Hernandez (elbow) walked two and struck out one over two-thirds of a scoreless inning for Triple-A Round Rock on Friday.
Hernandez kicked off a rehab assignment with the Express, his first game action since undergoing Tommy John surgery in April 2021. The right-hander had been a starter in the minors but served as high-leverage reliever for the Rangers prior to his injury. It's not yet clear now many rehab appearances he'll need before he's ready to be activated from the 60-day injured list.
