The Ducks scored nine runs in the opening inning, the most since 1972, en route to the victory.
"After kind of a rough weekend, it was fun to play, and get some at-bats and have some success," second baseman Aaron Payne said, who was 2-for-2 with a run and an RBI.
Pilot starter Austin Kelly allowed eight runs before he could register a second out. The Ducks scored twice on Kelly wild pitches and reached base three times on softly hit balls to the infield. Oregon batted through the order once before the Pilots could get through the inning.
Mitchell Tolman had two hits in the inning and drove in two RBI (A.J. Balta both times).
Shaun Chase tagged a first pitch over the left field wall in the second inning to score two more runs and an 11-0 lead.
"Yeah I got a lot of it tonight. It was good after my first at-bat, because it was a pretty crappy at-bat," said Chase, who was the only Duck not to reach base the first time through. "I was trying to do too much and it showed."
Oregon starter Porter Clayton struck out the first four batters he saw, and made it through the first two innings unscathed, but ran into trouble in the third. Pilot second baseman Caleb Whalen connected on a three-run homer and Clayton loaded the bases before leaving after recording just five outs.
Oregon manager George Horton rode reliever Stephen Nogosek to three and a third innings without an earned run. The Ducks didn't allow another run until Derek Smith allowed four Pilots to score in the ninth. The rally was enough to get pitchers up in the bullpen.
"At least tonight when we weren't pitching extremely well, we hit the heck out of the ball," Horton said.
The first three Duck pitchers each hit the first batter they faced.
After the teams combined for 20 runs in the first four innings, they scored just five for the remainder of the game.
The game included 51 base runners, included 12 walks, seven hit by pitches and five wild pitches.
It was the the third time this season the Ducks have scored 14 runs or more.
