Union takes swing

HASN’T A-Rod suffered enough?

The Major League Baseball Players Association blasted MLB executive Rob Manfred Sunday for “publicly piling on” in a bombshell “60 Minutes” report that painted Alex Rodriguez as an inveterate doper the day after an arbitrator issued a historic 162-game drug ban against the disgraced superstar — even though Rodriguez’s lawyer also appeared on the show.

The union issued a statement on Sunday that said Manfred, MLB’s chief operating officer, had violated the confidentiality provision of baseball’s Joint Drug Agreement and undermined the integrity of the arbitration process by appearing on the CBS news magazine show. The Players Association said it would consider “all legal options to remedy any breaches” committed by baseball officials.

“It is unfortunate that Major League Baseball apparently lacks faith in the integrity and finality of the arbitrator’s decision and our Joint Drug Agreement, such that it could not resist the temptation to publicly pile-on against Alex Rodriguez,” the union said.

“It is equally troubling that the MLB-appointed panel arbitrator (Manfred) will himself be appearing in the ‘60 Minutes’ segment, and that Tony Bosch, MLB’s principal witness, is appearing on the program with MLB’s blessing.”
