SEATTLE >> For all the attention quarterback Michael Penix Jr. has deservedly received this season, it was the oft-maligned defense for No. 5 Washington that showed up for the final 30 minutes on Saturday and left the Huskies sitting at 10-0 for only the second time in school history.

Penix threw for two touchdowns and ran for another, and Washington pitched a shut out in the second half to rally for a 35-28 win over No. 13 Utah.

The Huskies (10-0, 7-0 Pac-12, No. 5 CFP) extended the second-longest active win streak in the nation to 17 games and stayed in the middle of the College Football Playoff conversation. The only other time Washington reached the 10-0 mark came in 1991, when the Huskies claimed a share of the national title with Miami.

“It’s all the work we’ve put in. We’re right where we saw ourselves at. We just have to continue to keep working,” Penix said. “We’ve got two more in the regular season to try and finish off with two more wins, go 12-0, and it’s right there in front of us.”

Penix wasn’t at his best on a blustery day on the shore of Lake Washington. But he made enough big plays in the pass game and allowed Washington’s defense to make key adjustments at halftime after being unable to slow down the Utes in the first half.

Washington watched Utah score touchdowns on four straight possessions at one point of the first half. In the second half, Utah had six possessions and crossed midfield only once.

“We know we we didn’t come out and play our best brand of football in the first half. But that’s how it should be every game. We should come out and play like we did in the second half every game,” Washington cornerback Jabbar Muhammad said.

Penix hit Rome Odunze on both of his touchdown throws, and ran for a 2-yard TD in the first quarter. Penix was 24 of 42 passing for 332 yards. Odunze had three catches for 111 yards and Dillon Johnson rushed for 104 yards.
