It is relevant for understanding how much money he was

walking away from, which is far less than he would have been walking away from in 2019 (that's separate of the contract agreement the Mets and Cespedes came to after the Mets threatened legal action, but that's another story). Player salaries are all out there on the Internet. I am not terribly sympathetic about Cespedes because he went AWOL on the Mets (unless someone wasn't checking their messages) and they had to put out this "We don't know where he is" announcement earlier today.

A better question to ask Nightengale is why he didn't have a similar tweet about Lorenzo Cain opting out and how much money he was walking away from, which is certainly higher (it's $5.92 million, per Yahoo).

Back to your original question: he didn't tweet out Murphy's salary. 8^)
