Montgomery (elbow) will begin a rehab assignment Sunday with Double-A Frisco.
The left-hander has been working his way back from the hybrid UCL reconstruction surgery he underwent on his elbow in March 2025, and he's now entering the final stage of his rehab program. Montgomery will require a handful of rehab starts in the minor leagues before gaining full clearance, lining him up to potentially join the Rangers in late July or early August.
