KANSAS CITY -- White Sox outfielder Dayan Viciedo has headed out for a rehab assignment with Triple-A Charlotte.
Viciedo, on the disabled list with a left oblique strain, was hitting .229 through 13 games when he was sidelined with the injury.
"He'll have four or five games there to see how he feels and make sure he's all right," White Sox manager Robin Ventura said. "He would have to play in the outfield. There were thoughts of him at DH, but he'll be playing left field."
With the White Sox playing sub-.500 baseball, the temptation could be to get Viciedo back as soon as possible. But the club will guard against bringing back Viciedo back too quickly to protect him from aggravating the oblique.
All systems go for Peavy after bullpen session
KANSAS CITY -- Jake Peavy tested his back by throwing off the mound Monday, after which the right-hander pronounced himself good to go for Wednesday's start against the Mets at Citi Field.
Peavy, who experienced back spasms on Thursday in Texas, worked with a chiropractor and a massage therapist in Kansas City, as well as the regular White Sox training staff. Peavy said he felt good enough that he probably could have pitched in Monday's series finale against the Royals.
"We're all on point to go Wednesday night," Peavy said. "I'm super excited about that, and can't thank our training staff enough. A few days ago, I didn't feel good at all."
Peavy threw for the first time without a grabbing sensation on Sunday. He followed with another positive session Monday and will continue treatment until his Wednesday start.
Peavy will be required to bat in the Interleague road start, but he said that shouldn't pose a problem.
"I'll swing the bat if I need to swing the bat," Peavy said. "If I could pitch in an American League game, I can do the same against a National League team."
• The White Sox will open a two-game series against the Mets on Tuesday night at Citi Field, which will mark a homecoming of sorts for Chicago manager Robin Ventura, who played for the Mets from 1999-2001.
"For me, it was a great time," Ventura said. "My family enjoyed being there. The Mets were very good to me. Going back, you see a lot of people that you are friends with and happy to see."
Ventura made postseason appearances with the Mets in 1999 and 2000.
