This week's Pittsburgh Pirates-St. Louis Cardinals series has been postponed because of the coronavirus.

The clubs were scheduled to play Monday through Wednesday in St. Louis.

Major League Baseball said Sunday night that the league and the Cardinals "believe it is prudent to conduct additional testing while players and staff are quarantined before the team returns to play."

The Cardinals' series against the Chicago Cubs this weekend was also postponed after two players and one staff member tested positive for the coronavirus from samples collected over the previous two days.

St. Louis has not played since July 30 and have had 13 games scrapped.
