San Antonio
San Antonio is a huge city—in the top 10 in the US—with a climate more welcoming of baseball than other areas that need to think about, you know, snow and ice. The Spurs have done well there, and with more extensive cooperations such as USAA calling the Southern Texas city home, it wouldn’t be unthinkable for the MLB to put a franchise there.
Like Columbus—and actually even more eye-opening—San Antonio’s market reach isn’t overwhelmingly impressive. Tucked between Salt Lake City and Kansas City, sits San Antonio, at number 31, well below where you’d expect a city of that size to be. The Triple-A affiliate for the Brewers is currently there, but the stadium isn’t anything close to others when it comes to closing the doors.
The real question would be if Houston and Texas would be willing to open theirs.
