The Houston Chronicle informs us that Astros GM Tim Purpura has inquired about the availability of pitchers Jake Peavy and Jason Jennings. Peavy has the same agent, Barry Axelrod, as Craig Biggio and Jeff Bagwell. According to Axelrod:
"I know there have been inquiries about Peavy," Axelrod said. "I can’t say for sure, but I think Houston was one of the teams."
Of course, they are still waiting on a decision from Andy Pettitte.
