First Brian Cashman cursed out A-Rod and now he’s calling him out.

The Yankees general manager who last month publicly ordered the third baseman to “shut the f--- up” when he tweeted about being ready to play in games before being given the green light said Alex Rodriguez should file a grievance with the Major League Baseball Players Association if he really feels the Yankees are preventing him from playing by falsifying his medical condition regarding his strained left quadriceps muscle.

“The MRI is the MRI. It’s fact” Cashman said. “You can’t change the results of an MRI. We’re very comfortable with it and if anybody wants to utilize the process in place with the union go right ahead. It’s not something we’re afraid of.”

Apparently there is no such thing as a quiet day in Yankees Land as far Rodriguez — who injured the quad while rehabbing from offseason hip surgery — is concerned. But before Cashman met the media it appeared yesterday just might be one.

There were no conference calls radio interviews or second opinions regarding the much-talked-about quad. Cashman declined to comment on all other matters regarding Rodriguez such as going on WFAN without the team’s permission tweeting about his desired return and not following protocol when he got a second opinion on the quad which would violate the collective bargaining agreement.

The beleaguered third baseman on the verge of being suspended by Major League Baseball because of his alleged involvement in the Biogenesis performance-enhancing drug scandal arrived at the Yankees’ minor league complex at 10:30 a.m disappeared for three hours while undergoing treatment ran the recumbent bike and left without speaking to reporters. A Yankees employee even moved A-Rod’s Chevy Tahoe so he could try to avoid having his photo taken before driving off.
