Diaz (elbow) threw live batting practice Wednesday and is approaching a minor-league rehab assignment, per MLB.com.
The live BP was Diaz's second over a four-day span and marked another step forward in his recovery from the elbow surgery he underwent in late April. The expectation remains that Diaz will need to embark on a rehab stint before being activated from the 60-day IL, but even so he appears in line to return to the Dodgers' bullpen not long after the All-Star break.
