PHOENIX — The Diamondbacks traded RHP Edwin Jackson to the White Sox on Friday for rookie RHP Dan Hudson and minor-league LHP David Holmberg.
Jackson, 27, is 6-10 with a 5.16 ERA. That includes a no-hitter against his former team the Rays on June 25. He is owed about $10 million on a contract that runs through 2011.
"I have nothing but good things to say about Edwin," Arizona manager Kirk Gibson said. "We hate to lose him.
Hudson, 23, has been one of Chicago's top prospects, going 30-13 with a 2.90 ERA in 57 minor-league games since being drafted in 2008. In three major-league starts this year, he is 1-1 with a 6.32 ERA.
Holmberg, 19, a 2009 pick, is 3-3 with a 4.02 ERA in 21 games (14 starts) in rookie ball.
Nationals-Rangers: The agent for Washington INF Cristian Guzman said he has approved a trade to Texas. Players with 10 years in the majors, including five with their current club, can't be traded without their consent. Nationals GM Mike Rizzo said he expects the deal to be finalized today, which would be two days after Rangers 2B Ian Kinsler went on the DL with a strained left groin.
Zambrano returns: The Cubs reinstated RHP Carlos Zambrano. He was suspended June 26, a day after his dugout altercation with teammate Derrick Lee. Also, RH reliever Bob Howry was released. He was 0-3 with a 5.66 ERA after signing May 21.
A's: LHP Brett Anderson, out since June 4 with a sore left elbow, was activated. And closer Andrew Bailey went on the DL with a strained right rib cage muscle retroactive to July 20. The team expects him to return when eligible on Aug. 6.
Braves: RHP Kris Medlen left in the sixth after being hit on the right forearm by a pitch. His status has not been determined.
Indians: RHP Mitch Talbot went on the DL with a strained lower back. Talbot was acquired from the Rays for C Kelly Shoppach last offseason. Also, DH Travis Hafner missed his second game because of a sore right shoulder.
Mets: LF Jason Bay went on the DL with a concussion. He was hurt July 23 when he crashed into a bullpen gate while going after a ball.
Phillies: SS Jimmy Rollins returned after missing three games with a bruised left foot.
Tigers: RHP Armando Galarraga, who earlier this year lost a perfect game because of an umpire's blown call, left in the fifth after being hit in the right ankle with a liner. His status hasn't been determined. Also, OF Johnny Damon sat with back spasms and is day to day.
Twins: 1B Justin Morneau, out with a concussion since July 7, played catch and took swings, but there is no timetable for his return. GM Bill Smith said Morneau probably will need a rehab stint before returning.
Rangers sale: A bankruptcy judge rejected a last-minute bid from MLB's preferred buyer, finalizing an auction set for Wednesday and likely to include Mavericks owner Mark Cuban. A group led by Hall of Famer and Texas team president Nolan Ryan offered $520 million and removed side deals that creditors said benefitted owner Tom Hicks. Creditors blocked a previous sale to Ryan's group because of the deals.
Ump out: Plate umpire Wally Bell left the Orioles-Royals game in the sixth with heat exhaustion and dehydration. Bell, 45, who had open heart surgery in 1999, wasn't taken to a hospital, but his status is unknown.
