TEMPE, Ariz. -- Arizona State turned the Territorial Cup into a runaway.
Next up for the Sun Devils is the Pac-12 Championship game, back at home and with a spot in the Rose Bowl on the line.
No. 12 Arizona State dominated rival Arizona with a first-half onslaught and never let up, dismantling the Wildcats 58-21 Saturday night to earn home-field advantage in next week's Pac-12 title game.
"The advantage to play at home, you can't put a price tag on that -- it's huge," Arizona State coach Todd Graham said. "There's no question we play our best football here."
They sure did against Arizona.
Arizona State (10-2, 8-1 Pac-12) won last year's game by scoring 24 points in the fourth quarter and raced out to a 27-point lead by the midpoint of the second this time.
The Sun Devils had no trouble moving the ball without leading scorer and rusher Marion Grice, spreading it around to score the second-most points in Territorial Cup history win their seventh straight game overall.
D.J. Foster carried the load with Grice on crutches, rushing for 124 yards and two touchdowns after spending most of the season primarily as a receiver. De'Marieya Nelson did his part, too, pounding in a pair of scoring runs.
Taylor Kelly complimented the ground game, throwing for 274 yards and a pair of touchdowns.
Arizona State's defense was just as good, stuffing Arizona's run game early and forcing four turnovers, including a 64-yard interception return by Damarious Randall in the third quarter.
With another dominating performance at home, where they're 7-0 this season, the Sun Devils get one more game at Sun Devil Stadium, next Saturday against No. 8 Stanford with a chance for their first Rose Bowl since 1997.
"It means everything," said Nelson, who made the most of his 35 yards. "It's a great day for our seniors and this place is going to rock next week."
Arizona (7-5, 4-5) fell flat in trying to boost its bowl pedigree.
Ka'Deem Carey ran for 157 yards and a touchdown, but the Wildcats couldn't get out of their own way and had no chance of stopping Arizona State's offense.
B.J. Denker had three interceptions after throwing four the first 11 games of the season and Arizona failed on three fourth-down attempts to end the regular season with its most disappointing performance of the season.
"It's hard right now," Arizona coach Rich Rodriguez said. "We are all going to be ticked off for 24 hours or more and all that but this shouldn't define our senior class, it shouldn't define our team because we had some nice wins."
The Territorial Cup is the oldest rivalry trophy in college football -- dating to 1899 -- and the 87th version had an added dash of hype, fueled by momentum and raised stakes.
Both teams were coming off their biggest wins in years: Arizona over Oregon and Arizona State over UCLA.
With the Wildcats in town and so much on the line, Sun Devil Stadium was packed, a buzz in the air like few times over the past several years.
The Sun Devils put on quite a show, too, running over and through the jittery Wildcats in the first half.
On offense, Arizona State didn't seem to miss Grice (injured leg), using a mix of pass and run to score on its first four possessions.
Zane Gonzalez made a pair of field goals, Kelly used a fake to set up Darwin Rogers for a 38-yard touchdown and Foster ran for 50 of 53 yards on a scoring drive he capped with a 14-yard touchdown run.
Nelson added his first career touchdown, a 1-yard run to put Arizona State up 27-0 midway through the second quarter.
"I have a lot of confidence in the guys that they would step up and fill that role," Kelly said of replacing Grice.
The Wildcats didn't seem ready for the spotlight.
Arizona opened with a delay of game penalty before getting off its first snap, went backward on its opening drive and gave Arizona State the ball at the 24 when Drew Riggleman shanked a 12-yard punt over ASU's bench.
After holding Arizona State to a field goal, the defense had a breakdown, biting on what it thought was a run play to leave Rogers wide open for a TD.
Denker then threw a ball up for grabs into double coverage, leading to an interception by Alden Darby that set up Nelson's TD run.
Arizona also had trouble getting Carey going, too -- some of it apparently by design.
The nation's second-leading rusher didn't have a carry in the first nine minutes and was twice stopped on fourth down near midfield. On the first try, he lost seven yards, giving Arizona State a short field to set up Foster's touchdown run.
"It was them forcing B.J. to keep the ball," Carey said. "We corrected it later in the game, but it was too late."
Arizona did get a little momentum going in the second quarter, marching in for a 1-yard touchdown run by Denker.
After Arizona's Jake Smith hooked a 42-yard field goal wide left, Gonzalez made one from 23 yards in the half's closing seconds, putting the Sun Devils up 30-7 while breaking the school record with his 18th straight made field goal.
Carey finally started to find some room to open the second half and scored on an 8-yard run.
It didn't matter by then.
Denker followed with another mistake, missing an open receiver downfield and throwing an underneath pass that Randall intercepted and raced in for a touchdown.
Foster scored on a 7-yard run and Nelson went in from yard out, making it the most lopsided game in the series since Arizona State beat Arizona 56-14 in 1996.
"It's unbelievable to be here, but we still have a lot of work to do," Foster said. "We have to finish strong."
With their dominating performance, the Sun Devils have a chance -- at home, no less.
