Treinen has been on the injured list since June 20 while recovering from right elbow inflammation, and he was able to face live hitters July 29. The 38-year-old will still be eligible to be activated from the IL late next week, though he will likely require a multi-outing minor-league rehab assignment, making a return in late August or early September more likely. In a corresponding move, Blake Snell (elbow) was activated from the 60-day IL on Tuesday.

Treinen landed on the injured list in late June due to right elbow inflammation, but the good news was that an MRI did not show signs of structural damage. He was cleared to play catch before the All-Star break and is ready to take the next step in his rehab by throwing off a mound. The Dodgers should have a better sense of Treinen's recovery timeline once the veteran right-hander is cleared to embark on a rehab assignment.
