STANFORD, Calif. - Chris Lewis passed for one touchdown and ran for another and inexperienced Stanford stunned UCLA by sending the Bruins to their first conference loss, 21-14 Saturday.
The Cardinal, humiliated last week at Oregon 35-0, bounced back for the biggest victory in coach Buddy Teevens' two-year tenure.
Stanford did it by playing the complete game it had been looking for, with strong performances on offense, defense and special teams. Lewis, a fifth-year senior, played with poise as a fill-in for injured freshman quarterback Trent Edwards.
Lewis went 12-of-20 for 91 yards with an interception.
Luke Powell sparked the upset when he snapped a tie at 7 with a 90-yard punt return for a touchdown 2:28 before halftime.
Last week, Teevens predicted that a breakthrough win was coming soon for the Cardinal, saying his players have remained confident despite the frustrating results. But this didn't seem like the weekend Stanford would do it.
But the Bruins defense, which had been spectacular in recent weeks, was upstaged by Stanford's defense and several big plays by the Cardinal, which had its second-most points of the season and huddled at midfield after the win.
Stanford's effective blitzing scheme kept constant pressure on quarterback Matt Moore, who sat on the grass on both knees in frustration for several seconds after one long pass sailed well beyond his intended receiver. UCLA went to backup Drew Olson midway through the fourth quarter.
Olson led a scoring drive capped by Maurice Drew's second rushing TD of the game, a 2-yard run with 5:28 left, but the comeback effort fell short.
The Cardinal had eight sacks, three shy of its total for the season going in.
When Stanford punted late in the third, the ball hit off a UCLA player's leg and the Cardinal's Marcus McCutcheon, the son of former Rams running back Lawrence McCutcheon, recovered on the UCLA 8. That led to Lewis' 1-yard scoring run with one second left in the quarter.
That was one of several costly plays for UCLA, which would have maintained first place in the Pac-10 with a win and likely earned a Top 25 ranking.
