MLB.com's Brian McTaggart reports that the Rockies have acquired Wilton Lopez from the Astros. No word yet on who the Astros will receive in return, but the Denver Post's Troy Renck reported earlier that it was expected to be two pitching prospects. A potential deal last week sending Lopez to the Phillies was nixed reportedly due to a physical concern with the righty, so don't etch this one down in stone until he passes a physical.
