Marlins president of baseball operations Larry Beinfest said Wednesday in a radio interview that when it comes to speculation about his future with the club, he’s fair game.

“When you sign up for this job and you don’t win, you know you can be in the crosshairs and you can lose your job. That’s just the way it is,” Beinfest told 790 The Ticket hosts Marc Hochman and Jonathan Zaslow. “The blame and disappointment and all those things fall squarely on my shoulders, and I fully understand that.”

Speculation is growing that Beinfest, who is under contract through 2015, could either lose his job or be reassigned to a new position by Marlins owner Jeffrey Loria.

“When you don’t win, you’re open to scrutiny, both publicly and internally, and that’s exactly what’s going on, and it’s not unexpected,” Beinfest said.

When Loria was asked about Beinfest’s job security earlier in the week, he said the question was “unfair” and did not elaborate.

Beinfest said during Wednesday’s radio show that the only thing he can worry about is the team’s performance.

You can “worry about things you can control, and obviously the control part of this for me would be to win more games and to do a better job and putting the organization in a position to win and, hopefully, play in October,” Beinfest said. “And that didn’t happen.”

Surprising call

It might have been the moment that relief pitcher A.J. Ramos had been waiting for for years, but when the rookie heard that he was about to enter his first major-league game Tuesday night, Ramos was confused.

“All I heard [from bullpen coach Reid Cornelius] was ‘Ra-’ and I was like, ‘Is that me?’ ” Ramos said. “He said: ‘You don’t know your name anymore?’ I was a little surprised.”

Matched up against the heart of the Brewers order — Rickie Weeks, Ryan Braun and Aramis Ramirez — Ramos struck out the side, the first Marlins pitcher ever to do so in his debut.

“You know how people say don’t look down? Well, I didn’t look up,” Ramos said. “I just made sure to keep my brim level where the catcher was and not to wander off.”

Manager Ozzie Guillen said he was “impressed” and that he hoped to use the rookie a lot in the final month of the season.

Stanton No fluke

Even though he has missed a month of the season with an injury, Giancarlo Stanton showed that last year’s 34-home run season was no fluke.

Stanton’s 30th of the year Tuesday came in just his 382nd at-bat, leaving fans to wonder what his total would be if he had not been on the DL in July.

Guillen said he does not want Stanton to focus on hitting home runs.

“[He should] just stay with 35 home runs,” Guillen said. “I don’t want this kid to all of a sudden turn around and be a 50-home run hitter and hit .210.”

Gary Sheffield’s club record of 42 homers in a season appears out of reach for Stanton, but he could soon break his personal record.
