The New York Mets of Major League Baseball (MLB) have entered into a new partnership with sportswear and apparel company New Balance.

The deal, described by the team as ‘long-term’, sees the Boston-based brand become the official footwear and apparel partner of the Mets and their Citi Field ballpark.

While financial terms of the deal have not been released, it has been announced that, from 2018 onwards, New Balance will have permanent signage below the venue’s scoreboard - above a spectator section known as Shea Bridge - as well as a presence on its exterior and also at First Data Field, the Mets’ spring training home in Port St. Lucie, Florida.

New Balance will also kit out staff at certain events held at Citi Field, supplying them with polo shirts, shoes and jackets, and provide footwear to the Mets’ mascots, Mr. Met and Mrs. Met.

Besides the signage and supply components of the deal, the Mets and New Balance will also work together on various marketing and community initiatives over the course of their partnership.

“We are excited to join with New Balance as we align our brand with one of the most popular athletic brands in the world," said Mets chief operating officer Jeff Wilpon.

"Like the Mets, New Balance has a very loyal fan base, and we are proud to work with them in a variety of ways that implement marketing and community programs at Citi Field and in the New York region.”
