From MLB trade rumors:

Cardinals, White Sox Talking Colby Rasmus
By Luke Adams [July 24 at 10:56am CST]

Despite publicly insisting they don't intend to trade Colby Rasmus, the Cardinals have engaged in discussions with the White Sox about the outfielder, reports Joe Strauss of the St. Louis Post-Dispatch. Strauss says talks between the two teams have "accelerated" within the last few days.

According to Strauss, Edwin Jackson and Matt Thornton are among the players who could interest the Cardinals. The Cards would also be looking for minor league talent from the White Sox, and a third team "may be sought to facilitate a deal."

The Nationals and Rays also remain interested in Rasmus, who has seen a recent decline in his playing time as Jon Jay has taken over as St. Louis's primary center fielder.
