The miracle upset is complete.

Thanks to an early surge on offense and a handful of Oregon miscues, Arizona shocked No. 5 Oregon 42-16 this afternoon at Arizona Stadium.

It was all Arizona from the beginning.

On Oregon’s first play from scrimmage, quarterback Marcus Mariota was intercepted by linebacker Scooby Wright. It was Mariota’s first pick of the season and ended a streak of 353 straight passes with no interceptions.

Cornerback Shaq Richardson got his hands on the ball first as he was falling out of bounds and tipped it to Wright, who returned it 13 yards to Oregon’s 45-yard line.

The Wildcats cashed in on the turnover when Ka’Deem Carey scored on a six-yard touchdown rush to cap off a nine-play drive and give Arizona an early 7-0 lead.

The Ducks went three-and-out on their next drive and the Wildcat offense went right back to work.

The UA put together a 10-play, 59-yard drive that resulted in a nine-yard touchdown pass from B.J. Denker to Nate Phillips to give Arizona a 14-0 lead midway through the first quarter.

Oregon finally got on the board when kicker Matt Wogan connected on a 33-yard field goal with 2:09 left in the opening quarter.

The Wildcats offense kept rolling in the second quarter.

On its first drive of the frame, Arizona marched 83 yards on 16 plays and finished it off with a five-yard touchdown pass from Denker to Terrence Miller to go up 21-3 early in the second.

Following the score by Miller, the Oregon offense finally reached the end zone. Mariota engineered an 11-play, 67-yard drive, which he capped off with a one-yard touchdown pass to tight end Pharaoh Brown. The Ducks ran a fake on the point-after attempt, but couldn’t convert to make it 21-9 in favor of the UA.

Arizona punted on its next two possessions and Oregon fumbled on its next two. When Mariota fumbled on fourth down near midfield, Arizona got the ball back and quickly went 59 yards in six plays to score again. This one ended in a one-yard touchdown run from Carey; his second of the game, to make it 28-9.

After the teams traded possessions to open the second half, the Arizona offense got hot again. Carey capped a nine-play, 70-yard drive with a nine-yard touchdown to put the Wildcats up 35-9.

The Ducks scored early in the fourth quarter to close it to 35-16.

Just when it looked like Oregon may start a comeback, Carey dashed those hopes.

Carey capped a 75-yard drive with a one-yard score to make it 42-16 and make the belief real.

Mariota was picked again later in the quarter by Richardson, trying to close the gap, and that iced the miracle win for the Wildcats.

Carey broke Trung Canidate’s school record for career rushing yards with a 20-yard gain on third-and-1 in the third quarter.

Carey came into the game needing 118 yards and finished with 206 yards on 48 carries.

The Canyon del Oro High School product was recognized on the Arizona Stadium videoboard at a timeout after the rush and received a standing ovation. Canidate is at the game and was also shown on the board.

Denker finished 19 for 22 for 178 yards, two touchdowns and no picks at the half. Miller had a team-high nine catches for 88 yards.
