The Astros have had significant discussions with the Orioles about shortstop Miguel Tejada, but the two sides are not close to a deal, according to major-league sources. The Astros apparently believed a trade was possible Wednesday night, telling at least two other clubs that they were on the verge of a major deal. It is not clear whether their focus was Tejada. Astros' officials said Thursday morning that nothing was imminent, suggesting perhaps that the talks had faded. Other sources also indicated that the discussions were not in an advanced phase. A Houston radio station reported Thursday that the Astros were close to acquiring Tejada for shortstop Adam Everett, second baseman Chris Burke and a pitcher.
