MIAMI -- The Marlins project to have a solid 15,000 season tickets sold by Opening Day.

If momentum keeps building, they might be in position to cap their season tickets, to make room for groups and people traveling into Miami who want to attend games.

The Marlins open on April 4 against the Cardinals in a game that will be nationally televised.

In their artistically structured stadium, which has a capacity of 37,000, the Marlins plan on selling season ticket packages a month or two after the season starts.

"We've never done this, but we project that we will be selling season tickets through May, which is a nice thing that we were never able to do," Samson said.

There is high demand in the team's inaugural year at Marlins Park.

"For us, we would probably cap it at 18,000, and then start a waiting list, because there is such a demand from groups and for people coming from Naples and the Keys," Samson said. "Tickets are going so well. That's part of the supply and demand. We would never want to sell 35,000 season tickets. We couldn't or wouldn't."

The thought of actually turning away potential season-ticket holders is something entirely new for the franchise, which had sparse crowds at Sun Life Stadium.

Samson couldn't help but laugh at their season ticket total of last year.

"We did a calculation, and we were No. 125 in season tickets," Samson said. "I'm counting Minor League teams, hockey teams, [etc.]."

Asked if they were last in the Major Leagues, Samson quipped: "We weren't last. Last was so far ahead of us. We were three standard deviations from last, which is the best way to say that."

Dominguez to miss a few days

MIAMI -- A bad-hop bouncer struck Marlins third-base prospect Matt Dominguez in the face on Tuesday afternoon. But it appears the 22-year-old dodged a serious injury.

Initially, manager Ozzie Guillen thought Dominguez had sustained broken bones. Instead, he is being treated for a big bruise to the right side of his face.

The injury occurred in the afternoon against the Tigers at Roger Dean Stadium. But early in the evening, Guillen was encouraged that Dominguez was going to be fine.

The team hopes Dominguez only misses a few games. Dominguez was scheduled to play at Marlins Park on Wednesday night against Florida International University. He will remain in Jupiter for treatment.

"When I was there, I thought everything in his face was broken," Guillen said shortly before the Marlins faced the University of Miami at Marlins Park. "Thank God, it didn't happen. I was thought it was uglier. He got lucky."

Roof closes before first pitch

MIAMI -- The Marlins were planning on keeping the roof open on Tuesday night in their exhibition against the University of Miami, but about 30 minutes before the first pitch, the winds kicked up and threatening clouds hovered over Marlins Park.

The roof closed in less than 14 minutes, or roughly 6:55 p.m. ET, before the scheduled 7:10 start.

Had the conditions been favorable, the hope was to have the roof open, but the glass wall in left shut. When the wall and roof are open, it provides a clear view to downtown Miami.

"Having the windows open adds more room," Marlins president David Samson said. "It's an interesting dynamic. With the wind blowing in, depending on who you ask, it's a pitchers' or hitters' park."

The Marlins initially planned on having the roof open on Tuesday and Wednesday night.

But it was decided to shut the roof on Wednesday against Florida International University, because rain is in the forecast. The team also wants to see how the conditions play with the roof open and shut.

For Opening Night on April 4 against the Cardinals, the Marlins hope to have the roof and left-field area wall both open. But that will be determined on the weather, including wind conditions. Any wind that approaches 30 mph would require the wall to be closed.

Samson said that during the season, he doesn't anticipate the roof being open and then shutting when the game is actually played.

On days the roof is expected to be closed, in the dog days of summer, the roof will close at 4 p.m. ET daily and remain shut. It will stay open in the day time to provide sunlight for the Celebration Bermudagrass.
