This is a smoking gun? What are they smoking?

Attorneys for Alex Rodriguez filed an amended complaint in his lawsuit against Major League Baseball on Tuesday that claims Bud Selig chose to "hide" in Milwaukee rather than testify at the scandal-stained superstar's appeal of his 211-game doping suspension last week.

They claim the baseball commissioner's "cowardly stance" is consistent with his highly inappropriate past conduct – and as proof, they included a photo of Selig posing with a young fan wearing a Cincinnati Reds hat and an "A-Roid" T-shirt.

"One cannot imagine the commissioner of any other professional sport - or indeed the CEO of any business - doing something similar with respect to one of his or her players or employees," Team A-Rod said in the papers filed in Manhattan federal court.

The 33-page amended complaint says that Selig "lacked the courage" to come to New York and explain why he slapped Rodriguez with an unprecedented penalty and defend the conduct of MLB investigators during baseball's Biogenesis investigation.

"His silence on these issues speaks volumes and leads to only one logical conclusion – his actions and those of the MLB personnel he controls, were aimed at destroying the reputation, career and business prospects of Alex Rodriguez," says the filing, which most rehashes allegations from an earlier version of A-Rod's lawsuit against Major League Baseball.

Rodriguez and his attorneys believe Selig should have been required to take the witness stand in the arbitration hearing and explain how he decided to suspend the embattled player's unprecedented penalty. Rodriguez stormed out of the hearing last week after arbitrator Fredric Horowitz ruled that Selig did not have to testify because MLB chief operating officer Rob Manfred taken the witness stand on behalf of baseball.

The commissioner has never testified during a doping arbitration since MLB and the Players Association approved their joint drug agreement in 2002. An MLB spokesman declined to comment on the amended complaint.

The papers repeat allegations Rodriguez's attorneys have already made in earlier court filings and in press interviews. It claims that MLB practiced "vigilante justice" in its investigation into Rodriguez and that baseball officials knew documents they had purchased had been stolen. The complaint also claims that MLB violated the drug agreement's confidentiality clause by leaking information to the Daily News and other media outlets.

The court papers refer to numerous affidavits signed by witnesses who claim they witnessed inappropriate behavior by MLB officials and investigators – but it does not explain why any of those witnesses were not called to testify in the arbitration hearing, which 52 days concluded last week after 12 sessions. Rodriguez's attorneys only called a handful of witnesses, including Yankee president Randy Levine, before concluding his defense last week.
