There's been a push to bring Major League Baseball (MLB) to Portland for almost 20 years. The effort was put back into the spotlight earlier this month when the Oakland Athletics announced they were exploring relocation options and Portland could be in the running. The Portland Diamond Project (PDP), which is the group dedicated to bringing MLB to the Rose City, confirmed the A's announcement in a statement to KGW. "PDP can confirm that we have engaged in talks with the Athletics, and plans for a visit by team officials are underway." So how did we get here? Here's a look back at the effort to bring MLB to Portland.
