Marte (undisclosed) tossed a bullpen session in San Diego on Wednesday and could be activated in the coming days, per MLB.com.
The right-hander has been on the injured list since Aug. 22, and though a reason was never announced, it's likely that he has been navigating COVID-19 protocols. While he's pitched in only one game for the Angels this season, Marte could be given a spot in the bullpen upon his return.
