There's no kerfuffle this year, as the Mets received permission to wear first-responder hats during batting practice and the national anthem on Sept. 11. You may remember last year the Mets were denied permission to wear the hats on the 10th anniversary of the attacks on New York and Washington, D.C.

The Mets will wear hats from various city agencies during batting practice before their game against the Nationals. 

With an off day on Thursday, the Mets' Mike Baxter, Dillon Gee and Bobby Parnell visited the 9/11 Memorial, as well as FDNY Engine 10, Ladder 10 on Liberty Street across from the World Trade Center site.

The team also announce the Gies family will throw out the first pitch on Sept. 11. Ronnie Gies, a New York fireman, died on Sept. 11, 2001. His son, Ronnie, is a member of the FDNY, while another of his sons, Bobby, recently took the test to become a fireman.

"I always tried to be at Shea or Citi Field on 9/11, because those were always our family's fondest memories," Carol Gies, Ronnie's widow, said in a statement released by the team. "My husband was a gigantic Mets fan, as is my entire family. We all think happy thoughts when we are at a Mets game."
