Polanco was placed on the injured list Tuesday for unspecified reasons.
The Pirates announced the move without an injury designation, so it's possible Polanco has been placed on the COVID-19 injured list. The 29-year-old will be eligible to return once he clears league protocols if that is indeed the case. Regardless, he should be considered out indefinitely until any specifics are provided. Hunter Owen had his contract selected by the Pirates in a corresponding move.
