-down pass by Padilla after the Jaguars had started their next drive at the Ocean View 22-yard line midway through the third quarter.
The Seahawks then mounted an 11-play drive that took them from their 22 down to the Segerstrom 11. But on second down from the seven, quarterback Nolan Tippy, who appeared to keep the ball after faking an inside hand off to junior running back Timmy Robinson, fumbled. Segerstrom's Ruben Martinez pounced on the loose ball at the nine to end the scoring threat.
