As of Monday afternoon, Astros owner Drayton McLane said general manager Tim Purpura had not asked him to approve a trade for Cincinnati slugger Adam Dunn. According to a report, the Astros have been working on a deal to acquire Dunn for prospects Ezequiel Astacio, Taylor Buchholz and Fernando Nieve. "He hasn't brought anything to me," McLane said of Purpura. "That's why you're catching me totally off guard. I don't know of anything like that, but we would have to look at what we'd have to give up. "You look at each of the last six years, we've given up two to four players every year. So it catches up to you." Purpura later told the Chronicle the rumored trade was a "media fabrication."
