The mystique of Marlins Park has the baseball world befuddled.

How to explain why the Marlins have turned virtually unbeatable at home when they rarely win anywhere else?

After Tuesday's 3-0 win over the Mets, they are 7-1 on this homestand with a matinee finale remaining Wednesday, and 16-5 at home this season.

The Braves' suspicions last week that their signs were being stolen prompted the Mets to vary theirs in this three-game series, just to be safe. Even radio host Jim Rome asked Marlins manager Mike Redmond about the conspiracy theory on his nationally syndicated show Tuesday.

"Maybe it's those power fans that we turn on when we're hitting," Redmond joked before Tuesday's game, recalling a similar theory about the air-conditioning in the Metrodome in Minnesota when he played for the Twins.

In the series-clinching victory against the Mets, it was a much more mundane explanation. They got early offense from their most productive hitters — hot-hitting Casey McGehee drove in two runs — and an efficient command performance from right-hander Henderson Alvarez.
