EUGENE, Ore. – Oregon jumped on Oregon State early, and the 17th-ranked Ducks took round one of the 2010 Civil War series with a 9-4 victory at PK Park on Tuesday night.

In the third, Oregon’s two-out rally was initiated by Serna’s single up the middle, laced just over the head of Gorton. Piazzisi then belted a RBI triple to right center to plate Serna. Oregon State catcher Andrew Susac failed to call time and approached the mound with ball as an alert Piazzisi took off from third and scored to put the Ducks ahead 2-0.
The Ducks exploded for a five-run inning in the fourth, as Eddie Rodriguez doubled over the head of right fielder Dylan Jones. Steven Packard executed an exceptional bunt in front of home plate that moved Rodriguez to third and left Packard safe at first. Jack Marder then dropped a shallow RBI single into center that Aldaberto Santos dove for, but failed to hang on to the would-be highlight reel catch as Rodriguez scored to put the Ducks ahead 3-0.
With runners on first and second, Altobelli put down a sacrifice bunt in front of the plate that advanced Packard to third and Marder to second. Oregon State then relieved Gorton and brought Matt Boyd out off the bullpen. Curtis Raulinaitis put one into the infield that gave Stefen Romero trouble at third as OSU should have been out of the inning, but the error allowed Packard to score andMarder to move to third as Raulinaitis was safe at first and the Ducks went ahead 4-0.
With runners on the corners, the Ducks put the delayed double steal on and Raulinaitis took off for first. As the throw was made to second, Marder took off for home and scored to give the Ducks a 5-0 advantage as both were safe.
Boyd then walked KC Serna before Piazzisi ripped a bases-clearing, two-run triple to right center as Santos and Norris collided in the outfield and the Ducks took a 7-0 lead.
