Both teams were kept from playing games after a COVID-19 outbreak reportedly affected 20 individuals within the Marlins organization; Miami faced the Phillies in their season-opening series in Philadelphia.
The Phillies are scheduled to resume play against the New York Yankees in a four-game, home-and-home series. The teams will square off at Yankee Stadium on Aug. 3 and 4, with two games at Citizens Bank Park to follow on Aug. 5 and 6.
MLB plans to have the Marlins - who have been quarantined in Philadelphia since July 25 - play a four-game series against the Baltimore Orioles at Camden Yards from Aug. 4-6. One of those days will include a doubleheader, and the Marlins will be the home team for two of the contests.
Orioles manager Brandon Hyde isn't concerned about the visiting Marlins, provided the league has performed due diligence.
"We're trusting MLB, and I feel really strongly that we've followed the protocols so well here," Hyde said, according to Jon Meoli of the Baltimore Sun. "I know that MLB is on top of it. If they feel like they're comfortable with them playing here, I'm comfortable as well, just because I know how stringent our protocols are and how they're keeping the players' health and safety first for everybody."
Games between the Phillies and Marlins originally scheduled for Aug. 4-6 will be rescheduled for later dates, as will a game between the Yankees and Orioles set for Aug. 5.
Saturday's scheduled game between the St. Louis Cardinals and Milwaukee Brewers, meanwhile, has been postponed after two Cardinals players tested positive for COVID-19. Another player and multiple staff members may also be positive.
Additionally, a game between the Yankees and Tampa Bay Rays scheduled for Aug. 6 at Tropicana Field will be rescheduled as part of a doubleheader on Aug. 8.
