The Rangers aren't willing to part with one of their young shortstops, which could keep them from landing Justin Upton in a trade with the Diamondbacks.
According to rival executives, if Texas loses ground Tampa Bay could emerge as the most likely destination for Upton.
The Rays could offer a top-of-the-rotation starter, which Diamondbacks covet.
They could not have afforded both Justin and his older brother, B.J., but B.J. rejected the team's qualifying offer on Friday.
