Proposed MLB Franchises in Portland, Oregon

Portland, Oregon, remains one of the largest metropolitan areas in the United States without a Major League Baseball (MLB) franchise. Over the decades, several attempts have been made to bring a professional baseball team to the Pacific Northwest city, ranging from government-backed bids to private ownership groups.

Proposed Teams and Relocation Efforts

Montreal Expos Relocation (2002–2003)

When MLB announced the relocation of the Montreal Expos, Portland emerged as a candidate. Mayor Vera Katz and city officials presented a bid to the relocation committee. To support this, the Oregon State Legislature passed Senate Bill 5, securing $150 million for a new stadium. The plan involved using PGE Park as a temporary home. However, the Expos were eventually awarded to Washington, D.C., becoming the Washington Nationals.

Florida Marlins Possible Relocation (2006–2007)

Between 2006 and 2007, the Florida Marlins considered moving to Portland due to stadium funding issues in Miami. Local figures, including Portland native Johnny Pesky, advocated for the move. The proposed plan would have utilized the funds from Senate Bill 5 and expanded PGE Park to 25,000 seats as a temporary solution. Despite visits from Marlins officials, the team ultimately stayed in Miami and built LoanDepot Park.

Portland Diamond Ballpark Project (2017‘)

In 2017, MLB Commissioner Rob Manfred acknowledged an ownership group led by Craig Cheek and Mike Barrett, known as the Portland Diamond Project (PDP), working to bring a team to the city. The project has seen significant investment from high-profile figures, including NFL quarterback Russell Wilson and his wife Ciara, as well as former MLB player Darwin Barney.

The PDP has explored several sites for a potential stadium, including the Portland Public Schools headquarters and the Terminal 2 site at the Port of Portland. More recently, the project has shifted focus to the Lloyd Center shopping mall and the Redtail Golf Course in Beaverton. In September 2024, the PDP announced a letter of intent to purchase Zidell Yards in the South Waterfront neighborhood.

Recent Legislative Support

In June 2025, Oregon Governor Tina Kotek signed SB110, authorizing the state to set aside $800 million for stadium construction if Portland is awarded a franchise. This funding is designed to be repaid via income taxes from players and staff.

Market Potential

The Portland metropolitan area is a significant market, larger than those of the Cincinnati Reds, Kansas City Royals, and Milwaukee Brewers. With approximately 2.5 million residents as of 2022, it is the fifth largest metro area without an MLB team. Proponents argue that Portland's growth, livability, and strong television ratings make it an ideal location for a professional baseball franchise.
