Is there now another controversy brewing for a Boston professional sports team?

According to the New York Times, Yankees General Manager Brian Cashman submitted a formal complaint with the MLB office about the Sox stealing signs during a three game series two weeks ago at Fenway Park.  The article states that the Yankees sent videos of the Boston team stealing hand signals and then using a system involving an Apple iWatch.

The MLB has yet to comment on the claim and Red Sox manager John Farrell, along with other Sox coaches, did not comment on the matter, though Farrell was not aware of the use of sign stealing messages according to the reports.
