The Redskins defense held Spring Valley to 231 total yards, including just 121 rushing yards on 44 carries.
Spring Valley was equally impressive defensively, allowing just 226 total yards, including 156 rushing yards on 37 carries.
"Situation-wise, our kids in the secondary have got to know the situation a little better there at the end of the game," Spring Valley coach Brad Dingess said. "But that touchdown pass was the only big play they had all night, so we held them pretty good.
"For as many points as they've been putting up, we did pretty good, we just made a mistake at the end. That one stung because it was the only one that mattered for them."
The Timberwolves opened the scoring in the first quarter when Jakob Frye plowed in from 5 yards out with 3:46 left. Kyle O'Neal's conversion made it 7-0. Frye led Spring Valley with 52 yards on 16 carries, while Colby Webb added 33 yards on 13 carries.
Hurricane answered when senior Zach Pate scored from the 4 midway through the second quarter. Brian Hughes converted the extra point to tie the score at 7.
Pate finished with a game-high 124 yards on 22 attempts.
O'Neal gave Spring Valley a 10-7 halftime lead with a 26-yard field goal as time expired in the second quarter, but as the dew fell and the temperature dropped, the field conditions deteriorated, and dictated a second-half defensive struggle.
"Now we start preparing for next week," Taylor said. "It doesn't really matter who we play or where we go because we're in and anything can happen in the playoffs, especially for a team like ours that's finally coming together.
"We're a good team and we have a heck of a senior class. I'm so proud of and happy for them. All that matters is we're practicing Monday."
