This is a rumor, but it's pretty detailed and comes from someone who at
least claims to be a somewhat-reliable source. I won't vounch for the
credibility of this, but at least it sounds good. Saw this on the
largest Yahoo! Astros Group, Houston's Brand of Baseball, at
http://sports.groups.yahoo.com/group/houstonsbrandofbaseball/.

"Clemens will be an Astro, my aunt works for the team and they will
announce a press conference either 11 AM Friday or Noon Monday
that Clemens will join the club for the remainder of the season. She
begged that I not post this tonight but Oh well, you read it here 1st,
remember that!!!"

She just deleted her post, too (sorry you can't visit the site to see
it for yourself), which suggests it's true, and she went with her
aunts' wishes after all.
