In what should be the first of a several moves they make this week before the start of the regular season, the Pirates have transferred Gregory Polanco to the 10-day injured list and selected the contract of left-handed pitcher Robbie Erlin.
Neither move is particularly surprising. Polanco has been absent from summer camp since July 14, with Derek Shelton confirming that it was because he tested positive for COVID-19. Polanco gave his consent to share his test results.
He will need to pass two consecutive tests before he is allowed to rejoin the team.
