Troy E. Renck of the Denver Post says that Berkman is "strongly considering" going to Colorado, with the Rockies hoping that Berkman's desire to stay in the NL will seal the deal.
Berkman and Todd Helton share the same agent, and Helton is reported (by Renck) to be open to the idea of Berkman joining the team.
Renck lists some other teams interested in Berkman:
He also has interest from the Cardinals, Blue Jays and Athletics, among others.
Would Berkman go to St. Louis? I guess Ed Wade may be trying to recount that short conversation he had telling Berkman the Astros weren't interested. Just to remember if he swore at him...
