Friday's matinee in Milwaukee between the St. Louis Cardinals and Brewers at Miller Park was postponed hours before the game due to positive COVID-19 tests, MLB Network and baseball insider Jon Heyman reported.
The Cardinals were scheduled to visit the Brewers for Milwaukee's home opener but instead will isolate at the team's hotel.
Heyman reported Friday morning the "Cardinals had positive tests, forcing postponement."
The Cardinals, per the St. Louis Post-Dispatch, did not go to Miller Park. The team was off Thursday.
However, MLB Network's Joel Sherman reported the players likely were tested while in Minnesota at the conclusion of the series against the Twins. That could jeopardize games this weekend for the Twins and Cleveland Indians, who played Minnesota on Thursday.
In addition to the National League Central game being scratched from the Friday slate, originally scheduled games involving the Philadelphia Phillies, Miami Marlins, Washington Nationals and Toronto Blue Jays already were postponed because of COVID-19 concerns.
Staff ace Jack Flaherty (1-0, 2.57 ERA), who earned a 5-4 victory over Pittsburgh on Opening Day, was scheduled to start for St. Louis against veteran left-hander Brett Anderson.
Flaherty blanked the Pirates for six innings before allowing two runs in the seventh.
