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.
This was a monumental win for the Cardinal, who were humiliated last week at Oregon 35-0, and the biggest victory yet in coach Buddy Teevens' two-year tenure.
Stanford (3-4, 1-4 Pac-10) did it by playing the complete game it had been desperately 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 7-all tie with a 90-yard punt return for a touchdown 2:28 before halftime.
This 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 week Stanford would do it, considering UCLA's latest defensive success.
But the Bruins defense that has been spectacular in recent weeks was upstaged by Stanford's defense and several big plays by the Cardinal, who had their second-best scoring output 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 (6-3, 4-1) 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 the 11 they had all season coming into the game.
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 Los Angeles Rams running back Lawrence McCutcheon - recovered on the UCLA 8, giving Stanford great field position that led to Lewis' 1-yard scoring run with 1 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 also likely earned a top-25 ranking.
Stanford had allowed 51 points in the first quarter in its previous six games, but the Bruins didn't score until Drew's 9-yard TD run 57 seconds into the second quarter for a 7-0 lead.
That's when Stanford's vapid offense began to show signs of life for the first time in two games. Stanford had only 206 yard of offense but held UCLA to 287.
After failing on seven plays from the 2-yard line last week, Teevens got creative and went away from his conservative play calling in the red zone to give his team a better chance.
On third down, Lewis had three players lined up behind him to form an "I" - a tight end and two running backs. Lewis then found Matt Traverso wide open in the end zone for a 2-yard TD reception that tied the game at 7 with 9:06 left in the second quarter.
Powell's big run was the second-longest punt return for a touchdown in school history. Thomas Henley returned one 92 yards against Oregon in 1986.
