Oregon’s season appeared to have turned the corner after it took two out of three against conference leader Cal and swept USC at home. Then the Ducks ran into UCLA.

The Bruins (19-18, 9-9 Pac-12) completed a three-game sweep of the Ducks (17-16, 7-8 Pac-12) in Los Angeles with a 13-1 victory Saturday that included 14 hits.

The Bruins got off to a hot start at the plate and the Ducks could do little to slow them down. Luke Perisco hit a two-run home run and UCLA sent 10 batters to the plate against starting pitcher David Peterson in the first inning. The Bruins’ 4-0 lead was extended to 10-0 in the fifth, when they batted around the order again and knocked Peterson out of the game after seven runs on nine hits in 4.2 innings. The Ducks’ bullpen surrendered three more runs in the sixth.

UCLA starting pitcher Kyle Molnar shut down the Ducks, allowing just two hits and no runs in 7.0 innings. Oregon scored its lone run in the ninth inning on a single from Steven Packard that scored Kyle Kasser.

The Ducks return home to face Oregon State on Wednesday and Washington in a three-game series starting Friday.
