The San Diego Surf Dawgs are an independent professional baseball team representing San Diego, California, that play in the short-season instructional Arizona Winter League and Arizona Summer League, based out of Yuma, Arizona. They played for two seasons in the now-defunct Golden Baseball League, which was not affiliated with either Major League Baseball or Minor League Baseball. They were the inaugural GBL Champions in 2005 managed by current Tucson Padres manager Terry Kennedy. Their now-former home stadium is named after former Padres great Tony Gwynn, and is located on the campus of San Diego State University. They have been owned by Diamond Sports & Entertainment, primary investors in the newly formed North American League, since 2005.
