Perdomo (illness) was added to the Brewers' 60-man roster Thursday.
Perdomo tested positive for COVID-19 prior to the start of the Brewers' camp last week, but he'll get a chance to work at the team's alternate training site once he recovers. It's unclear whether the left-hander is symptomatic, but under MLB protocol, he'll need to undergo two negative tests prior to joining the team.
