Missing a day of work without the permission of the New York Yankees could wind up costing Alex Rodriguez more than $150000.

Rodriguez who is currently playing pending appeal of the 211-game suspension handed to him by commissioner Bud Selig on Monday for violating baseball's drug policy was hand-delivered a letter written by Yankees general manager Brian Cashman before Friday night's game against the Detroit Tigers as first reported by ESPNNewYork.com's Andrew Marchand.

According to sources familiar with the letter's content the club reprimanded Rodriguez for his recent actions surrounding his rehab assignment. Those actions include seeking a second medical opinion without giving the Yankees prior notice and failing to show up at the ballpark on July 12 after meeting with MLB officials to discuss the evidence against him in baseball's investigation of the now-closed Biogenesis clinic suspected of being a source of illegal PEDs.

The Yankees have already fined Francisco Cervelli who accepted MLB's 50-game suspension for his involvement with Biogenesis the equivalent of one day's pay for failing to show up for treatment on his injured hand and shoulder on July 28. According to a club source Rodriguez likely would be fined accordingly for what the Yankees consider a similar offense.

Two sources who have seen the letter said part of it reads: "The club contemplates discipline for your most recent violation of the Collective Bargaining Agreement." Although no specific punishment is mentioned $153005 is equivalent to one day's pay [based on 183 days] under Rodriguez's contract which calls for him to earn $28 million for 2013.

According to a team source Cervelli failed to report to work or contact the team and had to be tracked down by a team trainer. Cervelli said he was "too stressed out" to come to the Yankees' developmental complex in Tampa Fla. after learning he was about to be suspended the source said.
