MIAMI (AP) ― Perched atop the Miami Marlins’ multicolored, provocative home-run sculpture is a blue marlin, poised for splashdown whenever the home team hits one out.

Call the artwork what you will ― gaudy, goofy, grotesque, great ― but there’s no denying it’s new. For the Marlins, that’s what this season is all about.

Long overlooked and underfunded, they’ve become a big-spending, attention-grabbing team as they open the season at home Wednesday night against the World Series champion St. Louis Cardinals.

The pop-art sculpture, futuristic ballpark, brisk ticket sales, team name, uniforms, celebrity manager, All-Star shortstop, All-Star left-hander, All-Star closer and starry-eyed optimism: all new.

With the roster significantly upgraded, the Marlins predict they’ll contend for the NL East title ― and more.

“We expect to win,” new shortstop Jose Reyes says. “The kind of club we have, we’re going to compete, no doubt.”

When ace Josh Johnson throws the first pitch in the new ballpark to Rafael Furcal, the Marlins will begin trying to supplant the Cardinals, who mounted an improbable late-season charge to the World Series title.

But like the Marlins, the 2012 Cardinals have a new look. Slugger Albert Pujols and manager Tony La Russa are gone and postseason star Chris Carpenter is hurt, so Kyle Lohse will start the opener. But right-hander Adam Wainwright is back from elbow surgery, Matt Holliday and Lance Berkman remain in the heart of the order, and the addition of outfielder Carlos Beltran is cause for encouragement.

“Their lineup is still stacked,” Johnson says.

Plus, only one team has a chance to repeat as the World Series champion, and baseball-crazy St. Louis is always eager for a season to start.

“There’s a buzz in every home opener,” rookie manager Mike Matheny says. “The buzz in our place is ridiculous.”

While the Cardinals will wait until April 13 to play a home game, outfielder Jon Jay is especially excited about the road opener. The Miami native attended Marlins games as a youngster when they played in the Dolphins’ stadium, so he can appreciate the new ballpark.

“To be able to play the first game there, it’s something I am going to remember forever,” he says. “The Dolphins’ stadium wasn’t really a baseball ballpark. It’s going to be nice for the community to have a real baseball park.”

The centerpiece is beyond the center-field wall ― a 73-foot-tall kaleidoscopic sculpture that will launch into animation when the home team hits a home run. Conceived by team owner Jeffrey Loria, a New York art dealer, the work has drawn decidedly mixed reviews.

“There’s a little controversy about whether people are going to like it,” says slugger Giancarlo Stanton, the player most likely to put the thing in motion. “They might not want me to do it. Everyone is saying it’s circusy.”

New closer Heath Bell dislikes homers but loves the sculpture.

“It’s colorful and shiny and awesome-looking, kind of like Miami,” he says. “You definitely won’t see that anywhere else. It’s straight Miami. We’re not dull; we’re flashy, colorful, lively, exciting.”

The team’s new rainbow logo fits with that premise. So does the matching orange-dyed hair Reyes and third baseman Hanley Ramirez now sport.

Fans seem captivated, at least for the moment, and the Marlins anticipate sellout crowds nearly nightly this year in their cozy 36,000-seat home. Heat and rain will no longer be a deterrent, thanks to air conditioning and a retractable roof that gives the ballpark an ultramodern appearance.
