Perez (ankle) was reinstated from the 10-day disabled list and assigned outright to Triple-A Round Rock on Monday.
Perez had already been with Round Rock on a rehab assignment but will now be there as a full-time member of the team. He's also been removed from the 40-man roster, which hurts his chances of returning to the big-leagues any time soon and leaves Isiah Kiner-Falefa as the Rangers' backup catcher.
