Major League Baseball has called for Alex Rodriguez's attorney to show his hand -- and may have raised the stakes in the process.

MLB executive VP Robert Manfred in a letter revealed to attorney Joseph Tacopina during a nationally broadcast TV interview Monday morning agreed to waive the confidentiality clause written into the league's drug-testing agreement with the players' association as Tacopina had suggested would be a viable course of action.

But Manfred didn't stop at drug-testing information suggesting the remainder of evidence in the Biogenesis case as it concerns Rodriguez could be released for public consumption including "all documents records communications text messages and instant messages relating to Rodriguez's treatment by Anthony Bosch."

MLB sent the letter to the "Today Show" overnight and host Matt Lauer presented it to Tacopina during the in-person interview before asking the attorney if he would sign it.

"Listen we would love nothing more than to be able to discuss the testing history the scientific evidence and the tests of Alex Rodriguez under this JDA drug program nothing more" Tacopina said in response.

Tacopina later issued a written statement in which he called the letter "a publicity stunt."

"Such a waiver would require PA to be party of the agreement and signatures" Tacopina said in the statement referring to the players' union. "Nothing but a trap hoping I would sign knowing that I couldn't and in fact would have me breaching the JDA agreement."
