Junis (hamstring) threw a bullpen session Tuesday, Alex Pavlovic of NBC Sports Bay Area reports.

EDGE Analysis

Junis was ruled out 4-to-6 weeks after suffering a Grade 2 hamstring strain in mid-June, and he's creeping closer to embarking on a minor-league rehab assignment. However, the 29-year-old will first need to advance to facing live batters, and it's unclear when he's expected to do so.
