Rangers selected the contract of C Austin Wynns from Triple-A Round Rock.
Wynns fortifies the Rangers’ catching depth behind starter Elias Díaz while Kyle Higashioka is on the injured list with a flexor strain. The 35-year-old journeyman signed a minor league pact last month. He went 4-for-53 at the dish during a 20-game run with the Braves earlier this season.
