The Ducks (42-18, 18-12 Pac-12) got three runs back in the bottom of the fifth to get within two runs. Nick Catalano doubled to left field to score Steven Packard with the first run. Mark Karaviotis drove in Catalano with a RBI single to right and then scored on an Aaron Payne single.
Cal closer Trevor Hildenberger shut down Oregon's hopes of a rally for a win allowing just one hit in the final three innings while fanning three for his 10th save. Ryan Mason (7-1) picked up the win for the Bears allowing three runs (two earned) on five hits in six innings.
