ESPN's Jerry Crasnick hears that Lance Berkman remains at the top of the list in the Astros' search for a designated hitter. Crasnick hears that the Astros aren't interested in other aging DH-types like Hideki Matsui, Johnny Damon, Travis Hafner or Jason Giambi, so they will likely try to add a low-profile name if things with Berkman don't work out. No surprise, money is the biggest hurdle to a potential reunion.
