Astros Notes: Rowland-Smith, Hall, Cust, Rodriguez

The Rangers are grabbing all the headlines, but the other Texas team has been busy, too. The latest on the Astros:

• Houston is interested in Ryan Rowland-Smith, according to Brian McTaggart of MLB.com (on Twitter).
• The Astros think they could get more offense from second base and have expressed interest in Bill Hall, according to MLB.com's Brian McTaggart. The Yankees and Dodgers have also shown interest in Hall this offseason. Clint Barmes and Jeff Keppinger figure to play short and second for the Astros unless GM Ed Wade makes an addition.
• The Astros and Mariners are pushing for Jack Cust, according to Joel Sherman of the New York Post (on Twitter). Seattle's interested in a number of free agents, including the former A's slugger.
• Hall and Cust are free agents, but the Astros haven't ruled out making a trade or two. Wade told McTaggart that he exchanged trade proposals with teams today, though Houston's advances weren't embraced by rival clubs (Twitter link).
• Wandy Rodriguez changed agents from Barry Praver to Adam Katz, according to Zachary Levine of the Houston Chronicle (on Twitter). Rodriguez is set to discuss an extension with Houston.
