LITHIA — Clint Carnell rushed for two touchdowns to help lead the Wolves.
Keller Powers got Newsome on the board first, his 2-yard run capping an eight-play, 80-yard opening drive. Chamberlain responded on its first play, Xavier Johnson going 64 yards untouched.
The Wolves and Chiefs nearly matched each other score for score in the first half. Carnell notched his first touchdown with 5:40 left in the first quarter to give Newsome a 14-7 lead. But Chamberlain responded with a 4-yard run by Neil MacInnes to tie it.
Newsome's Jorge Thompson broke numerous tackles on his 12-yard run with 3:28 left in the half. But MacInnes' 45-yard field goal with 14 seconds left made it 21-17.
Carnell iced the contest with a 4-yard touchdown run in the fourth.
"The best defense is a good offense," Newsome coach Ken Hiscock said. "We take pride in that and got it done."
