Yanks hand-deliver A-Rod a letter

NEW YORK -- Prior to Alex Rodriguez's first home game of the season, the New York Yankees hand-delivered a letter to A-Rod in the clubhouse, officially informing him he will be disciplined for seeking a second opinion on an injury without club approval, sources said.

Rodriguez and the Yankees fought publicly late in July over the health of his quadriceps. Without officially informing the team, Rodriguez had orthopedic surgeon Dr. Michael Gross of Hackensack University Medical Center examine his MRI. Dr. Gross then did a media tour.

Sources indicated then that the Yankees likely would discipline A-Rod, but didn't inform him until right before his 2013 home debut Friday night. The letter did not specify the exact nature of the discipline, a source said.

The Yankees will cite Article XII, Paragraph D of the collective bargaining agreement that a "player shall inform a team in writing" before seeking a second opinion.

The day before Gross' media tour, Rodriguez called team president Randy Levine, sources said, and told him he did not trust the Yankees' medical team. Rodriguez, a source said, felt they misdiagnosed his hip during last October's playoffs. Now, with Rodriguez back on the field, the Yankees reminded him before his home debut that he must follow the proper protocol.

Rodriguez, who is appealing his 211-game suspension for violating Major League Baseball's drug policy, did not speak to reporters Friday.

The Yankees also sent out an official letter to Francisco Cervelli, telling him he will be disciplined for failing to report to work prior to the announcement of his 50-game suspension, a source said.

Rodriguez entered Friday night with the uncertainty of how the home fans would react to him. During the Yankees' 10-inning win against the Detroit Tigers, he received more cheers than boos upon his introduction, but went 0-for-4 with three strikeouts, which turned the crowd negative.
