(Portland) -- After six years of trying, the Portland Diamond Project is a step closer to building a Major League Baseball stadium in the Rose City. Founder and president Craig Cheek says they have signed a letter of intent to buy the 33-acre former Zidell Shipyard along the South Waterfront. The group has three-and-a-half years to complete the purchase. The group has been working on bringing Major League Baseball to Portland since 2018.
