NEW YORK — Roger Clemens filed a defamation suit against former personal trainer Brian McNamee in Texas state court Sunday night, according to the Houston Chronicle, just before his interview with CBS's "60 Minutes" was about to air.

Clemens claims McNamee was threatened with jail if he didn't connect the pitcher to steroids, according to the suit, the Chronicle reported on its Web site early Monday. The suit was filed in Harris County civil courts, the paper said.

Clemens, who was scheduled to hold a late afternoon news conference Monday in Houston, asked the court to declare that he has not defamed McNamee, the paper said.

The seven-time Cy Young award winner sounded indignant and defiant in his first interview since McNamee accused him of using steroids and human growth hormone, setting up a potential confrontation if the pair testify under oath at a Jan. 16 hearing.
