Clovis High survived a scare to its No. 1 Central Section ranking Friday before putting away Atascadero 7-0 at Lamonica Stadium.
The Cougars overcame three turnovers to improve to 2-0.
Jaryd Weakley's 8-yard scoring pass to Garrett Olson with 37 seconds left in the first half was the difference.
Clovis limited Atascadero to 161 total yards.
Bobby Grijalva intercepted Atascadero's last-ditch pass in his own end zone and returned it to the 7 before falling to the ground as the clock ran out.
Ryan Davis also recovered a fumble to stop a Greyhounds drive at the Clovis 30 with 6 minutes, 10 seconds remaining.
