Roger Clemens says his weekend start for the Sugar Land Skeeters of the Independent League isn't part of a comeback to the Major Leagues.

"I don't know how much clearer I can say it," Clemens said. "I'm nowhere near major league ready, nor have I been training or pitching in that type of mode."

Astros owner Jim Crane has said that the team is open to the idea of adding the seven-time Cy Young Award winner and is sending a scout to the game.

Clemens has a personal services contract with the Astros.
