What has moving to Miami brought the Marlins? About 100 extra fans per game.

That’s the current gap between this year’s attendance and the average gate count for the Marlins’ last season at Sun Life Stadium the football field that owner Jeffrey Loria blamed for the team’s long-standing attendance and revenue woes.

Those problems ended up following Loria to the government-owned Marlins Park which is on track to face the worst fan rejection of a new baseball stadium in at least a generation. [Click here for an interactive chart on just how poorly Marlins Park is faring as a new baseball stadium.]

“Usually you have a honeymoon effect” said J.C. Bradbury a sports-science professor at Kennesaw State University in Atlanta who studies the business side of baseball. “It’s hard to have that when the fans are predisposed not to like you.”

Attendance for the Marlins hit a 15-year high with the opening of the 36000-seat Marlins Park last year despite lingering ire over Miami and Miami-Dade picking up most of the $634 million construction tab. But the gains didn’t last long. On the heels of a losing season Loria slashed the team’s payroll by $60 million and traded most of the star players. Sales of season tickets plunged 60 percent and the Marlins became the only Major League franchise to turn to Groupon to fill seats on Opening Day in April.

“I obviously still feel tremendously sorry about what happened last year” said Marlins president David Samson. “The goal we have with our fans every day is to get them to the point when they say ‘I remember when — I remember when I was so unhappy with the team. But now it’s a love affair.’ ”

At the moment the Marlins have the worst attendance in baseball at about 17830 people per game according to a ranking on espn.com. That amounts to an average sales drop of 10400 tickets from the 2012 inaugural season — a 37 percent decline.

Using attendance figures from the 1980s on posted at baseball-reference.com The Miami Herald compared the ongoing 2013 season at Marlins Park to the second year of every new stadium built since 1989.
