The colorful, futuristically built new home of the Marlins features a 75-foot home run structure beyond the wall in left-center field. It will go off only when a Miami player hits a home run.
Initially, the mechanical display, which will have spinning, splashing marlins as well as water spraying, was to be activated on Sunday for the Marlins-Yankees expedition, but the club announced a change of schedule on Sunday.
Instead, the sculpture will make its debut on Opening Night, which is Wednesday, when the Marlins face the Cardinals in a game that will be televised nationally on ESPN.
Marlins owner Jeffrey Loria, an art dealer, put artistic touches throughout the ballpark, which holds 37,000 people.
"The owner likes it," Guillen said. "I think it's pretty cool. I hope we make those marlins splash a lot. I hope we make those marlins drown, for as many times as they are going to be diving in."
