Detmers (COVID-19) threw a bullpen session in San Diego on Wednesday, MLB.com reports.

EDGE Analysis

Detmers recently confirmed that his placement on the injured list in late August was due to a positive COVID-19 test, but the rookie appears to have recovered and will now build up with an eye toward a return. He isn't stretched out to start, however, and could move to a relief role given that he'll almost certainly be on a limited pitch count upon rejoining the big club.
