The Blue Devils scratched out nine runs despite just one extra-base hit against Sidney.
Taia Tully's double broke up Corvallis' station-to-station hitting. She hit a double in the bottom of the second and later scored the inning's only run on a Hannah Capko sacrifice fly, putting the Devils ahead 4-0.
Corvallis added two more in the third inning on an error and a Bobbie Stephen RBI base hit. That put the Blue Devils ahead 6-0, enough to weather Sidney's five-run rally between the fourth and fifth innings.
