TUCSON, Ariz. (AP) -- In what is already an odd Pac-10 season, Stanford, despite a 52-point loss to Texas, is looking like a contender, and Arizona (No. 17 ESPN/USA Today, No. 19 AP) looks nothing like the overwhelming favorite it was supposed to be.

Todd Husak threw for 364 yards, and freshman Kerry Carter rushed for three touchdowns in his first start Saturday night as Stanford routed the Wildcats 50-22.

	Arizona QB Ortege Jenkins, who was sacked five times, couldn't outrun the likes of Stanford's Andre Currie, left, and Matt Leonard on Saturday.

"I guess I'm surprised," Cardinal coach Tyrone Willingham said. "I don't think anybody envisioned us scoring 50 points. But I did feel if we executed, we could have a chance to win, even though this is one of the more difficult places to come and play."

Stanford (2-1 overall, 2-0 Pac-10) rolled for 578 yards.

"It is hard to say anything," Arizona coach Dick Tomey said. "This was an awful performance. It's a poorly coached football team. It's not a good football team. ... If anybody in this room can sleep tonight, they're not the men I thought they were."

Troy Walters, in a spectacular receiving duel with Arizona's Dennis Northcutt, caught eight passes for 168 yards.

"We have talent on this offense," Walters said, "and if we get things together and we execute, we're tough to stop."

Walters had seven catches for 164 yards in the first half. Northcutt caught eight for 139 yards and two touchdowns.

Stanford blew open a 30-7 halftime lead, fought off a rally by the Wildcats in the third quarter, then put the game away with three touchdowns in the first eight minutes of the fourth quarter.

"We've got the players," Husak said. "It's just a matter of me going out and getting them the ball and the running backs going out and doing what they do best."

The Cardinal, beaten 69-17 by Texas in its opener, has outscored Pac-10 opponents Washington State and Arizona by a combined 104-39 on consecutive Saturdays.

Carter, a 6-foot-2 and 225 pounds, adds a dimension that recent Stanford teams have lacked. He gained 79 yards in 20 carries.

"I just felt a lot better, a lot more confident, knowing that the coaches put their confidence in me enough to start me. I just wanted to go out there and prove that I deserved to be starting."

Arizona (2-2, 0-1), No. 4 in the preseason rankings coming off last season's 12-1 record, displayed weak defense in a season-opening 41-7 loss to Penn State, and it was even worse against Stanford.

Tomey had a blunt message for his players after the game.

"'See you here at 7 o'clock in the morning,'" he said he told them. "'Anybody not there is done. And I want your heads up.'"

Husak, who completed 21 of 35 passes on the night and ran 1 yard for a score, threw for 268 yards in the first half as Stanford amassed 347 yards. Stanford's Tim Smith intercepted three passes in the first half, and the Cardinal turned two of them into touchdowns.

Ortege Jenkins, who completed 15 of 23 passes for 200 yards and three touchdowns but was sacked five times, threw touchdown passes of seven and 15 yards to Northcutt in the third quarter.

On the second touchdown, Northcutt caught the ball in the backfield, then ran back to his left and raced into the end zone. Jenkins ran for the 2-point conversion to cut the lead to 30-22 with 1:01 left in the third quarter.

Husak drove the Cardinal 65 yards in five plays, capped by a 10-yard touchdown pass to Dave Davis. The kick failed and Stanford led 36-22 with 12:49 to play. The Cardinal put the game away with touchdown runs of 49 yards by Casey Moore and 44 yards by Cory Wire.

Arizona took a 7-0 lead in the game's first 1:44 on a 21-yard pass from Jenkins to Brad Brennan. Stanford scored the next 30 points, the first 24 in a span of 11 minutes, 14 seconds.

Carter had touchdown runs of 5, 8 and 3 yards.

Keith Smith replaced Jenkins briefly in the second quarter. Smith's first pass was intercepted by Tim Smith and returned 19 yards to the Arizona 20. Carter needed just two carries to score.

Trailing 24-7, Arizona drove from its 35 to the Stanford 1, but failed on two attempts to punch it in. Stanford went 99 yards in 11 plays for its final touchdown of the half, on Carter's 3-yard run with 2:12 to play.
