As the New York Mets try to improve their fortunes on the field, they're reportedly losing more money off it.

According to Newsday, the team's ballpark-related revenue fell more than $8 million from 2011 to just under $119 million this year. Additionally, it's down more than $61 million from 2009 when Citi Field opened.

The paper also says revenue from Citi Field's premium seats fell nearly $6.5 million from 2011.

Experts blame the drop in premium ticket revenue on lower prices and the Mets' poor showing in the second half of this season.

The paper says Citi Field's revenue, including premium seats, concessions and parking has dropped off 43 percent since 2009.

The Mets are raising overall ticket prices next season for the first time since the ballpark opened.
