The New York Yankees have traded reliever Adam Ottavino to the Boston Red Sox for a player to be named or cash.

New York was looking to reduce its luxury tax bill. They will send $850,000 to Boston to offset some of Ottavino's $8 million salary, according to a source.

This was just the second trade since 1987 between the rivals.

"I know it's the Yankees and I understand what that means and it's the most storied rivalry in sports," Red Sox chief baseball officer Chaim Bloom said. "But if we're not willing to do something that helps us because it also helps them, or worse, if we're worried that it might not go as we expect and it blows up in our faces and we looked at it, well, then, we're just playing scared, and we're not going to play scared."
