Manuta turned in a 41-yard touchdown run on Sierra’s first play from scrimmage and kept grinding his way to 107 yards on eight carries.
Manuta also turned in the play of the game when he dropped a Patterson defender with a stiff-arm and danced his way to a 50-yard touchdown in the third.
Devon Manaois collected a 13-yard pick-six, and Joey Cantu returned a fumble for an eight-yard score.
“Our defense played a great ball game,” Sierra head coach Walt Brookshire said. “Greyson Yarnell, Cantu and Kenneth Matela were big factors, and Matthew Elliott came off the bench and played some hard nosed football.”
Sierra held Patterson to just 91 yards of total offense.
Yarnell blocked a punt in the second, setting up a 35-yard Tyler-Ray Hewitt touchdown catch from quarterback Guillermo Nunez (8 of 15, 96 yards).
Manaois (four carries, 38 yards) made it 24-0 in the third with a five-yard run.
The Timberwolves (2-0) finished with 241 yards of offense.

Anthony Cota introduced Enochs to Guss Schmiedt Field with touchdown runs of four, 21, 22 and 64 as the Baby Buffs rumbled to their third straight win.
Cota finished with 154 yards on 17 carries, and Eddie Smith turned in 68 more on six carries, including a 19-yard touchdown run.
Ryan Fox (three carries, 66 yards) opened the scoring with a 30-yard scamper in the first, and Manteca took a 20-6 lead into the break.
Defensively, Matt Quiroga recovered a fumble, and Vince Carter sealed the win by stripping Enochs with 3:41 let.
Smith had a pair of sacks and Nick Burrows added one of his own.
“We dominated Enochs in all phases,” Manteca head coach Jon Shaefer said. “I was really impressed with the way we ran out two-minute offense heading into the half.”
Cota’s four-yard run came with 18 seconds left in the second capping a 65-yard drive that took just a minute and change off the clock.
“This is the third preseason game in a row where we have been pretty dominant,” Shaefer said. “We hope to continue this pace next week going into VOL play.”
