MIAMI -- Marlins manager Ozzie Guillen isn't a big art aficionado, but he likes what he sees at Marlins Park.

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."

Marlins had tough roster decisions to make

MIAMI -- As a final warmup for the regular season, the Marlins are facing the Yankees in two exhibition games at Marlins Park.

So Saturday officially closed out the club's six-week stay at the Roger Dean Stadium complex in Jupiter, Fla.

Manager Ozzie Guillen was pleased with how the camp went in Jupiter, and noted that trimming down the roster was tough, because a number of players made strong cases to make the team. Instead, they will open in the Minor Leagues, as the big league club prepares for Wednesday's Opening Night against the Cardinals in Miami.

"I think everybody is healthy, and good enough to get to the start of the season," Guillen said. "We still have two more games. It was a very nice spring. I think it was better than I thought."

The team is going through a transition, dealing with a new manager, staff and preparing to move into a new ballpark.

"There was a lot of new things for everyone," said Guillen, in Miami now after spending eight seasons managing the Chiacgo White Sox. "New coaching staff. New things with myself, and the players. It was a great chance to get to know each other, and a great chance to show how we're going to play.

"It was a fun Spring Training. I think we've played good. I think we played better than the win/loss record."

The roster is all but officially announced. Austin Kearns had his contract selected on Saturday, and he will make the team as a reserve outfielder and right-handed bat off the bench.

Donnie Murphy will assume the utility infielder role.

Murphy gets the nod over prospect Donovan Solano, who had a sensational Spring Training. Solano will head to Triple-A New Orleans.

"[Guillen] was mad," said Solano, who hit .410 in 39 at-bats in the spring. "I could tell he didn't want to tell me that. But that's OK. I'm happy because I got the opportunity. I had a good experience. The same work I did this spring, I want to put into the season."

Reliever Chad Gaudin is making the club as a long reliever.

Guillen noted that Wade LeBlanc and Gary Glover each had great camps, but both are starting off in New Orleans.

"This was the hardest Spring Training in having to pick the guys," Guillen said. "What do we tell Glover? How bad he pitched? LeBlanc? We sent Solano down. What do we tell Solano? He had the best camp.

"The meeting [to pick the squad] was a little intense. Everybody who was sent down from the last week until now, it was a very tough move. I think they deserved to be on the big league team also."

On Sunday, the Marlins displayed for the first time their red-orange jerseys, which they plan to wear at home on Sundays. During Spring Training, the team wore mostly black or white jerseys.

Wet infield only real hiccup on Sunday

MIAMI -- A storm on Saturday dropped enough water on the field at Marlins Park to create some commotion on Sunday afternoon.

Under a closed roof on Sunday, the Yankees beat the Marlins, 10-8, in the first of two exhibition games at Miami's new ballpark.

But because of wet conditions, the infield was an issue for a number of players.

"It was tough," Marlins shortstop Jose Reyes said. "It was soft. It was wet. It was hard to play on it. It was a little bit dangerous. I think they forgot to close the roof. I don't know."

Because the field has natural grass, the roof remains open most days to allow the sunshine.

It takes about 14 minutes to close the roof. If a storm passes through quickly, it can douse the field for a few minutes.

The players noticed on Sunday.

"That infield was like running in sand," said Nick Swisher of the Yankees. "I think they left the roof open last night. It rained. That's why you didn't see many guys running very hard on the bases. This is not the type of game you want to bust yourself up on something like that. I'm sure tomorrow they'll have it ready to go."

Marlins first baseman Gaby Sanchez praised the grounds crew for making the field playable.

"It was definitely real wet out there," Sanchez said. "The grounds crew did a great job to make the field playable for us -- kudos to them for keeping it in playing condition."

A-Rod impressed by Marlins' new home

MIAMI -- The first impression is a good one for Yankees All-Star Alex Rodriguez.

A Miami native, Rodriguez is impressed with Marlins Park and all of its color and glitter.

After 19 years of sharing Sun Life Stadium with the Miami Dolphins, Rodriguez says the Marlins' new home will change the perception of the franchise.

"Without question. This is kind of like, 'Hello, Major League Baseball, we're here,'" Rodriguez said. "[Owner] Jeff Loria and his staff worked very hard with the city of Miami. I'll tell you, I get chills. I'm a little emotional because I'm right down the street.

"I get to share this with my family and friends today, my two daughters will be here. They're super excited. Look, we know what Yankee Stadium means to us in New York; it means the world. It has been a big success for us and I really hope that [Marlins Park is] a huge success, not only for Major League Baseball but for Jeff and the Marlins."
