OAKLAND -- In pursuit of their first victory of a frustrating road trip, the Red Sox went to battle on Sunday afternoon without Jacoby Ellsbury.

The center fielder has had some nagging discomfort in his right wrist of late, and Sunday's day game following a night game seemed like the most logical time to get him a break.

"Yeah. Kind of a scheduled one," said manager Bobby Valentine. "His wrist has been barking at him a little. When we set off on the road trip, the training room was hoping that one of these days would work. See if we can't get it to feel a little better."

Without Ellsbury, Valentine gave Pedro Ciriaco his first career start in the outfield. Ciriaco got the nod in left while Scott Podsednik moved to center.

Making the Red Sox even thinner in the outfield, Ryan Kalish has also been banged up of late with shoulder woes.

"His shoulder has been keeping him from swinging in a game," said Valentine. "It felt a little better yesterday, but he still had treatment after batting practice. He's not really a game-ready guy."

Acquired in blockbuster trade, De Jesus called up

OAKLAND -- The Red Sox will get a look at one of the prospects they acquired in the blockbuster trade with the Dodgers, as they added Ivan De Jesus to the roster for Sunday's game against the Athletics.

De Jesus is a utility infielder who gives the Red Sox depth, not to mention insurance in the event that Dustin Pedroia's wife Kelli goes into labor during this West Coast trip.

The Red Sox are out west until Wednesday, when they complete a three-game series in Seattle.

Last week, the Sox dealt Adrian Gonzalez, Josh Beckett, Carl Crawford and Nick Punto to the Dodgers for four prospects, including De Jesus.

The 25-year-old De Jesus played in 40 games over two seasons with the Dodgers, hitting .231 with no homers and five RBIs.

In seven games for Triple-A Pawtucket, De Jesus hit .385 with a .429 on-base percentage.

Atchison ready for Minors rehab assignment

OAKLAND -- Scott Atchison's season once appeared to be over, but it now appears more likely than not that the righty reliever will return to the Red Sox at some point this month.

Atchison, who injured the ulnar collateral ligament in his right elbow but didn't require Tommy John surgery, threw batting practice on Saturday. He is expected to pitch in a game for Triple-A Pawtucket on Monday.

Before the injury, Atchison was an invaluable piece for the Red Sox this season, posting a 1.76 ERA in 37 games.
