EDGE Analysis

Instead, Darvish will face live hitters in a controlled environment once more, but there has been nothing to suggest he suffered a setback of any kind. It seems the Rangers are just being cautious with the right-hander as he works his way back from Tommy John surgery. Darvish threw his first live session less than 10 days ago.
