5:14pm: The Orioles are pursuing Koji Uehara of the Rangers as well as McClellan, tweets Ken Rosenthal of FOX Sports. Their pursuit of a reunion with Uehara could complicate the Cards' plan to clear money to sign Oswalt.

3:47pm: The Cards appear to be interested in salary relief more than obtaining a high-end prospect for McClellan, tweets Jon Paul Morosi of FOX Sports. The club could also move Kyle Lohse or Jake Westbrook to the bullpen.

Morosi adds that the club has discussed deals with Oswalt in the range of $7.5MM while the pitcher seeks $10MM. Moving McClellan, who makes $2.5MM, would give the Cards enough room to sign the veteran (Twitter link).

3:16pm: Even though they have interest, the Cardinals' asking price is too high for the Orioles right now, a team source tells Roch Kubatko of MASNsports.com (via Twitter)

2:35pm: The Cardinals are actively shopping versatile righthander Kyle McClellan, writes Joe Strauss of the St. Louis Post-Dispatch. Moving McClellan would allow the club to alleviate a logjam in their bullpen and give them the payroll flexibility to a sign a free agent starting pitcher.

Meanwhile, the Cardinals are looking to clear money in order to sign Roy Oswalt, tweets Jon Paul Morosi of FOX Sports. It was rumored this week that St. Louis was near a deal with the veteran but Morosi stresses that there's no deal in place just yet.

General Manager John Mozeliak recently conceded that the club could possibly deal McClellan but believes it more likely that the he will be with the Cardinals when pitchers and catchers report on February 18th. The Cardinals have attempted to engage a number of clubs in talks for McClellan and the Orioles have emerged as one of the most promising trade partners for him, according to Strauss' industry sources.

The Padres and Diamondbacks are also among the teams that have expressed interest in McClellan.
