A trade of Texas Rangers' right-hander Roy Oswalt is still "possible" before Friday's waiver deadline, reports T.R. Sullivan of MLB.com:

The Rangers are talking to other clubs about pitcher Roy Oswalt and an industry source said a trade is "possible" before Friday’s deadline.

Players must be acquired by Friday to be eligible for post-season.

It is thought that the Los Angeles Dodgers and Washington Nationals could be among the teams interested in Oswalt, who cleared waivers on Tuesday. The Dodgers have been on the lookout for starting pitching help for the last week even though they have already added both Joe Blanton and Josh Beckett to the rotation since the trade deadline, and the Nationals likely need help for when Stephen Strasburg hits his innings limit.

According to Jon Heyman of CBS Sports, however, that the Dodgers have cooled considerably in their interest in Oswalt and may not go after him.

Signed in early summer to add depth to the Rangers' injury-depleted rotation, the 35-year-old Oswalt struggled considerably in eight starts and was demoted to the bullpen. Oswalt has made it well known that he does not want to pitch out of the bullpen, at one point refusing to take the mound in a recent game. In eleven appearances for the Rangers, the veteran right-hander owns a 5.94 ERA and 8.5 K/9 in fifty innings.
