DETROIT, Mich. (WLNS) – Major League Baseball announced Monday that the four-game series between the Detroit Tigers and St. Louis Cardinals scheduled to begin on Tuesday at Comerica Park has been postponed.

The series between the Detroit Tigers and the St. Louis Cardinals was supposed to be from Tuesday, August 4th through Thursday, August 6th.

The Tigers will hold workouts throughout the week before flying to Pittsburgh on Thursday, according to a statement by the Detroit Tigers.

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 team has been in quarantine since Thursday.

Four games between the Cardinals and Milwaukee Brewers were postponed this weekend because of the outbreak, according to reports from the Detroit Free Press.

The Cardinals and Brewers series included Sunday’s doubleheader which means one of the games in their originally scheduled three-game set was called off twice.

The Cardinals will stay in Milwaukee and 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, according to the MLB.

The 2020 MLB season is just more than a week old, yet the schedule continues to be altered due to COVID-19 cases across the league.

As of Monday, 18 different MLB games impacting a total of nine teams had been postponed due to COVID-19 cases, according to a report by CBS Sports.

MLB commissioner Rob Manfred reportedly told MLB Players Association union chief Tony Clark on Friday that coronavirus testing protocols need to be followed more closely and that more positive tests could see the league shut down as soon as early next week.
