9:51pm: Manager Tony La Russa told KSDK TV-5 in St. Louis that Rasmus "doesn't listen" to Cardinals coaches, as Austin Laymance and Matthew Leach explain at MLB.com. "That's why he gets in these funks, in my opinion," La Russa said.
1:41pm: Cardinals GM John Mozeliak told Jim Bowden of MLB Network Radio today that nothing has changed since he told Bowden at the All-Star game that he was not shopping Rasmus (Twitter link).
12:04pm: An AL official told Joel Sherman of the New York Post that the Cardinals "are definitely shopping" center fielder Colby Rasmus, despite public denials. The official says the Cards "are asking for a ton." Danny Knobler of CBS Sports agrees, tweeting that the Cards are shopping Rasmus widely. Knobler notes that the Nationals had a scout in St. Louis last night.
The White Sox and Rays have also been linked to Rasmus, but earlier this month GM John Mozeliak said a trade is "highly unlikely." The Mariners have also inquired, tweets Jon Paul Morosi of FOX Sports, and Knobler notes that the Giants have watched Rasmus as a possible Carlos Beltran backup plan.
Even in a down year, the 24-year-old Rasmus is hitting .245/.332/.421 on the season. He's under team control through 2014.
My apologies for an earlier error in which I erroneously attributed the "asking for a ton" quote to the Rays and B.J. Upton.
