Jon Heyman adds to already-established information, that the Astros are interested in finding something called a "Designated Hitter," which sounds like something Bud Selig made up, much like an "All-Time QB," that can't possibly be real.
Nevertheless, that's what the Astros are after. Heyman says Berkman is a possible fit were the money to be right. But he also adds Carlos Pena and Travis Hafner as "in the mix." Whether he's just picking out names based on whose agents he sees in front of him, or if they're actual possibilities, is undetermined.
