Saturday's game between the Cardinals and Brewers has been postponed after rapid COVID-19 tests indicated additional St. Louis members may have the virus.
The league has also postponed both legs of a doubleheader that was to take place on Sunday, according to ESPN's Jeff Passan.
The Cardinals will play next beginning on Tuesday, with four games in three days against the Tigers in Detroit. The teams will play a doubleheader on Wednesday, and each will be designated as the home team for two games, per ESPN's Jesse Rogers. The Brewers will continue with their schedule.
"After two Cardinals players tested positive, the entire team was tested in Milwaukee [Friday] using a rapid COVID-19 test and saliva samples also were sent to an MLB laboratory. The rapid tests indicated that one additional Cardinals player and multiple staff members may be positive," MLB said in a statement. "The results from the MLB PCR saliva tests will not be available until later in the day. Based on the results of the rapid tests conducted in Milwaukee, tonight’s scheduled game between the Milwaukee Brewers and the Cardinals at Miller Park has been postponed."
Friday's game between the Cardinals and Brewers was canceled in Milwaukee after two St. Louis players tested positive. Those two players were tested before the team's game Wednesday against the Twins, though they did not receive the results until late Thursday night—more than 24 hours later. The Cardinals were instructed to self-isolate in their hotel rooms until further notice while the team conducted rapid testing of the entire traveling party.
The cancelation continued a growing trend across MLB after the Marlins registered over a dozen positive COVID-19 tests this week. Miami's series vs. Philadelphia was postponed on Tuesday, with the Marlins slated to stay off the field until at least Aug 4.
The Phillies have not registered a positive test among their collection of players, though they will not play over the weekend after three staffers tested positive for COVID-19 during the week. However, MLB announced Saturday that two of those cases were false positives.
