The Marlins-Mariners games for June 24-26 were originally to be in Florida, but due to a U2 concert they were moved. The games are played in Seattle without the DH and with the Marlins batting last. For purposes of splits and Home-Road records etc. We are treating the Mariners as the home team. We know the arguments the other way, but this is how we've chosen to handle these and previous games played under similar conditions.
Way back when, the home team actually had the option of batting first and did on occasion choose to do so, so this isn't without historical precedence.
The funny aspect of MLB's contortion to give the Marlins "home-field" is that I know of at least one study that shows that batting last is of no particular advantage. All of the information the offense gets to act on is similarly acted on by the defense, so at neutral sites the home team wins 50% of the games.
