Embattled Yankees third baseman Alex Rodriguez unexpectedly showed up in studio for the New York based Mike Francesa's WFAN radio show Wednesday, hours after walking out of his appeals hearing in extreme anger.

Among the highlights:

•A-Rod said that he's done with the arbitration process unless commissioner Bud Selig shows up. He's extra angry that he missed his nine-year-old daughter's birthday Monday to be in the courtroom while Selig has refused to show up.

•Here's the major bombshell: A-Rod vehemently denies any wrongdoing in the case, including saying that he's not used PEDs at all since 2003. He also denies having leaked documents about Ryan Braun to Yahoo Sports, calling that accusation by MLB "laughable" and "disgusting." Finally, he denies any obstructing of justice during the course of this case, one of the several reasons given by Major League Baseball to give Rodriguez the biggest drug-related suspension of all-time.

•A-Rod's attorney said that if Selig does show up, Rodriguez will take the stand and testify Friday.

•MLB COO Rob Manfred told A-Rod that Selig not being there wasn't his decision, according to A-Rod.

•Biogenesis founder Anthony Bosch is "making a mockery of baseball" and working on a book deal, per A-Rod.

•A-Rod says that he's offered to meet in a coffee shop and discuss things with both Selig and Manfred "man to man" and the reply was each was "we don't want to see you." He says he was advised to take an attorney to the proposed meetings, but he declined because he just wanted to discuss things as grown ups.

•A-Rod also noted that "if it wasn't for my attorneys holding me back," he would have spoken out against MLB's treatment of him long ago.
