Carter's wife, Sandy, son, D.J., and daughters, Kimmy and Christy, will be on the field with their families during a moment of silence and ceremonial first pitch in the catcher's honor. Carter passed away Feb. 16 following a 10-month battle with brain cancer.
"Our family is so honored to be part of the Mets' Opening Day at Citi Field," Sandy Carter said. "It will be an incredible experience for us to celebrate Gary's legacy by having our family throw out the first pitch. The Mets and the fans of New York always had a special place in Gary's heart and that admiration will live on in our hearts for years to come. Thanks to the Wilpon family and the entire Mets organization for making this possible."
"We are thrilled that the Carters will be with us," Mets COO Jeff Wilpon said. "On Opening Day, Mets fans will have the chance to pay their respects and remember all of his accomplishments."
Carter spent five of his 19 big league seasons with the Mets, most famously playing a significant role in their 1986 World Series title. He was inducted into the Mets Hall of Fame in 2001 and the National Baseball Hall of Fame in 2003.
The Mets have already begun wearing a patch on their right uniform sleeve to honor Carter, featuring a black home plate with the words "KID 8" in white lettering, a reference to Carter's nickname and uniform number.
