Ken Rosenthal quotes Salty as saying "we are leaning toward nerve inflammation" regarding his shoulder problems and that TX is scouring the trade market for another backup. Add that, to the fact that TX seems to be looking for a bargain bench bat as well per one of his previous posts.
UPDATE(various reports): Salty's symptoms seem similar to TOS but after talking to Harry and Blalock, he doesn't think it is the same thing. More tests to come next week but the Doc says that he doesn't think he can injure his arm if he keeps playing and is taking a "2 weeks of rest" approach to see if he can gain anymore strength in the arm. So he is out until 9/1 at least, and you would expect him to avoid surgery if possible until after the season so that he can be part of the playoff race, given he can't injure his arm any further. But if he can't throw, he can't throw....
Also, Patrick Newman, suggests that a Scheppers to Japan deal is unlikely but his argument seems to be that Scheppers is grandstanding and isn't really serious. However, as I suggested, if he signs a one-yr deal with a Japanese club ("he is auditioning for about 1/2 dozen clubs") he can come back in 2011 and make bank as a FA. In this scenario, his signing bonus is irrelevant.
