4:14pm: The Astros are discussing possible trades involving Lance Berkman, according to Ken Rosenthal of FOX Sports (via Twitter). Joel Sherman of the New York Post reported this afternoon (via Twitter) that a high-ranking executive told him the Astros could move Berkman and start rebuilding.
Like former teammate Roy Oswalt, who was traded to Philadelphia earlier today, Berkman has a no-trade clause and can veto any deal. About $5.4MM remains on Berkman's $14.5MM salary this season. The Astros hold a $15MM option for next year, but they can buy it out for $2MM. Berkman is hitting .245/.372/.436 so far in 2010.
