Marlon Walker intended to take up space so a teammate could make a play, but instead it was the Berkeley High School linebacker's own hands that made the difference.

Walker slipped through the Castro Valley offensive line and blocked a 32-yard field goal attempt as time expired to help Berkeley secure a win over the visiting Trojans on Friday and the inaugural West Alameda County Conference-Foothill Division title.

"We are not out there playing for stats," said Walker. "We are out there to make plays and to play for each other."

Walker hoped to occupy two defenders so teammate Akil Bordelon could make the play. But when the Trojans focused on Bordelon, Walker slipped through.

Berkeley (5-4, 5-0 WACC-Foothill) trailed for all but 7 minutes and 12 seconds of the game, but took the lead with 1:22 left on Doug Stewart's 1-yard run that capped a 10-play, 60-yard drive and set the stage for Walker's heroics.

Castro Valley (5-5, 3-2) drove 65 yards on 10 plays, keyed by quarterback Luke Huerta's 19-yard pass to Robert Taylor and Patrick Cheek's 10-yard run to put the ball at Berkeley's 15-yard line with 4 seconds left.

"We had opportunities and did not take advantage," said Castro Valley head coach Nic McMasters, whose team was seeking its first league title in 15 seasons. "(Berkeley) did and they were the better team tonight."

The Trojans scored first on Demareyeh Lane's 5-yard run with 6:50 left in the first quarter to give Castro Valley a 6-0 lead.

Stewart responded for Berkeley with a 2-yard run midway through the second quarter to tie the game at 6-6.

Castro Valley's Huerta added a 16-yard touchdown run with 3:20 left in the first half to give the Trojans a 13-6 lead.

Berkeley capped the scoring with a 42-yard field goal by Samuel Boyden in the third quarter and then Stewart's touchdown run in the fourth.
