Being an O's and baseball fan that has lived in Nashville for 17 years, I believe Nashville is primed to get a team either by relocation (Tampa, Oakland) or expansion, which is expected once the issues with the two teams I mentioned are resolved. Las Vegas is obviously a possibility, but from the extensive reading I've done on the subject, Portland seems to be the overwhelming favorite, followed by Vegas, Nashville, and San Antonio. I think a 3rd team in Texas is unlikely. Nashville opened a new AAA stadium downtown a few years back, and I believe they built it with the ability to expand down the road. The only issue is it would be only 3 hours from Suntrust in Atlanta.
