Neither the Marlin or Brave series were scheduled that way. But you are right, that used to be the common practice.
Yeah, I found that odd that the Marlins series was like that. But it may have been a choice based upon it being in Florida, and the fact that they knew they wouldn't come close to a sell out. The Braves/Phillies series did have the day off after the opener. It may be that certain cities base it on likelihood of weather issues.
