A woman who says she is the former mistress of New York Yankees general manager Brian Cashman filed a petition saying that Cashman told her he intentionally misled federal investigators during the Roger Clemens investigation, reports USA Today.

Louise Neathway also says that Cashman knew of clubhouse steroid use by various Yankees players and was ambivalent to the use of performance enhancing drugs as long as nothing came back to the Yankees organization.

The petition also states Yankees third baseman Alex Rodriguez's new attorney, Joseph Tacopina, has a conflict of interest in Rodriguez's case because his partner, Stephen Turano, represents Neathway in New Jersey and knows of information from Neathway's relationship with Cashman that could bolster Rodriguez's case against the Yankees.

SI NOW:  Is there a conspiracy against A-Rod?

Neathway, 37,  faces 52 criminal charges include stalking, harassment, lying to a grand jury, criminal impersonation and grand larceny. Neathway faces deportation if she is found guilty.

She also allegedly threatened to shoot her former mother-in-law – a document stamped Nov. 29, 2012, states, "The defendant threatened to tell the press and Mr. Cashman's family, particularly his wife, that he and the defendant had had a sexual relationship, that she had become pregnant with, and aborted, his child, and that she had suffered a series of serious medical complications from the abortion that had required surgeries.
