Senior Cristian Negrete kicked three field goals, senior tight end Speiser Alani scored on a six-yard pass from senior quarterback Dallas Broge, junior defensive back Tristan Wenschlag returned a fumble 75 yards for a TD, and junior running back Daniel Valencia scored on a school-record 99-yard run.

Seahawks Coach Luis Nunez said Valencia's 99-yard run was, "as 99 (yards), as it gets. The tip of ball was on the goal line."

Loara last week was defeated, 42-20, by league leader Westminster. Running back Connor O'Shea accounted for 125 yards of offense and rushed for two touchdowns, and quarterback David Gistlinck threw for 170 yards a score.

"It's going to be battle as it will take another great effort from our team to win," Nunez said. "We just need to win and worry how it plays out later."

The "later" Nunez is referring to, is the playoff scenario for the league. In two instances, if Ocean View defeats Loara, the Seahawks earn the No. 3 league seeding. The Seahawks would either have to take part in a coin flip, or be eliminated from playoff contention, in the other scenarios.

Westminster (4-0) travels to second-place Segerstrom (3-1) in a game that will determine the Golden West League champion. A Segerstrom win gives the Jaguars a share of the title with the Lions.

Brethren Christian (5-4, 1-1) vs. Crean Lutheran (5-4, 1-1)

(7 p.m., Crean Lutheran High)

Second-place and an automatic playoff berth hang in the balance when Brethren Christian goes to Irvine for a battle with Crean Lutheran.

Both teams have lost in league play to first-place St. Margaret's. BC lost, 51-14, last week to the Tartans (No. 2, East Valley Division) who broke open the game by scoring the final 20 points. Junior quarterback Jack McInally threw for 216 yards with two touchdown passes, both to sophomore receiver Guy Demazeliere, for the Warriors.

Crean Lutheran squared its league record last week by defeating winless Sage Hill, 28-7. The Saints rushed for more than 400 yards led by Blake Cox who ran for 252 and Adam Barrett who gained 123 and scored twice.

"This is so great. The winner goes to the playoffs," BC Coach Pat McInally said. "Crean continues to build its program and has a strong running game, which we will need to stop. Offensively, we need balance, a timely, effective mix of runs and passes."
