It’s pretty clear from the images above that Charlie is wearing the gray Ireland National Baseball Team T-shirt with the official harp and baseball logo of Baseball Ireland. We can’t confirm or deny if Charlie Day bought the shirt from Amazon.com, but we do hope he leaves a great review!

We’re happy to welcome Charlie Kelly into the ranks of Irish Baseball fans and we’ll add Paddy’s Pub to the list of Irish pubs that support #IrishBaseball!

We aren’t sure exactly when the episode will air, but it will be sometime during the month of March in 2017.
