The Salem-Keizer Volcanoes began play in the Northwest League in 1997 when the Bellingham Giants relocated to Keizer, Oregon. The Volcanoes captured league titles in 1998, 2001, 2006, 2007 and 2009.
On August 21, 2017, the Volcanoes scheduled a home game against the Hillsboro Hops for 9:35 a.m. that Monday morning. This was no mistake, as the game was scheduled to fall directly during the total solar eclipse passing over the Willamette Valley as part of its path over much of the United States that day. The ballpark was in the narrow band that would experience a couple of minutes of total darkness that day, and the game, dubbed the "Eclipse Game", was scheduled to take full advantage of this, with a built-in "eclipse delay" at approximately 10:17 am. The game was to be preceded with breakfast served to fans from 6 to 9 a.m. With all the associated merchandise linked to the game, it turned out to be the biggest promotion in team history.
