Jeff Wilson of the Fort Worth Star-Telegram reports that trading Koji Uehara to the Athletics could free up money for the Rangers to make a run at free agent right-hander Roy Oswalt. Ken Rosenthal of FOXSports.com speculated that the Rangers would go after left-handed reliever Mike Gonzalez with the money saved by dealing Uehara, but Wilson is hearing otherwise. It's well documented Oswalt would prefer to pitch for either the Rangers or the Cardinals in order to be closer to his home in Mississippi, but neither club looks like an easy fit. The Red Sox are also lingering in the background.
