While I wouldn’t normally think much of the leak that a federal grand jury has been convened as the government decides whether or not to indict Roger Clemens for perjury, this case may have some ramifications for the 2009 Yankees. As ESPN’s investigative reporter Mike Fish explains, Andy Pettitte could very well see himself dragged back into court to testify in front of the grand jury. While the Yanks and Pettitte are at a contractual impasse right now, this news will not be good for the Pettitte camp.
