On the 10th anniversary of September 11th, the Mets planned to wear caps honoring the NYPD, FDNY, and other first responders—just as they did during the emotional first game after baseball resumed in 2001. MLB said no way—because it had its own patriotic caps to sell.
When MLB got wind of the Mets' plan, they send out a memo reminding teams that only the official New Era American flag caps ($36.99 plus shipping and handling) were acceptable. Then during the game, after some Mets wore their first responder caps between innings, MLB sent employees into the dugout to take them away. This is our story from the morning after.
