Ken Rosenthal is reporting that the Astros are out of the running for Tejada.  So through the process of elimination, the Rangers are the only team reamining in the sweepstakes, although that doesn't mean the deal is going to happen.

Interesting note:
The asking price was Oswalt, Ensberg and 3rd player.  However the Astros refused to make the deal in fears that the Orioles would flip Oswalt to the Rangers for the Blalock, Arias & Diamond deal.  Which would leave the O's with two third basemen, and prime to make another deal.
