The Pirates and Yankees have agreed to a trade that would send A.J. Burnett to Pittsburgh, according to Major League sources. The agreement was submitted to the commissioner's office for approval on Friday. The Pirates will send right-handed reliever Diego Moreno and outfielder Exicardo Cayones to New York, according to sources. Approval is needed because of the money involved. The Pirates will pay $13 million of the $31.1 million remaining on Burnett's contract.
