Heading into halftime locked at 14-all with UCLA, No. 2 Oregon didn't panic. The Ducks knew they'd eventually wear down the No. 14 Bruins. Because that's what they do. "We understand that our tempo is one of our greatest allies," sophomore quarterback Marcus Mariota said. Oregon went on to score 28 unanswered points in the second half and beat UCLA 42-14 on Saturday night. Byron Marshall ran for 133 yards and three touchdowns, Mariota threw for 230 yards and another score, and the Ducks (8-0, 5-0 Pac-12) racked up 555 yards in total offense compared to 283 for UCLA (5-2, 2-2). "We just had to keep chipping away," Mariota said. We knew that if we kept getting 5- or 6-yard chunks, we were going to get into a rhythm. "That was a very disappointing loss," Bruins coach Jim Mora said. We didn't come up here to play them close, we didn't come up here to give it the old college try. We came up here to win the game and we didn't get it done and it's very disappointing. UCLA, which has now lost two straight after falling to Stanford last week, has not won at Autzen Stadium since 2004, and hasn't defeated the Ducks since a 16-0 blanking in 2007. 16 Washington at Husky Stadium. "In the first half we had a couple of runs we'd like to have back, and a we had a couple of throws we'd like to have back," Ducks coach Mark Helfrich said. But we finished right where we wanted to finish. Oregon got off to a poor start, stymied by its own mistakes and UCLA's stout defense. But Rodney Hardrick ran 66 yards on a fake punt and De'Anthony Thomas finished it off with a 1-yard dive for an Oregon touchdown to even the score. He finished with 31 yards rushing against the Bruins. Alejandro Maldonado's punt for the Ducks was blocked late in the half, putting UCLA in Oregon territory.
