I think it's pretty well established that, if free agent starter Roy Oswalt had his druthers, next season he would pitch for either the Texas Rangers or the St. Louis Cardinals. He doesn't seem to have a whole lot of interest in pitching for the Boston Red Sox, despite their interest in him.
Of course, there's that problem that we've referred to a few times - neither the Rangers nor the Cardinals presently have room in their rotations for another starter. The Cardinals might make room. The Rangers don't look like they're going to. Jeff Wilson:
A baseball source said that the Rangers are not likely to sign free-agent right-hander Roy Oswalt, who informed them earlier this week that he doesn't want to pitch in relief.
The source said that the Rangers don't want to remove Matt Harrison from the starting rotation to make room for Oswalt [...]
It might sound crazy, if you just think of Roy Oswalt as being Roy Oswalt. But last season, Matt Harrison started 30 games - for Texas - and posted a 3.39 ERA with 126 strikeouts and 57 walks. Also, Harrison's 26. Harrison's a valuable asset, and at this point in the offseason the Rangers probably couldn't ship him away for a pile of prospects.
So. Oswalt's probably not a fit in Texas. It would appear that this leaves St. Louis and Boston, although you never know if there might be a mystery suitor. What an unusual sweepstakes this has become.
