Joe Strauss of the St. Louis Post-Dispatch reports that the Cardinals are "actively shopping" right-hander Kyle McClellan. The Cards want to sign veteran Roy Oswalt and are trying to clear payroll space in order to make it happen. Strauss lists the Orioles, Padres and Diamondbacks as having interest in McClellan, who avoided arbitration with the club by agreeing to a $2.5 million contract earlier this month. He could be used as a starter or a reliever with his new team.
