The Red Sox have communicated with Roger Clemens's agents, the Hendricks brothers, over the past few days to express their interest in the future Hall of Famer if he elects to play in 2006. Clemens, who was not offered salary arbitration by the Houston Astros, was informed of the contact, and sources close to Clemens said the pitcher reacted positively to the scenario of a return to Boston. ''We had an internal discussion," said Sox CEO and president Larry Lucchino, ''and concluded we should make an initial call to let the Hendricks brothers know we were open to discuss Roger's return if he should have interest in the Red Sox in 2006. ''Nothing further." The theory among those close to Clemens is that if he still wants to pitch, he would return to Houston May 1, the earliest date he can re-sign with the Astros. That way, he can monitor spring training, and the first month of his son Koby's progress; Koby Clemens is a catcher in the Astros organization. But he has surprised people with his decisions before. In an interview with the pitcher during the playoffs, Clemens spoke fondly about Boston and the many friends he still has in the area. ''Here I am, still pitching," Clemens said in October. ''Debbie and I were looking forward to the day where we could just go up to my old neighborhood [Framingham] and just hang out with some of our friends up there. Maybe go to a few games at Fenway. Same in New York. Just grab five or six of your close friends up there and go out to eat and see a ballgame. ''But here I am, still pitching."
