The effort to bring a MLB team to Portland appears to be growing in seriousness, as Gordon Friedman of The Oregonian recently reported. Portland Diamond Project, the entity spearheading the effort, has submitted bids on two parcels that could potentially house 32,000-seat ballparks. Clearly, there’s still a long ways to go before anybody will be watching a major-league contest in Portland, but it’ll certainly be interesting to see whether that municipality (and a few others) end up as serious suitors for existing or expansion franchises.
