It's been a question ever since Nolan Ryan jumped ship and joined his son, Reid, in the front office for the Houston Astros after the 2013 season: When would the Rangers move their Triple-A affiliate away from Round Rock — an organization owned by the Ryans?
That time could be coming sooner rather than later.
Following the 2018 season, the agreement between the Rangers and the Express will lapse, and it's hard to imagine the sides re-upping. There lies the problem, because the Rangers love the easy access to both their Double-A and Triple-A affiliates — making for easy rehab assignments and easy player call-ups — but there might be a solution that is almost as good about two hours further down the road (80-90 minutes thanks to the awesome toll road around Austin).
According to The Dallas Morning News, the Rangers might be looking to sign on with the San Antonio Missions, which are currently the Double-A team for the San Diego Padres in the Texas League with the Frisco RoughRiders. That, of course, would mean the Padres would have to move, but that's not of the Rangers' concern.
It seems too logical not to happen, so you might as well just go ahead and count on it, even if it's still a couple of years down the road.
