The second round of the CWAC’s battle of the unbeatens could be a doozy.

Fifth-ranked Prosser and No. 8 Selah own identical 7-0 records as they head into Friday night’s conference heavyweight bout at Art Fiker Stadium.

The Mustangs haven’t been this unbeaten this late in a season since a 2008 run to the Class 2A title game, while the Vikings are trying to match its historic 2017 season when they finished the regular season and advanced to the state quarterfinals.

It’s the second of three weeks that feature a monster conference matchup with CWAC and state implications. Last Friday, it was Prosser shaking off a sluggish start to beat East Valley 42-24 in a contest that both teams entered 6-0.

Mustangs coach Corey Ingvalson couldn’t pin down the reason for the slow start, something they also had to overcome in Week 2 against Othello.

“I don’t know if there’s anything to it,” Ingvalson said. “We by all means need to string together more quarters. Against Selah, we’re going to need to do that.”

While Prosser’s offense has taken a bit to get going in a couple games, the defense has been staunch from the start, holding all but the Red Devils to one score or less.

With Vikings standout running back Calen Wuitschick coming to town, the Mustangs again will need to be at its best.

Prosser knows it will see plenty of Wuitschick, who already has rushed for 22 touchdowns and nearly 1,300 yards a game. Against West Valley of Spokane, Wuitschick carried the ball 34 times, and also was called on more than 20 times against Othello and Toppenish.

“People know he’s getting the ball and he can still do it,” Ingvalson said. “We know we have a great challenge ahead of us.”

First-year starting quarterback Jerrid Scribner has offered balance to Selah’s offense. The junior has thrown for nearly 900 yards with 15 touchdowns against four interceptions.

Whether it was absences in the lineup or metered usage, Prosser might not have shown all of which it’s capable. Star junior receiver Brody Buxton was out the first two games of the season, and stout running back Korby Hopwood has carried the ball just 32 times this season, at nearly 9 yards a pop.

Ingvalson said getting his team to be patient will be key.

“Instead of taking singles, we want to hit a grand slam,” Ingvalson said of the first halves against the Huskies and the Red Devils that saw the Mustangs trailing at halftime. “It’s the understanding that it’s a four-quarter game. We need to take what they give, and even if you don’t score, you can flip the field.”

The matchup will be the second against a top-10 opponent for the Vikings. West Valley, the defending 2A champion of the Greater Spokane League, entered the Week 5 contest at Karl Graf Field ranked eighth.

A 29-24 victory against the Eagles gave Selah a boost.

“In hindsight, it was big for confidence,” third-year Vikings coach Greg Haste said of the game in which Wuitschick ran for nearly 300 yards. “Especially against bigger offensive linemen and bigger defensive linemen.”

Prosser will have a size advantage up front with 6-foot-3, 315-pounder Alex Barreras leading the way.

While Prosser will complete its round-robin against the conference’s other top teams and head to Ephrata next week, Selah will host East Valley (6-1).

It’s another step in the journey that the Vikings have embraced.

“Our whole team had bought into loving each other and playing good football," Haste said.  “We’re about the process and enjoying our time. All of the kids deserve this type of game.”
