Eaton starts rehab assignment at Triple-A

NEW YORK -- Adam Eaton will begin a rehab assignment with Triple-A Charlotte on Saturday against Norfolk.

His rehab is not expected to be lengthy and Eaton could join the White Sox as early as the start of their next homestand on Tuesday.

"You're looking at the trainers that are down there, they're going to find out what he's feeling, how he's feeling. You go from there," White Sox manager Robin Ventura said. "We're not going to be able to see him to be able to judge that. By what they say, you have a pretty good idea that when he comes back, he's going to be completely healthy."

Eaton has been on the disabled list with a strained right oblique since Aug. 9. He believes the initial injury happened on a swing on Aug. 8 against the Mariners, but a wall collision a few days prior while tracking down a home run is thought to be a contributing factor.

He bruised his lower back during that collision, adding to the litany of injuries he has experienced during his first season with the White Sox. Eaton has been limited to 94 games this season, missing time for the oblique and lower back, a broken middle finger and a right hamstring strain.

When he has been in the lineup, Eaton has been extremely productive. He ranks among the American League leaders in triples (seven), on-base percentage (.370) and batting average (.304) and is hitting .435 during his last 22 games, while anchoring the team's defense in center.

Guerra returns to White Sox bullpen

NEW YORK -- The White Sox activated reliever Javy Guerra from the bereavement list on Saturday after the right-hander missed six games.

Guerra arrived with the team in New York on Friday, but the White Sox wanted to give him an extra day to do some more throwing on the side.

He will replace left-hander Eric Surkamp, who was optioned to Triple-A Charlotte following Friday night's 4-3 loss to the Yankees. Surkamp allowed one run and struck out two in 1 2/3 innings in the defeat.
