Astros general manager Jeff Luhnow reportedly spoke with the former Astros first baseman on Thursday and Friday, and while the 36-year-old hasn't commented publicly on whether he plans to play in 2013, the team might be interested in the switch-hitting slugger's services next season.
"Obviously, if he feels he's healthy and ready to play, we'll have a conversation with him. He's still got a lot of value to add to a Major League team."
Berkman's possible role with the Astros is a bit murky, as Houston signed Carlos Pena to be the team's designated hitter last month and currently has a full 40-man roster, but Berkman has been in contact with the organization since November, so an agreement doesn't seem out of the question.
Berkman spent 1999-2010 with the Astros before being traded to the New York Yankees, and posted an impressive .301/31/94 line with the Cardinals in 2011 but played only 32 games in 2012 with a knee injury. He spent last fall as an assistant coach at Rice University, his alma mater.
