But Clemens' time frame for making a decision on whether he will pitch in 2007 remains the same, according to agent Randy Hendricks.
"I have said we will decide by the end of May, and we will," Hendricks wrote in an e-mail Friday morning.
Last year, Clemens agreed to terms with the Astros at the end of May, and pitched in his first game in the major leagues June 22. He finished the year with 19 starts for Houston, going 7-6 with a 2.30 ERA.
"Roger has been working out and feels good," Hendricks wrote, "but he has yet to ramp up his workouts, the kind where he tortures himself. I have been in communication with all three teams and all three are, of course, interested."
"All of them understand our timetable. If he passes all of his workout tests, mentally and physically, he will more than likely decide to play. But that challenge is very big to him, so don't leap to a premature conclusion."
