CONCORD -- The Livermore High football team has experienced minimal success against De La Salle's defense these past few years, and the Spartans proved to be just as frustrating Friday night.
De La Salle won 57-0, earning its first shutout of the season. It also marked the fifth consecutive time that the Spartans haven't allowed a single point to the Cowboys (2-3).
Livermore came into the game averaging 313 rushing yards, but the Spartans allowed just 53 yards on the ground at Owen Owens Field on Friday.
The stifling defense let the offense work with short fields all night, and it took advantage. The Spartans (5-0) put points on the board on six of their seven first-half drives, failing only because of a bad snap on a field-goal attempt.
Allan Marion put De La Salle up 7-0 before the offense even stepped on the field, returning a punt 61 yards for a score. The Spartans continued to score quickly and often.
Tiapepe Vitale rushed for four first-half touchdowns, and Kyle Mouton had a team-high 130 yards on nine carries, including a 43-yard TD run.
The Spartans led 43-0 at halftime.
Running back David Riopelle, now recovered from an anterior cruciate ligament injury in his knee, made his season debut in the second half, rushing for 69 yards and a touchdown.
On the other side of the ball, Michael Hutchings and D.J. Moffitt led a Spartans defense that didn't allow Livermore past midfield all night.
De La Salle relied on its backups for the entire second half when a running clock was used.
