The financial services company has signed a 20-year deal for more than $20 million per year. Citigroup has the ability to extend the deal for up to 35 years, according to reports. This deal is almost double the previous largest deal for the naming rights if a stadium; which was set by Reliant Energy when it agreed to pay $10 million a year for the National Football League's Houston Texans. The stadium is called Reliant Stadium and opened in 2002.

"We are proud to be a partner with a company that shares our values," said Fred Wilpon, CEO and chairman of the Mets. As part of the partnership, Citigroup and the Mets have given a significant donation to the Jackie Robinson Foundation. In the new stadium, the main entrance will be dedicated to Jackie Robinson. The rotunda, with the former Brooklyn Dodger's player's name, will include a statue of the man and the phrase, "A life is not important except for the impact it has on others lives."

Vice chairman of Citigroup Lou Kaden said there are three reasons the company decided to join forces with the Mets. "The first is we love New York. Secondly, we love the Mets; we think the value the Mets express on the field, off the field match the values we have and third, and in some ways most important, we have enormous regards for the Sterling family."
