DANVILLE -- The De La Salle High football team fought off a tough performance by San Ramon Valley's defense to earn a 34-9 nonleague win Friday night.
The Spartans (9-0) outscored the Wolves 21-6 in the second half to pull away. Tiapepe Vitale rushed for 131 yards, Das Tautalatasi ran for 114 yards, and quarterback Chris Williams scored three touchdowns.
"They came out and played us tough," De La Salle coach Bob Ladouceur said of the Wolves. "They're a very good football team. Their record's not indicative of how good they are."
The score also didn't reflect how well the Wolves (4-5) played. After starting the season 0-3, San Ramon Valley can earn a share of the East Bay Athletic League title with a win over Monte Vista next week.
California already clinched at least a share of the title with its win over Granada, and the Grizzlies own the head-to-head tiebreaker over the Wolves.
"You play like that against any other team in the North Coast Section, you've got a shot to win," San Ramon Valley coach Mark Kessler said.
The Wolves forced four De La Salle punts in the first half. But on the first of those punts, San Ramon Valley committed the type of the mistake that the Spartans often capitalize on when it was flagged for roughing the kicker.
On the next play, Williams hit Austin Lonestar for a 45-yard pass play. Four plays later, Williams scored on a 1-yard run for a 7-0 lead.
The Wolves got two more stops before De La Salle struck again. Vitale broke a 33-yard run to give the Spartans a 13-0 lead in the second quarter.
San Ramon Valley pulled to within 13-3 at halftime on a 42-yard field goal by Cal-bound kicker Matt Anderson, who earlier was just short on a 57-yard attempt.
De La Salle caught a break in the third quarter when Tautalatasi fumbled, but Williams recovered and ran it in for the touchdown.
Williams and John Velasco added rushing touchdowns for the Spartans before San Ramon Valley's Matt Winaker scored on a 2-yard run with 1 second to play.
