We must wait one more day for the full details of the Marlins’ 2020 regular season schedule, but the Phillies have been identified by Craig Mish as their first opponent:
The Miami Marlins will open up the 2020 Baseball season on the road - Friday July 24th taking on the Philadelphia Phillies, per sources. MLB releases the full schedule on Monday.

The length of the series is unclear. It’s typical for MLB teams to play three-game sets on Fridays/Saturdays/Sundays, but perhaps the league will opt for longer series in 2020 to minimize the total number of flights in the midst of COVID-19.
