EUGENE, Ore. - Arizona is turning out to be the master of upsets in the Pac-10. First Washington State, then mighty Cal, and finally Oregon — and at Autzen Stadium, no less.
Arizona (6-5, 4-4 Pac-10) has a modest three-game winning streak and is bowl eligible after a 37-10 victory over the Ducks on Saturday. The Wildcats will likely need to win Saturday against Arizona State to receive a bowl bid.
‘‘Sometimes it’s just your time, and we feel that it is ours. We feel good about the way we are playing now,’’ coach Mike Stoops said. ‘‘We have a big game next week against Arizona State, and hopefully we’ll have a lot of options in December.’’
Arizona, which has won three straight, is above .500 for the first time since Nov. 10, 2000. The Wildcats have not had a winning season since 1998.
Arizona was coming off a surprising 24-20 victory over then-No. 8 California last weekend, and a 27-17 upset of then-No. 25 Washington State in Pullman a week before.
Against Oregon, running back Chris Henry took over, running for 191 yards and two touchdowns and also pulling down a scoring pass.
Quarterback Willie Tuitama started for Arizona but left before halftime after the team said he had a concussion. He completed eight of nine passes for 120 yards and two scores. He watched from the sideline after he was replaced by Adam Austin.
‘‘It’s worn off, I can tell. I spent some time talking to him and he’s a lot more alert. He just took a pretty good shot helmet-to-helmet,’’ Austin said.
Tuitama had missed two games earlier this season because of a concussion and had been fitted with a special helmet.
It was the first loss of the season at Autzen Stadium for Oregon (7-4, 4-4).
Dennis Dixon went 14-of-22 for 88 yards and threw three interceptions for Oregon. He was replaced by Brady Leaf, who was intercepted on his first series.
The Ducks also lost a pair of fumbles.
‘‘We need to get better in a hurry,’’ Oregon coach Mike Bellotti said. ‘‘Right now, we have certainly hit a plateau, or gone backward, and that’s frustrating. I think it’s tied to turnovers, and the play at quarterback. We have to evaluate that and make sure that it improves in a hurry.’’
Oregon took an early 3-0 lead on Paul Martinez’s 27-yard field goal, but Patrick Chung fumbled a punt return that was recovered by Spencer Larsen on the Oregon 15. Henry ran it in on the next play to put the Wildcats in front 7-3.
Tuitama hit Earl Mitchell for a 37-yard scoring pass that made it 14-3.
The Ducks answered with Jeremiah Johnson’s 8-yard scoring run early in the second quarter, but Arizona extended its lead on the next series when Henry scored on a 21-yard pass from Tuitama.
Dixon was intercepted for a second time before halftime, when the ball was tipped at the line of scrimmage and caught by Ronnie Parker. The Wildcats went on to score on Nick Folk’s 29-yard field goal.
Folk added a 28-yard field goal in the third quarter before Henry scored on a career-long 61-yard TD run. Folk kicked a 45-yard field goal early in the fourth.
‘‘It feels really good, but it feels even better just to win,’’ Henry said of his career day.
Oregon plays the season-ending Civil War game on Friday at Oregon State.
