Yankees pitcher Andy Pettitte’s meeting with a congressional committee investigating drug use in baseball was postponed until Monday.

He originally was slated to appear for a deposition or transcribed interview tomorrow. But the date was changed today, the latest in a series of switches to the schedule of when witnesses will meet with staff members before testifying Feb. 13 before the House Oversight and Government Reform Committee.

Also asked to appear at that hearing are seven-time Cy Young Award winner Roger Clemens, his former personal trainer Brian McNamee, his former teammate Chuck Knoblauch, and former Mets clubhouse employee Kirk Radomski.

“Mr. Pettitte is cooperating voluntary with the committee, and we look forward to his testimony on Monday,” panel chairman Henry Waxman and ranking Republican Tom Davis said in a joint statement. “We appreciate Mr. Pettitte’s willingness to assist the Committee.”
