The St. Louis Cardinals' four-game series at the Detroit Tigers has been postponed.

"The Cardinals have had 13 members of the organization test positive for COVID-19 in the last week, including seven players and six staff members," the league said in a statement. "The Club, which has been in quarantine since Thursday, will stay in Milwaukee and their personnel will continue to be tested daily. The tentative plan is for the team to resume its regular schedule on Friday against the Chicago Cubs in St. Louis."

After one player and three staff members tested positive Saturday, the Cardinals' three-game weekend series with Milwaukee was postponed.
