Manager Craig Counsell revealed Monday that Perdomo tested positive for COVID-19 prior to the start of the Brewers' summer camp last week, Adam McCalvy of MLB.com reports.
Perdomo is currently asymptomatic, but he'll need to self-isolate and pass two COVID-19 tests before he's allowed to join the team. Though he was one of only four players on Milwaukee's 40-man roster who wasn't included in the initial club's 60-man roster pool released June 29, Perdomo was expected to report to the Brewers' alternative training site for summer camp.
