The Golden Baseball League was an independent minor league in California, Arizona, Utah, and Canada whose member teams were not associated with any Major League Baseball teams. It operated from 2004 to 2010.
The GBL did not use the designated hitter rule; rather, pitchers batted for themselves. Player salaries ranged from $750 to $3,000 per month. Each team's entire payroll was less than a third of what the major league mininum is for one player ($316,000).
The GBL's presenting partner was Safeway Inc. Other investors in the GBL included Wheel of Fortune host Pat Sajak, former National Football League players Mike Sherrard and Christian Okoye, and executives from Cisco Systems, Taleo, and Draper Fisher Jurvetson, among others. David Kaval was the league's co-founder, chief executive officer and interim president.
In its final years the league operated as a ten-team circuit composed of two divisions. The GBL had planned to add additional teams in California and Arizona, plus teams in Oregon within five to seven years. Following the 2010 season the league merged with the United Baseball League and Northern League to create the North American League. The franchises in Calgary, Chico, Edmonton, Maui and Yuma all survived the move and became the members of the North American League.
