Alex Rodriguez's lawyers contacted the Major League Baseball Players Association to begin a grievance regarding their claims that the New York Yankees mishandled Rodriguez's medical treatment this season and last season, ESPN reported Sunday.
Rodriguez's lawyers claim the Yankees had Rodriguez play last October despite his bad hip. Perhaps more significantly, they accused Yankees president Randy Levine of telling a surgeon that it would be all right with Levine if Rodriguez never was able to play again.
Finally, the lawyers allege the Yankees prevented Rodriguez from playing this year with a Grade 1 quad strain even though Rodriguez said he was healthy enough to play.
According to the report, Levine told Rodriguez on Saturday to "put up or shut up," saying he would make Rodriguez's medical records public if A-Rod consented.
The lawyers' notification to the players' union represents the first official step toward having the complaint resolved by arbitrator Frederic Horowitz. Horowitz will also arbitrate Rodriguez's 211-game suspension, although that ruling is not expected to occur until November at the earliest.
Yankees general manager Brian Cashman also said that Rodriguez lied to him in July during another dispute about A-Rod's health.
The Yankees were holding Rodriguez out of games due to what they diagnosed as a quadriceps strain. Cashman said Rodriguez told him he wouldn't seek a second opinion, but days later, orthopedist Michael Gross said on the radio he viewed Rodriguez's medical tests and disagreed with the Yankees' diagnosis.
"I know that, at that moment in time, I was lied to," Cashman said.
Due to the contentious nature of the player's relationship with the team, Cashman said he is not speaking to Rodriguez beyond saying hello and goodbye.
