Clemens attended Wednesday's Astros-Dodgers matchup and sat in the same seats he's had as a season-ticket holder for years -- the first row of the second section behind the plate, just beyond the Diamond Club seats.
"It's not my first time," he said. "We've been here a number of times."
Clemens, whose son, Koby, is a catcher in the Astros' Minor League system, sat with at least one of his younger sons as several people stopped by to say hello, including an Astros clubhouse worker and two batting practice pitchers.
To Clemens, this night was nothing more than a chance to take in a game with his kids.
"I've been seeing [the Astros] and I enjoy it ... we're just running around staying busy. The boys happened to want to come to the ballgame and it worked out perfect, because Roy [Oswalt] was starting tonight. It worked out perfectly."
Asked if he was thinking about making a comeback to the big leagues, Clemens said, "If I did that, I'd get to know [Astros massage therapist] Rohan [Baichu] really well again. I was running sprints yesterday and trying to outrun some 14 year-olds after I caught 20 bullpens. I caught about 12- and 14-year-olds."
Clemens was also interviewed by FS Houston and made a reference to it being obvious he was retired. He then quickly added, "I'm not going to say anything."
