Astros general manager Tim Purpura spent Wednesday talking to other clubs about trade possibilities. Purpura is hopeful the Astros can make a deal to improve the offense before Monday's deadline, but he said nothing is imminent. "I think deadlines always push people to make decisions," he said. The Astros have shifted their focus more from finding a relief pitcher to adding a bat. Purpura wouldn't divulge any specific trade talks, but a National League official confirmed the Astros still have interest in Baltimore Orioles shortstop Miguel Tejada, though no offer has been made.
