There's a minor league team in Utica, NY. And various amateur clubs across the country like in Lexington, MA. They use the name Blue Sox.
And there is a historical connection in name to my beloved Cincinnati area: wikipedia.org/wiki/Covington_Blue_Sox
|Across the river from Cincinnati|
Since I'm not of Portland, the decision is easy for me: the Portland Blue Sox.
|170 miles from Seattle and 600 from San Fran.|
An added reason that expansion is tough these days is revenue sharing between owners. You're asking them to get what might amount to a smaller slice of the pie. And you're asking them to relinquish television territory. So there is resistance to expansion. I think that the Giants would be much cooler with the Athletics relocating to Portland. And of course the Mariners want Portland to still root for them. It's a fight!
