The Oakland A's sent All-Star Dan Haren and prospect Connor Robertson to the Arizona Diamondbacks on Friday for pitchers Brett Anderson, Dana Eveland and Greg Smith, infielder Chris Carter and outfielders Aaron Cunningham and Carlos Gonzalez. Haren will join a talented pitching corps that already includes Cy Young Award winner Brandon Webb and starters Doug Davis and Livan Hernandez that helped carry the D-backs to the 2007 National League Championship Series. Arizona also hopes to get Randy Johnson back from injury next year. "We are thrilled to acquire Danny Haren. His addition will bolster an already-strong starting staff and will help stabilize our roster over the next several years," Diamondbacks Senior VP/GM Josh Byrnes said. "Our success in scouting and player development allowed us to make a rare trade like this. We certainly traded many quality players, but we have the youth and depth to justify such a trade."
